Yamalube is Yamaha’s proprietary brand of lubricants, formulated specifically for their engines. This ensures compatibility and optimized performance, taking into account the unique design and operational characteristics of Yamaha motorcycles. The “4” indicates it’s a 4-stroke engine oil, while “20W-40” refers to its viscosity rating.

Decoding 20W-40 Viscosity

The “20W-40” designation is a crucial aspect of yamalube 4 20w40 motorcycle oil. It’s a multi-grade oil, meaning its viscosity changes with temperature.

  • 20W: The “W” stands for “winter,” and the number preceding it indicates the oil’s viscosity at cold temperatures. A lower number means the oil is thinner when cold, allowing for easier starting and quicker lubrication of engine components during cold starts.
  • 40: The second number indicates the oil’s viscosity at normal operating temperatures. A higher number means the oil maintains a thicker film at hot temperatures, providing better protection against wear under extreme conditions and high engine loads.

This specific viscosity blend ensures that the oil flows freely to protect components during cold starts, yet remains robust enough to provide excellent lubrication and reduce friction when the engine is hot and working hard. This balance is vital for both engine longevity and consistent performance.

The Role of Additives in Yamalube 4

Beyond its base oil, yamalube 4 20w40 motorcycle oil contains a carefully selected blend of additives. These additives perform various critical functions:
