Because motorcycles operate at higher RPMs and closer tolerances than automobiles, the oil is subjected to significantly more stress and thermal degradation. Changing Practices and Best Maintenance.
Understanding Viscosity Numbers: 10W-40 and 15W-50 Explained
Decoding Viscosity and Base Stocks Viscosity, denoted by numbers such as 10W-40 or 15W-50, refers to the oil's resistance to flow. Anti-wear additives protect the gears and bearings, while detergents keep the engine clean by preventing sludge buildup.
The "W" stands for winter, indicating the oil's cold-flow properties, while the second number represents its viscosity at operating temperature. Mineral oils are refined from crude oil and are often the most budget-friendly choice, but they break down faster under high stress and require more frequent changes.
Understanding Viscosity Numbers Like 10W-40 and 15W-50
Using an oil that is not JASO MA or MA2 certified, such as an automotive API SL or SM oil, is strongly discouraged as it can cause the clutch to overheat and fail. Unlike standard car oil, motorcycle lubricants must perform under extreme pressure conditions, particularly within wet clutches where the same oil lubricates the gearbox, clutch, and engine.
