_SPECIFICATIONS
FUEL REQUIREMENTS ENGINE SPECIFICATIONS
The "Q" series generator is equipped with a gasoline
fuel system as standard equipment. Specific installa¬
tions may provide either a separate fuel tank for the
generator, of the generator may "share" the vehicle
engine's fuel tank.
NOTE: Some installations using a "shared" fuel tank
may have a generator fuel pickup tube that is shorter
than the vehicle engine's pickup tube. Such an arrange¬
ment causes the generator engine to "run out of gas"
while adequate fuel in the vehicle remains in the tank.
To reduce lead and carbon deposits use high quality
UNLEADED gasoline with the generator. Leaded REG¬
ULAR grade gasoline is an acceptable substitute.
NOTE: Using "Unleaded'1 gasoline contributes to
longer engine valve life by reducing lead and carbon
deposits.
CAUTION: Generac does not recommend usina any
gasoline containing alcohol (such as ugasohor"). If
you use any gasoline containing alcohol, It must not
contain more than 10 percent ethanol and it must be
removed from the tank during storage. Do NOT use
any gasoline containing methanol. If you use gas¬
oline with alcohol. Inspect more frequently for fuel
leaks and other abnormalities.
ENGINE OIL REQUIREMENTS
Use a high quality detergent oil classified "For Service
SF" and with an oil viscosity rating of SAE 10W-30 oil.
Do not pour in any additives to the recommended oil.
Engine crankcase capacity is 1.5 U.S. quarts. See
MAINTENANCE section for oil level check and filling
procedures.
