Fuel System-General Information
Gasoline Requirements- Use non-leaded gasoline with the following
minimum octane rating:
• Inside United States- (R+M)2 (AK)- 87
• Outside United States- (RON) -90
The use of leaded fuels will damage the catalysts and can not be used
with catalytic converters.
Gasoline in the United States and other areas is blended with 10%
ethanol and is known as E-10 at the pumps. Marine engines used in
your Regal boat may be operated with gasoline blended with no more
than 10% ethanol and that meets the minimum octane specifi cation.
Do not use ethanol blends greater than 10% such as a newer blend for select
motor vehicles called E-15. Your marine engine may be damaged by
more than 10% ethanol. A loss of performance may occur and the
engine may not be covered by the engine manufacturer’s warranty.
