Your Yamaha engine has been designed to use
regular unleaded gasoline with a pump octane
number [(R+M)/2] of 86 or higher, or a research oc-
tane number of 91 or higher. If knocking (or ping-
ing) occurs, use a gasoline of a different brand.
Use of unleaded fuel will extend spark plug life and
reduce maintenance costs.
Gasohol
There are two types of gasohol: gasohol contain-
ing ethanol and that containing methanol. Gasohol
containing ethanol can be used if the ethanol con-
tent does not exceed 10% (E10). Gasohol contain-
ing methanol is not recommended by Yamaha
because it can cause damage to the fuel system or
vehicle performance problems.
