FUEL
Fuel System-General Information
Gasoline Requirements- Use non-leaded gasoline with the following
minimum octane rating:
• Inside United States- See outboard manufacturer owner’s manual
since octane requirements are based on engine horsepower.
• Outside United States- See outboard manufacturer owner’s manual
since octane requirements are based on engine horsepower.
The use of leaded fuels can seriously damage the engine.
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.
Ethanol in fuel is a strong cleaning solvent that can clean fuel system
gum and varnish. As a trade off these released deposits can clogg fuel
system parts such as fi lters and engine fuel injectors.
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. This type of fuel can cause a loss of perfor-
mance, starting problems, serious fuel system and engine damage.
