EAU86110
Your Yamaha engine was designed to
use premium unleaded gasoline. Con-
firm the pump octane number [(R+M)/2
method] is 91 or higher, or the research
octane number (RON) is 95 or higher. If
engine knocking or pinging occurs, use
a gasoline of a different brand or higher
octane rating.
Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that contain-
ing methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10% (E10). Gas-
ohol containing methanol is not
recommended by Yamaha because it
can cause damage to the fuel system
or vehicle performance problems.
NOTICE
ECA11401
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,
as well as to the exhaust system.
