FUEL
TYPE OF FUEL TO USE
•
Use clean, fresh, regular unleaded gasoline with a
minimum of 85 octane. Fresh fuel prevents gum from
forming in the fuel system or on essential carburetor parts.
Purchase fuel in quantity that can be used within 30 days.
•
Do not use gasoline which contains Methanol.
•
Do not mix oil with gasoline.
•
For engine protection use Briggs & Stratton Gasoline
Additive available from your Authorized Briggs &
Stratton Dealer (P/N 5041 or single use pouch).
•
This engine is certified to operate on gasoline. Exhaust
Emission Control System: EM (Engine Modifications).
CAUTION: Some fuels, called oxygenated or reformu-
lated gasoline, are gasoline blended with alcohols or
ethers. Excessive amounts of these blends can damage
the fuel system or cause performance problems. If any
undesirable operating symptoms occur, use gasoline
with a lower percentage of alcohol or ether.
ADDING FUEL
WARNING
[1] Fill fuel tank outdoors or in well-ventilated area,
away from sparks, open flames, pilot lights, heat,
and other ignition sources.
[2] If fuel spills, wait until it evaporates before starting

[3] Turn engine OFF and let engine cool at least 2
minutes before removing gas cap.
[4] Remove cap. Fill tank to approximately 1-1/2 inches

OIL PRESSURE SWITCH
If engine is equipped with an oil pressure switch, the switch
will either activate a warning light or stop the engine when
the engine runs low on oil. (Read the operating instructions
supplied by the equipment manufacturer to determine
which way your engine is equipped because the equipment
manufacturer supplies the oil pressure gauge.)
See OIL PRESSURE on page 12 for oil filling instructions.
