FUEL RECOMMENDATIONS
Use clean, fresh, leadĆfree, regular gasoline with a minimum of
85 octane. Leaded gasoline may be used if it is commercially
available and if unleaded is unavailable. Purchase fuel in
quantity that can be used within 30 days. See storage
instructions.
In U.S.A. leaded gasoline may not be used. Some fuels, called
oxygenated or reformulated gasolines, are gasolines 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.
This engine is certified to operate on gasoline. Exhaust
Emission Control System: EM (Engine Modifications).
Do not use gasoline which contains Methanol. Do not mix oil
with gasoline.
For engine protection, we recommend using Briggs & Stratton
Fuel Stabilizer available from an Authorized Briggs & Stratton
Service Dealer.
ADDING FUEL
WARNING
Before refueling, allow
engine to cool 2 minutes.
Clean around fuel fill before removing cap to refuel. Remove
