Why Yamalube

YAMALUBE oil is a Genuine YAMAHA Part
born of the engineers' passion and belief that
engine oil is an important liquid engine com-
ponent. We form teams of specialists in the
fields of mechanical engineering, chemistry,
electronics 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 bal-
ance of additives to make sure the final oil
clears our performance standards. Thus, Ya-
malube 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 Yama-
lube the best choice for your Yamaha en-
gine.

Gasoline

Use a good quality gasoline that meets the
minimum octane rating. If knocking or ping-
ing occurs, use a different brand of gasoline
or premium unleaded fuel. Yamaha recom-
mends that you use alcohol-free (see Gaso-
hol) gasoline whenever possible.

Gasohol
There are two types of gasohol: gasohol con-
taining ethanol (E10) and that containing
methanol. Ethanol can be used if the ethanol
content does not exceed 10% and the fuel
meets the minimum octane ratings. All etha-
nol blends containing more than 10% etha-
nol can cause fuel system damage or cause
engine starting and running problems.
Yamaha does not recommend gasohol con-
taining methanol because it can cause fuel
system damage or engine performance
problems.

Fuel requirements

Recommended fuel:
Regular unleaded gasoline
Min. research octane number (RON):
90
Do not use leaded gasoline. Leaded
gasoline can seriously damage the en-
gine.
Avoid getting water and contaminants
in the fuel tank. Contaminated fuel can
cause poor performance or engine
damage. Use only fresh gasoline that
has been stored in clean containers.
