Yamalube is designed for the most grueling conditions your outboard faces. Whether it's extended full-throttle operation, or engine pushing "out of the hole" acceleration, or even hour after hour of trolling, this yamalube oil stands up to the test. 

Each Yamalube oil is made from base oils, additives, and solvents in combinations specific for the application. For example, the additive package for Yamalube 2-M is outboard oil is very different from our Yamalube 2-R for motocross motorcycles, even though both are liquid-cooled 2-stroke engines. These two engine types have different stress loads, with the outboard often operating for extended periods under heavy load while the motocross engine is subjected to frequent bursts of throttle under extreme conditions. Consequently, the oils developed for these engines have different lubrication formulas.
