How to change the oil in a 4T scooter engine with your own hands?

Everyone who takes the path of a motorbike enthusiast is faced with the problem of choosing and changing oil for a scooter or motorcycle. While some people change it immediately after purchase, others travel several thousand kilometers and only then change the oil. But there are also those who do not change it at all; this, of course, does not last long. To choose which oil is suitable for your scooter, you need to know the type of engine of your scooter. There are two-stroke (2t) and four-stroke (4t) scooters. Accordingly, there is oil for 2t and 4t scooters. For each of them there are three types of oil: mineral, synthetic and semi-synthetic.

Let's decide on the type of oil that suits your scooter. To do this, determine the type of engine: two-stroke or four-stroke. After this, you can start making your selection.

How to change the oil in a scooter gearbox yourself?

The first step is to select transmission oil for the scooter. In general, this is quite easy to do, you just need to follow the manufacturer's recommendations. You can also use motor oil with a viscosity of 10W-30
, especially if your scooter does not sit idle during the cold season, this composition will be more liquid, which means you have a reserve of viscosity for cold weather.
In addition, ATF
, characterized by excellent fluidity and excellent protective properties.

Having selected the desired fluid, you can proceed directly to replacing it. This can only be done on well-warmed-up equipment, so you can ride it first or simply warm up the gearbox for twenty minutes. This way, the old oil will become thinner and easier to drain, and all the dirt and debris that has settled at the bottom will rise and come out along with the liquid.

Next, having previously wiped the drain and filler holes, unscrew the nuts from them (first from the filler hole, then from the drain hole). Then, replacing the container, remove the old oil. At this time, you can wash all the removed bolts and nuts in gasoline. When there is no drain bolt, the oil is changed using only one bolt; in this case, the scooter should be tilted on its side. It is better to fill in new liquid using a medical syringe, drawing the required amount into it. Most often, the required volume is stamped on the gearbox housing, but if there are no such instructions, then you can fill it to the bottom of the bolt thread.

The first time you should change the oil after 500 km, then every 1000. It is also recommended to change the oil after carrying out work on the cylinder: replacing the cylinder, removing the cylinder head, etc., since during these works, even if everything was done carefully, there is a possibility dirt and metal particles getting into the engine. You will need a wrench with a head (most likely 19).

The oil change must be carried out when the engine is warm - this way the oil becomes more fluid, and dirt, if any, rises from the bottom of the crankcase, mixing with the oil. The scooter must be placed on the center stand.

Work order:

  • Unscrew the filler cap (dipstick), located on the right side of the engine, next to the generator
  • Place a container (about 1 liter) under the drain hole to drain the used oil and unscrew the drain plug counterclockwise. To unscrew, use only the head - an open-end wrench can damage the drain plug, which is made of aluminum. Under the plug there is a spring and an oil filter - mesh
  • Drain the oil
  • Wash the drain plug and filter in gasoline
  • Screw in and tighten the drain plug. Don't overdo it - remember that the plug and crankcase are made of aluminum. Excessive force may damage the threads.
  • Pour 800 ml of engine oil into the engine through the filler neck using a suitable funnel.
  • Tighten the filler cap

Oils for winter and summer

To accurately change the oil, you need to use a watering can.
Automotive oils are divided into all-season, summer and winter. They differ in composition. For understanding and the opportunity to purchase exactly what you need, it is marked with Latin letters and numbers. The marking of winter automobile oils must contain the letter “W” (in English, winter). The numbers in the abbreviation indicate viscosity. The higher the indicator, the greater the consistency (viscosity) and, accordingly, vice versa.

Maximum viscousness suitable for use in hot summer periods. You should not pay attention to the letters SAE in the abbreviation. These letters indicate the classification of motor oils, which for scooter owners means nothing other than the viscosity indicator. You need to know that if the oil is marked with SAE letters and numbers, you can safely buy it for pouring into a scooter gearbox in hot weather. If the letter W is present, the oil is suitable for winter.

Preparation

To ensure that all the used oil leaves the engine without any residue, the engine should be thoroughly warmed up before changing the oil. Or, what would be best, start changing the oil immediately after a 5-10 km trip.

The second preparatory stage is that we need to prepare in advance a flat area on which to install the scooter in the most level position possible and prepare a suitable container for used oil.

The tools you use also play an important role. Don't skimp - buy a new head with a knob. You will only need two of them: for 17 and 10. Those who neglect this point pay dearly later, and out of their own pocket.

Scooter with four stroke engine

For scooters with a regular gearbox, 4t oil is suitable, but if your scooter has a CVT gearbox, then you need gear oil. In the case of a 4t scooter, the choice of oil comes down to the same principle as for a 2t. That is, it all depends on the riding style, the technical condition of the moped and also its age. If we talk about four-stroke mopeds, then it is recommended to fill them with 10w-40 oil. In principle, a moped can run on regular car oil, but use such oil at your own peril and risk. The oil must protect all rubbing parts well, and there are a large number of them in the engine. And the scooter clutch especially needs high-quality oil, since it literally floats in oil.

If we are talking about what kind of oil to pour into cubic capacity motorcycles, then two-stroke synthetic is better. This way the cylinder-piston group will remain clean and well preserved. This oil is the most resistant to various temperatures. Also, synthetic scooter oil produces less soot, which settles in the muffler and clogs it.

Why change the oil

I met a person who did not change the oil for 3 seasons. His ATV was being repaired and there was little left of the oil, everything was covered in soot. And the engine was working in this one, it’s good that it was still working at all. But it significantly reduced its service life, and the repairs cost a pretty penny.

As mentioned, a good synthetic oil prevents the formation of carbon deposits and is resistant to temperatures. Carbon deposits interfere with engine operation and reduce its service life, complicate the life of compression rings and cause overheating. And given that the amount of carbon deposits is constantly increasing, plus constant overheating, repairs will not take long. And expensive motorcycles require expensive repairs. Therefore, it is not recommended to skimp on oil.

The first time you should change the oil after 500 km, then every 1000. It is also recommended to change the oil after carrying out work on the cylinder: replacing the cylinder, removing the cylinder head, etc., since during these works, even if everything was done carefully, there is a possibility dirt and metal particles getting into the engine. You will need a wrench with a head (most likely 19).

The oil change must be carried out when the engine is warm - this way the oil becomes more fluid, and dirt, if any, rises from the bottom of the crankcase, mixing with the oil. The scooter must be placed on the center stand.

Work order:

  • Unscrew the filler cap (dipstick), located on the right side of the engine, next to the generator
  • Place a container (about 1 liter) under the drain hole to drain the used oil and unscrew the drain plug counterclockwise. To unscrew, use only the head - an open-end wrench can damage the drain plug, which is made of aluminum. Under the plug there is a spring and an oil filter - mesh
  • Drain the oil
  • Wash the drain plug and filter in gasoline
  • Screw in and tighten the drain plug. Don't overdo it - remember that the plug and crankcase are made of aluminum. Excessive force may damage the threads.
  • Pour 800 ml of engine oil into the engine through the filler neck using a suitable funnel.
  • Tighten the filler cap

Top 5. ELF Scooter 4 City

Rating (2021): 4.69

13 reviews from resources were taken into account: Yandex.Market, Otzovik

Pure synthetics The oil is completely synthetic, which puts it above its closest competitors that use semi-synthetic production technology. High quality product especially for scooters.

  • Characteristics

    Price per liter: 550 rub.

  • Country: France
  • Type: synthetic
  • Viscosity: 10W-40

Among oils for scooters with 4-stroke engines, synthetic products are quite rare. They are expensive to produce, and since the scooter itself is an unpretentious piece of equipment, semi-synthetics are quite suitable for it. But the French brand ELF doesn't think so. This is a synthetic lubricant of the highest quality. It is suitable for all types of scooters. Recommended by manufacturers such as Honda, Kawasaki and Suzuki, even though they have their own motor oils. At the same time, the price tag does not deter. 550 rubles per liter is, of course, not little, but not much either. Note that some top manufacturers charge much more, even for mineral water.

Advantages and disadvantages

  • Maximum quality
  • Affordable price for synthetics
  • Recommended by top scooter manufacturers
  • Cannot be mixed with other lubricants
  • The choice of viscosity is very poor

Gearbox design in the T4 scooter

The gearbox consists of a set of gears, which are located in a common housing - in the crankcase. Thanks to the presence of the crankcase, all parts are located compactly. The crankcase protects all elements from mechanical damage and contamination, providing good lubrication of gearbox parts.

A gearbox is necessary to adjust the speed of rotation of the shafts down or up. On a scooter, this element is located between the secondary clutch shaft and the wheel.

The gearbox is divided into primary and secondary gears:

  • The primary gear is the first and second gears.
  • The secondary gear includes the third and fourth gears.

Both gears always consist of two gears - one large and the other small.

There is a hole in the gearbox housing for draining and filling fluid. The filler plug is just a regular bolt and washer. Transmission oil is poured into the scooter. It is advisable to check the fluid level in the crankcase once a month.

If the oil level has dropped or is completely absent, the gearbox begins to make an extraneous noise. Extraneous noise is produced by worn gears with a small amount of lubricant. And this will lead to wear of gears, bearings and bushings.

Draining the oil and flushing the gearbox

So, having selected the right lubricant for the regulator, you can begin to drain the old oil. Changing the scooter oil in the gearbox is carried out when the scooter is warmed up. To do this, it is enough to ride a scooter for 20 minutes before the change process. The heated liquid becomes more liquid, and this will help quickly drain the waste along with dirt or metal debris.

Draining the oil and flushing the gearbox:

  • Wipe the drain and filler (bolt) holes with a clean rag.
  • The filler hole is located at the rear of the power unit.
  • Unscrew the nuts from the filler bolt, and then from the drain hole.
  • Substituting an empty container, drain the old liquid.
  • While the old oil is draining, wash the removed nuts and bolts in gasoline.

If metal particles are found when draining the old oil, the regulator housing should be flushed. To do this, remove any remaining lubricant from the crankcase and fill in transmission oil to flush it. The viscosity of the flushing fluid should be higher.

To flush the gearbox housing, you must:

  • Tighten the drain bolt and then the filler hole.
  • Start the power unit and rev it up a little.
  • Drain the washing mixture.
  • Tighten the drain hole.

This completes the process of draining the old fluid from the scooter gearbox. Changing the oil in the gearbox of a 4t 50q scooter is completed by filling in new fluid.

Filling with new oil

After draining the old lubricant and flushing the gearbox system, all that remains is to fill the transmission oil. Moped manufacturers recommend using the following modifications 75W90, SAE 80W90, 85W90 with API quality class: GL-4; GL-5.

The required volume of lubricant is always indicated on the gearbox. Use a large syringe to take the required amount of oil and pour it into the filler hole.

If you don’t have a syringe, you can simply fill the liquid to the lower level of the filler hole. The vehicle must be in an upright position when filling the oil. After pouring oil into the T4 scooter gearbox, wipe the filler bolt and plug dry. Carefully tighten the filler bolt and check the tightness of the connections.

In conclusion, I would like to note that the long-term performance of the scooter gearbox depends on regular maintenance such as timely replacement of transmission fluid.

How to make a replacement?

It is better to change this component immediately after the trip. In this state, it is warmed up and will flow out perfectly, which will ensure a minimum residue of old fluid in the gearbox. You should take the brand recommended by the scooter manufacturer. You also need to strictly adhere to the recommended volume.

The required oil volume can be seen on the gearbox.

To replace, place the vehicle level on the main stand. Next, you need to unscrew the drain bolt (if there is one) and wait until all the liquid is drained into a specially prepared container. If there is no such bolt, drainage is carried out through a single bolt. To do this, you need to tilt the scooter on its side. It is worth noting that the oil, which has not been changed for a very long time, has a dark blue color, close to black. But if you notice that the liquid has a metallic color, this means that abrasion has occurred on the working surfaces of the gears. But it’s not so scary, there’s no need to worry. This will not affect the operation of the vehicle in any way. After this, you need to tighten the drain bolt and unscrew the filling hole.

The required volume is most often indicated on the element of the rear gearbox (numbers are stamped). If nothing is specified, carefully read the description of the scooter. Typically, the amount of oil for a scooter whose engine volume does not exceed 50 cm³ is 100 g. You need to take the liquid into a syringe, preferably one with a 20 ml capacity, and pour it into the gearbox. If there is no syringe, oil must be filled to the lower level of the thread of the filler bolt. This is exactly the mark (maximum correct volume). Replacement should only be done with the scooter in an upright position. After the component is poured, the working surface must be wiped with a dry, not dirty cloth and the screw must be tightened.

Gearbox oil change timing

That is why, for reliable operation of the scooter as a whole, it is necessary to observe the timing of fluid replacement. In most cases, the frequency of oil changes and the recommended lubricant class are indicated in the manufacturer's instructions. If there is no information about the timing of the change, the oil in the scooter gearbox is changed every three to five thousand kilometers or once a year.

A sufficient oil level in the gearbox reduces shock loads, vibrations and extraneous noise. Due to the enormous loads on a Chinese scooter, constant care of the vehicle is required. After a certain time or mileage, the oil loses its quality, becoming saturated with metal elements and forming sediment. And this will lead to a deterioration in the lubricating properties of the fluid, without providing reliable protection. Without sufficient fluid in the gearbox, this part may quickly break down.

When purchasing a new vehicle, changing the oil in the gearbox on a scooter is done more often. The first fluid change on a new scooter is carried out after 300 km, and the second time after 1000 km. But the quality and reliability of driving a moped also depends on the required oil level in the gearbox. In order for the level to comply with the standards, it is necessary to check it every 2.5 thousand kilometers and, if necessary, top up the fluid.

Considering the timing of fluid changes, we must not forget about the correct choice of oil. When purchasing lubricant, you should always take into account the recommendations of the scooter manufacturer. The gearbox can be filled with Motul Scooter Gear transmission oil, although its volume is only 150 ml; liquid with viscosity 80W-90 or 75W-90. It is allowed to fill the gearbox with motor oil with a viscosity of 10W-30. The most acceptable fluid option for a scooter is ATF gear oil, which has good fluidity and excellent protection properties.

SAE classification

The latest edition of the classification divides motor oils into 11 classes: 6 winter (0W, 5W, 10W, 15W, 20W, 25W) and 5 summer (20, 30, 40, 50, 60) viscosity classes. The letter W (Winter) before the number means that the oil is adapted to work at low temperatures.

Most motor oils on the market today are all-season, that is, they meet viscosity requirements at both low and high temperatures and have a double designation, for example in our case: SAE 15W-40 . The first number characterizes the pumpability of the oil at low temperatures. If you subtract 35 from the first digit, you get the minimum temperature at which a safe cold start of the engine is possible. The second number is an indicator of oil viscosity at 100 degrees Celsius. If you add 5 to the second digit, you get the maximum permissible air temperature at which the oil can be used.

Scooter oil - 2t, 4t, types of oils

One of the essential attributes of any vehicle is oil, because it allows your engine to operate properly and smoothly. A scooter also needs quality oil and so we will look at the process of choosing this product.

As you probably already know, according to the type of engine, a scooter is divided into 2-stroke and 4-stroke, so for this purpose different types of oil have been created that meet the requirements of the engine. You can buy scooter oil for your engine in any store; the choice of oils is so wide that you will only have to decide on the price. But it is also worth knowing that there are also two types of oils - synthetic and mineral. But we will start with choosing oil according to engine type.

Oil for 4t engine

When choosing oil, first of all pay attention to the price. If you want your scooter to work smoothly and the engine not to overheat, buy expensive oil from a branded manufacturer

Expensive oil has already proven itself in the market, and therefore most scooter riders use it. To select the right oil, read the owner's manual for your scooter model, which will indicate the scooter's viscosity rating. But if you do not have such a manual, we will recommend standard indicators for 4t scooters.

As a standard, such scooters should be equipped with motor oil with a viscosity of 15W40 and 10W40. For them, there is a separate temperature regime and level of wear of your engine. In case of significant wear on your engine, use oil with a viscosity of SAE 20W-50.

Oil for 2t engine

Engines with two-stroke systems have a slightly different approach to choosing oil, and here the quality of the product plays an important role rather than viscosity. As you should know, all Japanese small-capacity scooters with a 2T engine have a separate oil tank, from which the oil goes to the oil pump, and then to the fuel mixture. That is why such motors require a special lubrication system. Since such a motor goes through a full circle in 2 strokes, at this time the resulting oil should not only burn together with the fuel, but also create a small but high-quality film. High-quality oil should not leave residue, mixing and dissolving in full.

Types of motor oil

Also, motor oil for scooters is made into three types - synthetic, semi-synthetic and mineral. Let us immediately note that synthetic oil is the highest quality and most productive; it burns faster without leaving a negative residue. This type will always be a leader, because the manufacturer tries to follow innovations and modernize the composition of the oil. Mineral motor oils are considered the cheapest and lowest quality, so we strongly do not recommend using them. The use of a mineral product has a negative effect on the engine - it causes a lot of carbon deposits, the scooter loses power or has trouble starting. The worst result is a breakdown of the piston group, which overheats and jams due to lack of oil.

In conclusion, here are some of the highest quality and most popular types of motor oil for scooters (2t and 4t)

Manufacturers of motor oils:

  • Motul
  • Castrol
  • IPone
  • Liquid moly
  • Mannol
  • ZIC
  • Lukoil

Features and principle of operation of the 2t engine

Any owner of a motorcycle should have an understanding of the design of the engine and the principle of its operation. The two-stroke power unit is used not only in motorcycles, but also in other technical devices - gas mowers, trimmers and others. Despite the fact that many models of modern equipment are equipped with four-stroke engines, the two-stroke engine is still widely used. It is easy to operate, convenient to maintain and repair, and is also quite reliable.

The operating cycle of such an engine is carried out in a couple of compression and power strokes as a result of the energy from the ignition of the fuel. Both cycles are carried out during one revolution of the crankshaft. A two-stroke engine does not have the fuel mixture intake phase and the exhaust cycle, characteristic of four-stroke engines. The process of fuel intake and exhaust gas exhaust occurs during the compression and expansion phases.

Thanks to this design feature, the torque and power developed by the engine are increased at the same cubic capacity as a 4-stroke engine. And although the efficiency of a two-stroke power plant is lower compared to a four-stroke one, due to the two-stroke operation of the piston, the engine elements perform fewer movements. Provided that the mating parts of the motor are properly lubricated, it has a fairly long service life and is less susceptible to internal wear.

For a two-stroke to function, it is necessary to turn on the ignition, ensure the fuel supply and crank the engine crankshaft with a starter or kickstarter.


The two-stroke power unit is used not only in motor vehicles.

Further operation of the two-stroke engine is carried out according to the following algorithm:

  • The piston begins to move towards the spark plug from bottom dead center. At this time, the fuel mixture enters the working chamber of the cylinder. The exhaust window, designed to allow exhaust gases to escape, opens and the working mixture is compressed;
  • in the initial phase of the compression cycle, a pressure difference occurs in the chamber of the crank mechanism, facilitating the entry of a new portion of gasoline. In the upper phase of the piston movement, the working mixture is ignited by a spark from a spark plug;
  • The energy resulting from the combustion of gasoline forces the piston to move to the lowest point. Thanks to the open channel of the exhaust window, exhaust gases exit through the elbow connected to the muffler;
  • subsequent movement of the piston causes the purge channel to open and gasoline to flow into the working area of ​​the cylinder. The phase of displacement of the piston to the lowest point completes the working cycle of the motor and the cycle repeats.

In the process of supplying gasoline mixed with oil, the components of the power unit are lubricated. This distinguishes the lubrication system of a two-stroke engine from the lubrication system of a four-stroke engine, which has a gear pump to supply oil to the area of ​​the mating parts of the engine.


Oil mixed with gasoline provides lubrication in the crank mechanism

Changing engine oil

Draining used oil

We place the scooter on the center stand; if it is crooked, we straighten it. On the left side in the direction of travel of the scooter, at the very bottom of the engine, look for the drain plug, place a previously prepared container under the plug and unscrew the drain plug with a 17mm head.

While the oil is draining, go to the right side of the scooter and unscrew the dipstick and the oil filter plug, which is located at the very bottom of the engine.

We put a good 17 socket on the plug, unscrew it and remove it with all its contents from the engine.

This is the oil filter. Immediately after unscrewing it, while the point is still important - throw all this junk into clean gasoline, give it a good shake, and then blow it out and dry it.

After the oil filter plug is removed from the engine. In order to remove any remaining oil from the engine, pump the engine several times using the kickstarter.

Then we wait about five minutes - wipe the drain holes dry, for greater reliability, apply sealant to the plugs and screw them into place.

Filling the engine with new oil and checking its level

Depending on the design of the canister, pour oil into the neck either directly from the canister itself or through a funnel. The funnel must be clean!

Oil level control

The oil level is checked as follows: pour the first portion of oil into the engine, approximately 600-700 ml, wait a couple of minutes until the oil spreads evenly over the crankcase without twisting, insert the dipstick all the way into the filler neck, remove it and check the level.

The oil level must be within the control area.

  • If the level is lower, add a little oil, wait a couple of minutes and take a measurement.
  • If the oil level is higher than normal, drain it or, better yet, pump it out using a syringe with a tube from the neck.

The control area is indicated by red arrows. In my case, the oil level is exactly in the middle of the control section and is indicated by a blue arrow. Ideally, the oil level should be near the upper boundary of the control section. But this is ideal, but in practice, the average level is quite acceptable and does not in any way affect the reliability and durability of the engine.

What to fill the gearbox with?

When you choose oil for a scooter gearbox, the question often arises, which is better in terms of base quality, composition and price.

All oils are divided into three types based on their base:

The choice of oil depends on the season.

The synthetic type includes those whose packaging bears the designation Fully Synthetic. Such components retain their original properties more than others and are resistant to overheating and low temperatures.

Semi-synthetic is most suitable for engines with considerable mileage. Semi-Synthetic - this is how semi-synthetic fluid is usually designated. There are impurities, which makes the cost of products lower and the quality worse (when compared with synthetic ones).

Mineral is designated Mineral. The cheapest, as it is a product of oil waste. These components tend to thicken quickly and, when boiling, leave deposits on the engine.

Mixing different based components is not allowed.

Scooter with four stroke engine

For scooters with a regular gearbox, 4t oil is suitable, but if your scooter has a CVT gearbox, then you need gear oil. In the case of a 4t scooter, the choice of oil comes down to the same principle as for a 2t. That is, it all depends on the riding style, the technical condition of the moped and also its age. If we talk about four-stroke mopeds, then it is recommended to fill them with 10w-40 oil. In principle, a moped can run on regular car oil, but use such oil at your own peril and risk. The oil must protect all rubbing parts well, and there are a large number of them in the engine. And the scooter clutch especially needs high-quality oil, since it literally floats in oil.

If we are talking about what kind of oil to pour into cubic capacity motorcycles, then two-stroke synthetic is better. This way the cylinder-piston group will remain clean and well preserved. This oil is the most resistant to various temperatures. Also, synthetic scooter oil produces less soot, which settles in the muffler and clogs it.

Why change the oil

I met a person who did not change the oil for 3 seasons. His ATV was being repaired and there was little left of the oil, everything was covered in soot. And the engine was working in this one, it’s good that it was still working at all. But it significantly reduced its service life, and the repairs cost a pretty penny.

As mentioned, a good synthetic oil prevents the formation of carbon deposits and is resistant to temperatures. Carbon deposits interfere with engine operation and reduce its service life, complicate the life of compression rings and cause overheating. And given that the amount of carbon deposits is constantly increasing, plus constant overheating, repairs will not take long. And expensive motorcycles require expensive repairs. Therefore, it is not recommended to skimp on oil.

And what will happen if you don’t change the oil, you will find out from the video:

How much oil to put in a scooter

Each scooter needs a different amount of oil. But using the golden rule this can be easily understood. After all the oil has been drained from the crankcase, you need to measure how much of it came out and then fill in the same amount plus 3-5 percent. If the scooter is new, then you don’t have to add 3-5%, and fill in as much as you drain.

Top 7. Motul Scooter Expert

Rating (2021): 4.36

23 reviews taken into account from resources: Yandex.Market, Ozone, Otzovik

The best oil for displacement engines It is recommended to fill the lubricant into four-stroke engines with a displacement of 150 cubic meters and above. Provides maximum protection of parts under high loads.

  • Characteristics

    Price per liter: 700 rub.

  • Country: France
  • Type: semi-synthetic
  • Viscosity: 10W-40

If your scooter's engine has a displacement of more than 150 cc, then it requires special oil. Many people try to simply fill in motorcycle lubricants, but, as experts say, this is not the best way out. One solution to the problem is Motul Scooter Expert, an oil designed specifically for large scooters. It makes no sense to pour it into 50 cc engines, although it will not harm them. The product is specially designed for high loads, which is important for large engines. It can also be used in cases of high wear of parts, when it is necessary to compensate for gaps formed over time. Add here an expanded classification, including Japanese types, and we get an excellent product, although quite expensive.

Advantages and disadvantages

  • Recommended for engines from 150 cc
  • Suitable for all four-stroke engines
  • Increased consumption noted
  • Not the most attractive price

How much lubrication is required

  • Any scooter owner needs to understand what kind of oil is recommended to use in their small-displacement engine and exactly how much oil should be filled in for the engine to operate efficiently in any weather. The average is 1-2 liters, but a lot depends on the specific type of scooter and its brand. For a more accurate understanding, the owner should read a book on servicing his scooter or select a model on the website and read the instructions.
  • In a situation where the document cannot be found, it is better to take the advice of repairmen.
  • The amount of liquid itself that you fill during replacement is on average about 1-2 liters. Experienced specialists or owners of small motorcycles will tell you a more accurate parameter. But at the beginning of use it is recommended to fill in about 1.5 liters.

Why is fresh scooter gear oil necessary?

One of the most important components of a scooter can rightly be called the gearbox. It is responsible for timely reducing the speed of the driven shaft, thereby increasing torque. That is, it converts high shaft and clutch speeds into fairly powerful, but low wheel speeds. This part consists of a number of rubbing elements (gears and bearings) that undergo enormous loads, and, as expected, they need good care. It is the transmission oil that provides such care.

It is an oil doped with various functional additives. The main function of transmission fluids can be called protective, as they protect the surface from wear, corrosion, seizing, etc. In addition, thanks to them, energy losses are reduced and heat removal from friction surfaces is ensured. Shock loads, vibrations and noise in gear drives are also significantly reduced.

Changing the engine oil

In 2-stroke technology, the oil does not change, but is regularly poured into a separate tank and supplied by an oil pump to the carburetor, where it is mixed with the air-gasoline mixture and supplied to the engine.

The mixture lubricates the rotating and rubbing parts of the engine, burns and exits with exhaust gases into the exhaust pipe.

Oil tanks on scooters have different volumes - from 0.6 l to 1.3 l.

If you ride a motorcycle every day, then five liters of oil will be enough for a 2-stroke engine for the summer season.

The Oil lamp on the instrument panel indicates that the oil has dropped to the reserve level.

If the lamp lights up, it means that there is little oil left in the tank.

We'll have to capitalize on it. And this, you understand, is time-consuming and expensive repairs.

On 4-stroke 50 cc motorcycles, the oil is changed every 2 - 3 thousand km. During this mileage, fuel combustion substances accumulate in the oil and, as a result, it becomes dirty and thick, which changes its structure and properties.

If you drive together, transport cargo, that is, when the engine often works under heavy loads, then change the oil more often, after 1 - 1.5 thousand km.

Let's get down to business.

Start the scooter for 5 - 10 minutes. until the increased speed drops.

Place the motorcycle on the stand and turn off the engine.

Loosen the drain bolt.

Place a liter jar to drain the waste and unscrew the bolt completely.

Then unscrew the oil dipstick.

In 5 minutes, all the oil will flow out of the engine.

On a Honda Dio 56, there is a filter mesh under the oil drain cover. Wipe it well with a dry cloth and blow it or rinse it in gasoline.

On a Honda Dio 68, the oil filter mesh is located near the variator. The mesh also needs to be removed and washed.

Then reassemble everything in reverse order.

Fill the engine with oil through the dipstick. Its quantity depends on the motorcycle model and is indicated on the oil dipstick.

The level should be up to the top mark of the dipstick.

Screw in the dipstick.

As you can see, the procedure is not complicated, but it requires care and will take 20–30 minutes. It's always difficult to start the first time, but then it will be business as usual for you.

Choosing scooter oil

When purchasing an oil fluid, you need to focus on the viscosity recommended by the manufacturer, taking into account the temperature indicators of the region of use (seasonality). Lubricant mixtures for scooters are usually systematized according to the type of engine for which they are intended to operate.

The limitations are caused by the fundamental difference in the lubrication systems of two- and four-stroke engines. Therefore, when choosing oil for a moped, you must strictly follow the operating instructions and focus on the individual characteristics of the existing model.

Two stroke engine

Two-stroke engines installed on scooters are lubricated with oil fluids, which are first mixed with fuel and then burned in the cylinders along with it. Hence the specific requirements for this group of oils:

  • good solubility in gasoline;
  • low ability to form carbon deposits on the rings and internal surfaces of the muffler;
  • protection of engine parts from wear and corrosion;
  • low ash content;
  • low smokiness of exhaust gases.

Special brands of oils for two-stroke engines:

  1. Eni i-Ride Scooter 2T is a semi-synthetic lubricant that guarantees high-quality engine operation even at high ambient temperatures. The oil has good cleaning properties, anti-wear characteristics, low ash content and low CO content in exhaust gases.
  2. Racing Scooter Synth 2T is a synthetic oil fluid with low smoke, good wear resistance and high lubricity. Prevents the appearance of alkaline and acid deposits on the internal surfaces of the cylinder block. Used for separate and mixed lubrication of two-stroke motorcycle engines.

  3. Racing Scooter 2T Basic is a mineral oil for low-power engines. It cleanses the system well of combustion and wear products. Has optimal lubricity. Can be used for both air- and water-cooled motors.

Scooter with four-stroke engine

Oil for scooters with a four-stroke engine is designed to work in difficult operating conditions. This is due to complex city traffic, where there are frequent stops, alternating driving modes, sudden acceleration, etc.

The specificity of engine lubrication is that some parts are lubricated under pressure using an oil pump - these are the main bearings, the crankshaft and the cylinder head. The remaining rubbing surfaces are washed by spraying or oil mist.

Operational requirements:

  • high thermal properties;
  • low viscosity at low temperatures;
  • low ability to form varnish deposits and soot;
  • antioxidant qualities;
  • protection of parts from corrosion;
  • stable cleaning properties.

Recommendations:

  1. MOTUL Scooter Power 4T is a synthetic oil for powerful scooters with four-stroke engines. The lubricating fluid works well in urban conditions, reduces the friction force in the contact areas of the parts, and ensures stable operation of the clutch mechanism immersed in the engine crankcase. It has good antioxidant, anti-corrosion and dispersing characteristics.
  2. LIQUI MOLY Racing Scooter 4T is a mineral oil fluid for four-stroke engines. Provides high-quality lubrication of engine rubbing surfaces. It has high anti-corrosion, thermal and anti-wear properties.
  3. ENI I-RIDE SCOOTER 4T is a semi-synthetic oil with high performance characteristics. The technical fluid has no temperature restrictions and guarantees reliable wear protection even in the most extreme conditions. Synthetic additives present in the mixture provide good non-stick and washing properties.

Benefits of this oil

Keep in mind that in comparison with most synthetic products from other brands and manufacturers that are made on a hydrocracking basis, this product has an excellent ester base, which ensures operational stability. Also, SCOOTER oil is based on the maximum list of calcium and boron additives: including product analyzes do not show an increase in the amount of aluminum in the lubricant, which is why the wear rate of the pistons will be at the lowest level.

It would also be worth noting that modern SCOOTER lubricants already have a reputation as the most reliable among all - still, the oil was created specifically for scooters with four-stroke engines.

Among the advantages of the lubricant: it is able to maintain the viscosity indicator over time throughout the entire operation of the engine, without going beyond the established norm; the oil also demonstrates better ash content and an almost complete absence of deposits when used.

The viscosity indicator of the composition makes it possible not to worry about the level of performance of the scooter even at normal replacement intervals.

Changing the oil in a scooter transmission

The gearbox is one of the most significant mechanisms in a scooter. It is necessary to ensure that the speed of the driven shaft is reduced in time, due to which an increase in torque will be achieved. In the design of this part, several elements can be distinguished that are constantly subject to friction - gears and bearings. Therefore, these components require timely and proper care. And a long service life of the unit can be achieved by changing the transmission oil on the scooter.

Watch a video on how to change the oil on a scooter.

Considering the high level of loads on the transport gearbox, we can conclude that it needs to be maintained regularly. After the scooter makes a certain mileage, metal dust mixes with the oil and creates a sediment. This results in physical qualities and properties becoming lower.

Changing the oil in the scooter transmission must be carried out in accordance with the manufacturer's requirements. On average, new fluid should be added to replace the old one approximately every 3 thousand km.

Do-it-yourself oil change in the gearbox

Initially, you will need to select the correct oil for the transmission. Usually, there are no difficulties with this

The only thing you have to pay attention to is the manufacturer's recommendations. In addition, you can use oil with a viscosity of 10W-30

This is especially true when the scooter is used during the cold season. Also, ATF transmission fluid performs well, having an increased fluidity value and excellent protective qualities.

When the fluid is selected, you can begin to change the oil in the scooter gearbox. You will first need to warm up the vehicle well by driving it for twenty minutes or simply leaving it running. This will ensure that the old oil becomes more liquid, and dirt particles float to the top and “go away” along with the technical fluid. Otherwise, the process is identical to that described above.

How to change the oil in a scooter fork

You always need to remember the golden and immutable rule: “As much as is drained, so much is poured in.” The only exception to this recommendation is the case when the oil gradually loses volume during vehicle use. In this situation, the amount of fluid required will be dictated by the design of the plug itself and the year it was manufactured.

On average, you need to drain and fill approximately 120-125 ml of oil. After a new volume of liquid enters the unit, it will need to be “pumped” by making a trip. This is necessary to ensure that all the lubricating fluid goes through the cycle completely.

Here another question arises: is it possible to change the oil in a scooter fork by eye? You have to be careful here, as too much lubricant will likely result in the need to buy new seals. And a lack of fluid will result in the piston starting to run dry. Thus, it is necessary to rely entirely on the requirements presented in the operating instructions.

Watch the video about what kind of oil to pour into a scooter gearbox. Tell us about the difficulties you encountered when changing the oil.

Working principle of automatic centrifugal clutch

As you know, the clutch is designed to connect and disconnect the engine and the drive wheels. When the clutch is engaged, the engine and wheels are connected, and the engine transmits torque through the transmission to the wheels. When the clutch is disengaged, the engine and wheels are disconnected, the engine continues to operate, but no torque is transmitted to the wheels. To connect the engine and wheels (via a gearbox), the clutch uses friction. Clutch discs or pads, rigidly attached to the engine shaft, are pressed against the gear disc and begin to rotate it using friction. In a mechanical (manual) clutch, powerful springs are used to press and create friction force.

This clutch is normally always engaged. To release the springs and disengage the clutch, you need to press the hand lever.

An automatic transmission uses centrifugal forces to press the pads down and create friction. When the engine is idling, the automatic clutch is always disengaged. The pads, rigidly mounted on the engine shaft, simply slide along the transmission disk, because the friction force is too small. Moreover, they are kept from contact with the disk and springs. As the engine speed increases, the centrifugal force increases, the pads begin to press harder against the transmission disc, the friction force increases, and torque begins to be transmitted from the engine to the transmission and further to the wheels. At the same time, the friction force increases smoothly, therefore the torque also increases smoothly. This explains the soft operation of the automatic clutch, because it is a kind of shock absorber for transmitting torque.

Most scooters have a chain drive from the gearbox to the drive wheel

This is how the clutch on a scooter works. But the transmission consists of more than just the clutch. Not a single engine in the world is capable of turning the drive wheel in one rotation of the crankshaft. In order for the wheel to make one revolution, the engine rotates the crankshaft several times. To ensure this, a gearbox is used in the scooter's transmission. Usually this is a pair of gears. The small one is rotated by the engine and turns the large gear, which transmits torque to the wheel. That is, for the large gear to turn once, the small one will turn along it several times. The ratio of the diameters of these gears is called the gear ratio of the scooter.

Most scooters have a chain drive from the gearbox to the drive wheel. The chain fits on two sprockets. The drive sprocket is located in the engine. The driven sprocket is located on the wheel. In this case, the gear ratio is the ratio of the diameter of these sprockets.

However, some manufacturers or tuning enthusiasts install a rear axle on a scooter. In this case, the gearbox is not located in the engine, but in the rear axle.

The gear ratio is changed not only by gearboxes, but also by the gearbox. In modern engines, a variator is used for this. It allows you to smoothly change the gear ratio smoothly and without jerking. It is this part of the transmission (variator) that the electric starter rotates when starting. However, electrics may not always work. The wiring or generator may fail, and the electric start will be unavailable. Then Kickstarter will help. The kickstarter device on a scooter is based on the use of muscle force. The kickstarter lever is connected to a gear sector, which, when you sharply press the lever with your foot, rotates the variator, and through it the engine.
