Fuel
Use unleaded gasoline ONLY. DO NOT use any
gasoline additives. We recommend the use of clean,
fresh, unleaded gasoline intended for automotive use.
High octane gasoline should NOT be used with the
engine on this unit.
Engine Oil
Use high quality detergent oil of at least API (American
Petroleum Institute) service class SF or SG. Select the
viscosity based on the air temperature at the time of
operation as shown in the following table. NOTE:
Using less than service class SF or SG oil or extending
oil change intervals longer than recommended can
cause engine damage. The recommended SAE
viscosity grade is 10W-30.
