Generac Power Systems NP-50G Series

Generac NP-50G Recreational Vehicle Generator
FUEL REQUIREMENTS
The “NP” series generator is equipped with a gasoline fuel
system. Specific installations may provide either a separate
fuel tank for the generator, or 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 arrangement causes the gen¬
erator engine to “run out of gas” while adequate fuel for the
vehicle remains in the tank.
To reduce lead and carbon deposits use high quality
UNLEADED gasoline with the generator. Leaded REGULAR
grade gasoline is an acceptable substitute.
NOTE: Using “Unleaded" gasoline contributes to longer
engine valve life by reducing lead and carbon deposits.
CAUTION: Generac does not recommend using
any gasoline containing alcohol (such as “gaso-
hoi”). If you use any gasoline containing alcohol,
It must not contain more than 10 percent ethanol
and it must be removed from the generator during
storage. Do NOT use any gasoline containing
methanol. If you use gasoline with alcohol,
inspect more frequently for fuel leaks and other
abnormalities.
ENGINE OIL REQUIREMENTS
Use only high quality detergent oil rated with API service clas¬
sification SF, SG, or SH. The recommended oil weights include
the following:
• During summer months: SAE 30. An acceptable substitute
isSAE 10W-30.
• During winter months: SAE5W30. DO NOT USE SAE 10*
W40.
Crankcase and oil filter capacity is about 1400ml or about 1.5
U.S. quarts. Use no special additives. See “Maintenance" sec¬
tion for oil level check and fill procedures.
