Different structure The engine of the car is separately lubricated from the transmission and the clutch. The temperature of the oil in the crankcase is between 75 and 90 °C. The four-stroke motorcycle engine includes a wet multi-plate clutch, a high-speed and transmission gear, a shifting mechanism, and moving parts such as a piston, a cylinder, an intake and exhaust valve, etc., all in the same structure, sharing the oil in the same volume, and the friction of the clutch. The rotation of the plate and the shifting gear generates a lot of heat, and the temperature of the oil in the crankcase can be up to 80-120 °C. Different cooling effect The engine oil capacity of a car engine is about 5-7L, while the engine oil of a four-stroke motorcycle engine is only about 1L. Only when the engine oil is fully flowing can the heat dissipation performance be exerted. The amount of oil has a great influence on the heat dissipation performance. In addition, most motorcycles are generally air-cooled. Only a few are water-cooled. The cooling effect is much worse than that of the car's water tank. Even the water cooler is because of its water. The capacity is less than that of the car and the heat dissipation is poor, which inevitably causes the engine oil temperature of the motorcycle engine to be much higher than the temperature of the automobile oil. Different oil filters The car's oil filter is quite complete, with a strainer and fine filter, the filter effect is very good, and the four-stroke motorcycle is very different. In order to reduce the weight and volume of the motorcycle, the oil filter is relatively simple in design, and it is not surprising that the filtration effect is poor. Fourth, the power is different The displacement power of a car is generally 60-80Kw/L, while that of a four-stroke motorcycle is 100-120Kw/L, which is about 1.5 times that of a car, and the volume power is twice that of a car. Different calibration speed The calibration speed of an automobile engine is usually 3000-5000r/min, while the calibration speed of a motorcycle engine is about 8000-11000r/min, which is 50% to 120% higher than that of a car. At maximum power output, the speed of the motorcycle engine is between 10,000 and 15,000 r/min, while that of the car is between 4000 and 5000 r/min and the maximum is no more than 6000 r/min. Different strength Due to differences in driving conditions and various technical requirements, the strength of the motorcycle engine is usually 3-4 times higher than that of the car. The body of the motorcycle is light and often travels at the maximum power or maximum torque output. The engine temperature is not only high but also wears out. It can be seen that the working environment of motorcycles is much more demanding than cars. Summary: Therefore, due to the structural difference between the motorcycle engine and the automobile engine, the oil specially formulated for the motorcycle is different in composition from the automobile. Motorcycle oil pays special attention to the high temperature resistance of oil and excellent thermal oxidation stability. It can effectively remove deposits on engine parts, prevent sludge generation, protect the engine from damage under harsh conditions, and provide better engine. Protection to extend the life of the engine. In addition, the "integrated" design of the motorcycle engine, that is, the clutch, the starting mechanism, the shifting gear and the transmission gear are integrated with the engine crankcase, and the lubricating system and the same lubricating oil are shared with the engine to ensure the lubrication of the engine. At the same time, it is necessary to maintain proper friction characteristics to ensure smooth starting, smooth operation and no slipping of the clutch.

Have you ever seen someone using car lubricants to add to the motorcycle , I believe there is, and there may be no problem in the short term, so I mistakenly believe that car lubricants are completely no problem for motorcycles. It was not until I saw these data that the motorcycle should use motorcycle-specific lubricants. Why?
