Fuel Recommendations - Honda BF40D Owner's Manual

SERVICING YOUR OUTBOARD MOTOR

FUEL RECOMMENDATIONS

Use unleaded gasoline with a pump
octane rating of 86 or higher.
Your outboard motor is certified to
operate on unleaded gasoline.
Unleaded gasoline produces fewer
engine and spark plug deposits and
extends exhaust system life.
Never use stale or contaminated
gasoline or an oil/gasoline mixture.
Avoid getting dirt or water in the fuel
tank.
You may use unleaded gasoline
containing no more than 10% ethanol
(E10) or 5% methanol by volume. In
addition, methanol must contain
cosolvents and corrosion inhibitors.
Use of fuels with content of ethanol
or methanol greater than shown
above may cause starting and/or
performance problems. It may also
damage metal, rubber, and plastic
parts of the fuel system.
82
Engine damage or performance
problems that result from using a fuel
with percentages of ethanol or
methanol greater than shown above
are not covered under warranty.
If your outboard motor will be used
on an infrequent or intermittent basis,
please refer to the fuel section of the
STORAGE chapter (p. 93

deterioration.
