Why Yamalube
YAMALUBE oil is a Genuine YAMAHA Part born of
the engineers’ passion and belief that engine oil is
an important liquid engine component. We form
teams of specialists in the fields of mechanical en-
gineering, chemistry, electronics and track test-
ing, and have them develop the engine together
with the oil it will use. Yamalube oils take full ad-
vantage of the base oil’s qualities and blend in the
ideal balance of additives to make sure the final oil
clears our performance standards. Thus,
Yamalube mineral, semisynthetic and synthetic
oils have their own distinct characters and value.
Yamaha’s experience gained over many years of
research and development into oil since the
1960’s helps make Yamalube the best choice for
your Yamaha engine.
