Fuel Recommendations
Fuel must meet these requirements:
• Clean, unleaded gasoline.
• A minimum of 87 octane / 87 AKI (91 RON). SeeHigh
Altitude Requirements.
• Gasoline with up to 10% ethanol (gasohol).
NOTICE Do not use unapproved gasoline, such as E15
and E85. Do not mix oil in gasoline or change the engine
to operate on alternative fuels. Use of unapproved fuels
will cause damage to engine components, which will not be
covered under the warranty.
To protect the fuel system from gum formation, mix a fuel
stabilizer into the fuel. SeeStorage.All fuel is not the same.
If start 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 Requirements
• At altitudes over 5,000 feet (1,524 meters), a minimum 85
octane / 85 AKI (89 RON) gasoline is acceptable.
• For carbureted engines, high altitude adjustment is
required to remain emissions compliant. 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.
