Does Using Car Engine Oil Affect Motorcycles?
1 Answers
Motorcycles should not use car engine oil. Engine oil is the lifeblood of an engine, and its quality and performance directly affect the vehicle's lifespan. The following are the working conditions of motorcycle engine oil: 1. High temperature and large temperature differences: When the engine is running, the temperature of the piston top and combustion chamber walls ranges between 250-500°C; the piston skirt ranges from 260-175°C from top to bottom; the main bearings and crankcase oil temperature are between 85-95°C, while at startup, the temperature of engine components is close to the ambient temperature. 2. Heavy load: Modern engines have high power, large horsepower, and are lightweight, resulting in significant friction load per unit area on moving parts. 3. Fast movement speed: The engine crankshaft typically operates between 1,500-4,800 RPM; the piston speed can reach 8-14 meters per second. Forming a lubrication film on friction surfaces is very difficult, and the piston and cylinder walls often operate under boundary lubrication conditions.
