Fuel Recommendations
Fuel must meet these requirements:
Clean, fresh, unleaded gasoline.
A minimum of 87 octane/87 AKI (91 RON). High altitude
use, see below.
Gasoline with up to 10% ethanol (gasohol) is accept-
able.
NOTICE: Do not use unapproved gasolines, such as E15
and E85. Do not mix oil in gasoline or modify the engine to
run on alternate fuels. This will damage the engine compo-
nents and void the engine warranty.
To protect the fuel system from gum formation, mix a fuel
stabilizer into the fuel. Refer to “Storage”. All fuel is not the
same. If starting or performance problems occur, change fuel
providers or change brands. This engine is certified to oper-
ate on gasoline. The emissions control system for this engine
is EM (Engine Modifications)
High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum 85
octane/85 AKI (89 RON) gasoline is acceptable. To remain
emissions compliant, high altitude adjustment is required.
Operation without this adjustment will cause decreased per-
formance, increased fuel consumption, and increased emis-
sions. See a Briggs & Stratton Authorized Dealer for high
altitude adjustment information.
Operation of the engine at altitudes below 2,500 feet (762
meters) with the high altitude adjustment is not recommend-
ed.
How To Add Fuel
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When Adding Fuel
Turn engine off and let engine cool at least 5 minutes
before removing the fuel cap.
Fill fuel tank outdoors or in well-ventilated area.
Do not overfill fuel tank. To allow for expansion of the
fuel, do not fill above the bottom of the fuel tank neck.
Keep fuel away from sparks, open flames, pilot lights,
heat, and other ignition sources.
Check fuel lines, tank, cap, and fittings frequently for
cracks or leaks. Replace if necessary
If fuel spills, wait until it evaporates before starting
engine.
