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 con-
taining 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.
