Can a 125cc Motorcycle Use Car Engine Oil?
1 Answers
125cc motorcycles should not use car engine oil because the performance requirements for oil in motorcycle engines differ from those in cars. Long-term use of car engine oil may lead to poor lubrication and increased wear. The reasons why 125cc motorcycles cannot use car engine oil are as follows: Structural Differences: Car engines have separate lubrication systems for different components, while motorcycle engines share lubrication with other parts. Therefore, car engine oil and motorcycle engine oil differ in their working principles. Cooling Effects Differ: Car engines use radiators for cooling, whereas motorcycles rely on air cooling, which is significantly less effective. Additionally, motorcycle oil capacities are smaller than those in cars, which further limits the cooling efficiency of motorcycles. As a result, the cooling requirements for motorcycle engine oil differ from those for car engine oil.
