Use gasoline with a pump octane rating of 86 or higher.
We recommend unleaded gasoline because it produces fewer engine and spark plug
deposits and extends exhaust system life.
Never use stale or contaminated gasoline or oil/gasoline mixture. Avoid getting dirt or water in the
fuel tank.
Occasionally you may hear light 'spark knock" or "pinging" (metallic rapping noise)
while operating under heavy loads. This is no cause for concern
if spark knock or pinging occurs at a steady engine speed. under normal load, change brands of
gasoline. If spark knock or pinging persists, see an authorized generator dealer.
Running the engine with persistent spark knock or pinging car cause engine

Oxygenated Fuels
Some gasoline are blended with alcohol or an ether compound to increase the octane These gasoli-
ne are collectively referred to as oxygenated fuels. some areas of the United States use oxygenated
fuels to help meet clean air standards.
If you use an oxygenated fuel, be sure its pump octane rating is 86 or higher.
Ethanol (ethyl or grain alcohol)
Gasoline containing more than 10% ethanol by volume may cause starting or
performance problems. Gasoline containing ethanol may be marketed under: the name "Gasohol".
Methanol (methyl or wood alcohol)
Gasoline containing methanol must contain cosolvents and corrosion inhibitors to protect the fuel
system. Gasoline containing more than 5¾ methanol by volume may cause starting and/or perfor-
mance problems and may damage metal. rubber and plastic parts of your fuel system.
