Adding Fuel
Fuel must have these requirements:
• Clean unleaded gasoline
• A minimum of 87 octane / 87 AKI (90 RON)
• Up to 10% ethanol 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 engine
damage that will not be covered under warranty.
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
performance, increased fuel consumption, and increased
emissions. See an authorized service dealer for high altitude
adjustment information. Operation at altitudes below 2,500
feet (762 meters) with the high altitude adjustment is not
recommended.
