Frequently Asked Questions (FAQs)

1. Is motorcycle oil different than car oil?

They are not interchangeable at all. A motorcycle oil will lubricate both the engine and the gear box and also acts a coolant. The motorcycle oil will have higher viscosity, slightly higher frictional characteristics and low ash content. The car oil, on the other hand, is only used to lubricate the engine.

2. Can you use car oil in a motorbike?

Can I use car oil in a motorcycle? Car oil is designed to work in the engine, with a different oil in the gearbox. And the clutch is usually dry. Besides the fact that bike engines usually rev a lot higher, the oil in the engine also has to have additives that help it work with the much higher loads of a gearbox.
