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.
Your Yamaha engine has been designed
to use regular unleaded gasoline with a
research octane number of 91 or higher.
If knocking (or pinging) occurs, use a
ECA10070
gasoline of a different brand. Use of
unleaded fuel will extend spark plug life
and reduce maintenance costs.
