Fuel Recommendations
Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane / 87 AKI (91 RON). For high
altitude use, see below.
• Gasoline with up to 10% ethanol (gasohol) is acceptable.
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. Use of unapproved fuels will cause
damage to engine components,
which will not be covered
under warranty
.
To protect the fuel system from gum formation, mix a fuel
stabilizer into the fuel. See the appropriate
Operator's
Manual
for recommendations. All fuel is not the same.
If starting or performance problems occur, change fuel
providers or change brands. This engine is certified to
operate 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.
For carbureted engines, high altitude adjustment is
required to maintain performance. Operation without this
adjustment will cause decreased performance, increased
fuel consumption, and increased emissions. Contact
a Briggs & Stratton Authorized Service 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 recommended.
For Electronic Fuel Injection (EFI) engines, no high altitude
adjustment is necessary.
Adding 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 3 minutes
before removing the fuel cap.
• Extinguish all cigarettes, cigars, pipes, and other
sources of ignition.
• Fill fuel tank outdoors or in a 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.
1. Clean the fuel cap area of dirt and debris. Remove the
fuel cap (A, Figure 5).
2. Fill the fuel tank with fuel. To allow for expansion of the
fuel, do not fill above the bottom of the fuel tank neck (B).
3. Reinstall the fuel cap.

transmission oil tank only supplies oil to one transmission.
The level of oil in both transmission tanks must be checked,
and if necessary, filled.
Oil Type:
20W-50 conventional detergent motor oil.
