Oxygenated fuel
Oxygenated fuel is gasoline that is mixed with alcohol or
an ether compound. Some areas use oxygenated fuel to
decrease emissions. The fuel must not contain more than
the given percentages of these oxygenates:
• Ethanol: 27% by volume.
• MTBE: 15% by volume.
• Methanol: 5% by volume.
CAUTION: Fuel that contains methanol must also
contain cosolvents and corrosion inhibitors as
protection for the fuel system.
CAUTION: Oxygenated fuel that contains more
than the given percentages of these oxygenates
voids the warranty. The engine performance can
decrease and the engine can become damaged.
