Which Motorcycle Oil Viscosity Should I Use?

31 août 2026

Choosing the right motorcycle engine oil is important for smooth performance, proper engine protection and long engine life. In Mauritius, where motorcycles and scooters are regularly exposed to warm temperatures, traffic and frequent stop-and-go riding, choosing the correct viscosity matters.

What does 10W-40 mean?

10W-40 describes how the oil flows at different temperatures.

10W = how the oil behaves when the engine is cold.

40 = how the oil protects the engine when it is hot.

For many modern motorcycles and scooters, 10W-40 is a popular choice when it matches the manufacturer's recommendation.

Is 10W-40 good for motorcycles in Mauritius?

Yes, when recommended by the motorcycle manufacturer. Motul offers high-quality 10W-40 motorcycle oils designed to provide reliable engine protection, smooth operation and excellent performance under demanding riding conditions.

Motul's 10W-40 range includes options such as Motul 5000, Motul 5100 and Motul 7100, depending on your motorcycle and required specification.

What about 20W-50?

20W-50 is a thicker oil at operating temperature than 10W-40. It can be suitable for certain motorcycles, especially when the manufacturer recommends it.

Always check your motorcycle owner's manual before choosing between 10W-40 and 20W-50.

Is thicker oil always better?

No. Thicker does not automatically mean better protection.

The best viscosity is the one specified for your motorcycle. Using the wrong viscosity can affect lubrication, engine performance and fuel economy.

Motul 5000, 5100 or 7100 — which should I choose?

It depends on your motorcycle and how you ride.

Motul 5000 is a quality semi-synthetic option for everyday riding.

Motul 5100 provides enhanced protection and performance for riders looking for a higher-performance semi-synthetic oil.
