Fuel System

Octane Requirements

Use unleaded gasoline with the following minimum
octane rating:
• In the U.S.: (R+M)/2 (AKI) - 87
• Outside the U.S.: (RON) - 90
NOTICE! Engine damage resulting from the use of
lower octane gasoline (below 87 AKI or 90 RON) is
considered misuse of the engine and is not covered by
the warranty.
All Volvo Penta gasoline engines are engineered to
operate on AKI 87 (RON 90) octane fuel. Mid-grade
and premium fuels contain injector cleaners and other
additives that protect the fuel system and provide
improved performance. EFI engines may obtain an
increase in power from higher octane fuels.
NOTICE! Leaded gasoline may be available in some
markets. Leaded gasoline will damage the catalysts
and can not be used in engines with catalytic
converters. Catalyst failure due to improper fuel is not
covered by the warranty.

Ethanol-Blended Gasoline

Volvo Penta gasoline engines are designed to operate
on the commercially available ethanol-blended
gasoline approved by the legislation and governmental
agencies of all countries where the engines are
marketed and sold.
NOTICE! Do not use ethanol blends that contain a
higher percentage of ethanol than gasoline, such as
E85 (85% ethanol) or E98. Volvo Penta engines are
not designed to run on high percentages of ethanol.
Loss of performance will occur. Engine damage may
also occur; damage caused by fuel with too high a
percentage of ethanol is not covered by warranty.
Regardless of the ethanol content, the fuel must meet
the octane requirements stated above.
