A motorcycle engine oil needs to deliver higher performance than oils used in a car. Automobile engine oil functions mainly as a lubricant for the engine, while the transmission and differential have separate lubrication systems. In a motorcycle, the engine, clutch and transmission all need to be lubricated by just a few litres of engine oil.

Under normal running conditions, the oil contents of a motorcycle engine will make a full circulation of the engine every 10 seconds, performing a multitude of important functions along the way.

Yamaha develops oils specifically for its range of motorcycles, outboard marine engines, WaveRunners and SSVs/ROVs, and supplies them under the Yamalube name.

Whether it's on water, on the road, in dirt or mud, Yamalube oils have been created with a clear understanding of the environments they will be used in.

 

CLEANING
Suppresses the generation of impurities, and prevents them from accumulating on engine parts.

COOLING
Absorbs the heat generated through combustion and friction, then disperses it outside.

WEAR REDUCTION/CORROSION PREVENTION
Reduces friction and wear on sliding and rotating parts. While preventing rust and corrosion of metal surfaces.

SEALING
Prevents leakage of compressed and explosive gasses, and increases the level if airtightness in the combustion chamber.

An engine is often referred to as the heart of a machine, but with so many parts and components rotating and revolving at high speeds, it is a harsh environment. So if the engine is the heart, the oil is the blood. And just like blood, oil has many roles to play in keeping the engine healthy and long-lasting.
