Why does car oil last 10 times longer than motorcycle oil?

Experts explain that motorcycle oil is usually mineral-based while car oil is synthetic-based, which is why car oil lasts 10 times longer than motorcycle oil.

More importantly, motorcycle engines work harder than car engines with higher rpm, the cooling system is not as good as car engines because it is too small so the oil has to work at very high temperatures, the quality is therefore quickly reduced and needs to be replaced soon.

Experts also say that the difference between changing oil for cars and motorcycles is related to many factors, including engine size, how it operates, and the level of lubrication of friction parts.

Specifically, with engine size, cars usually have larger engines than motorcycles. Larger engines also mean that there are more frictional parts that need to be lubricated. This requires a larger amount of oil than motorcycles to protect the parts and reduce friction.

High heat resistance because car engines usually generate more heat than motorcycle engines. Therefore, in terms of quality, car oil is designed to withstand higher temperatures and maintain good viscosity in high temperature environments and run more durably than motorcycle oil.

Depending on the oil change cycle: Motorcycles usually require shorter oil change cycles than cars, possibly because motorcycles are usually required to operate at higher power levels than cars.

Regarding the type of oil used: There are many different types of engine oil and car oil often has different additives and chemical complexes, better than motorcycle oil to meet the specific requirements of the engine.

Regarding operating conditions: Motorcycles often operate under higher energy conditions and at higher rotational speeds than cars. This creates more heat and pressure, placing strict requirements on lubricating oil and requiring early replacement.
