Why Yamalube; Coolant - Yamaha T155 2021 Owner's Manual

Periodic maintenance and adjustment

Why Yamalube

YAMALUBE oil is a Genuine YAMAHA
Part born of the engineers' passion
and belief that engine oil is an impor-
tant liquid engine component. We form
teams of specialists in the fields of me-
chanical engineering, chemistry, elec-
tronics and track testing, and have
them develop the engine together with
the oil it will use. Yamalube oils take full
advantage of the base oil's qualities
and blend in the ideal balance of addi-
tives to make sure the final oil clears
7
our performance standards. Thus,
Yamalube mineral, semisynthetic and
synthetic oils have their own distinct
characters and value. Yamaha's expe-
rience gained over many years of re-
search and development into oil since
the 1960's helps make Yamalube the
best choice for your Yamaha engine.

the coolant level. A slight tilt to the
side can result in an incorrect
