In the daily maintenance of cars and motorcycles, the selection of oil is a very important link. Although both are internal combustion engines, due to their different structure, use environment and working conditions, there are great differences in the performance and use of automobile oil and motorcycle oil. This article will introduce the difference between automobile oil and motorcycle oil in detail to help owners better understand and choose the right oil.

1. Different structures

The structural design of cars and motorcycles is very different, which also leads to the difference in the lubrication system between the two. The engine, transmission and clutch are lubricated separately and each has its own lubrication system. This design ensures that the individual components are sufficiently lubricated to extend their service life.

The structure of the motorcycle is relatively simple, the engine, transmission, clutch and other high-speed moving parts are in the same structure, sharing the same volume of oil. Although this design can reduce the weight and volume of the whole machine, it also brings some problems. Since each component shares the same volume of oil, once the oil problems, it will directly affect the operation of the entire system.

2. Different capacity

The oil capacity of a car engine is usually about 5 to 7 liters, while the oil volume of a motorcycle engine is only about 1 liter. This is mainly due to the difference in engine displacement and working conditions between the two. Car engines usually have larger displacement and require more oil to ensure lubrication and cooling. While the motorcycle engine displacement is small, the amount of oil required is relatively small.

In addition, there is a difference in oil change cycles between cars and motorcycles. The oil change cycle of a car is usually 5,000 to 10,000 kilometers, while the oil change cycle of a motorcycle is shorter, usually 2,000 to 3,000 kilometers. This is mainly because the working conditions of the motorcycle engine are more severe, wear is greater, and the oil needs to be changed more frequently.

3. Oil filtration is different

The oil filter of the automobile is relatively complete, with a coarse filter and a fine filter, and its filtration effect is excellent. The coarse filter can filter out larger impurities, while the fine filter can filter out smaller impurities to ensure the cleanliness of the oil. This design can extend the service life of the oil and reduce engine wear.

In order to reduce the weight and volume of the motorcycle, the oil filter is relatively simple in design, and the filtration effect is not good. Some motorcycles do not even have a special oil filter, but filter through the oil pump and the oil pan. Although this design can reduce costs, it is also easy to cause impurities in the oil to enter the engine and accelerate the wear of the engine.

4. Different performance requirements

Due to the different working conditions and use environments of cars and motorcycles, there are also great differences in the performance requirements of oil. Automotive oil is usually required to have high oxidation resistance, wear resistance and cleanliness to adapt to the work of automotive engines at high speed, high temperature and high load conditions.

The motorcycle oil requires a high viscosity index, shear resistance and foam resistance, in order to adapt to the motorcycle engine at low speed, high torque, high vibration conditions. In addition, motorcycle oil is also required to have good lubricity and tightness to ensure the normal operation of the clutch.

5. Brand and price differences

There are also some differences in the brands and prices of motor oil and motorcycle oil. The automotive oil market is highly competitive, with many brands and large price differences. The motorcycle oil market is relatively small, there are fewer brands, and the price is relatively high. This is mainly due to the high production cost of motorcycle oil, high technical requirements, and small market demand.

In short, there are great differences between automobile oil and motorcycle oil in terms of structure, capacity, filtration, performance and brand. When the owner chooses the oil, he should choose the right oil according to his own model, the use of the environment and working conditions to ensure the normal operation of the engine and extend the service life. At the same time, it is also very important to change the oil regularly and do a good job of engine maintenance.
