2-Stroke Engine Oil - Yamaha VINO YJ50RR Owner's Manual

INSTRUMENT AND CONTROL FUNCTIONS
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 octane number of 91 or
higher. If knocking
occurs, use a gasoline of a different
3
brand or premium unleaded fuel. Use
of unleaded fuel will extend spark
plug life and reduce maintenance
costs.
Gasohol
There are two types of gasohol:
gasohol containing ethanol and that
containing methanol. Gasohol con-
taining ethanol can be used if the
ethanol content does not exceed
10%. Gasohol containing methanol is
not recommended
because it can cause damage to the
fuel system or vehicle performance
problems.
