FUEL AND OIL
FUEL REQUIREMENTS
Evinrude MFE models are designed to use
several different fuel types. Refer to Fuel Se-
lector Switch on page 14.
Heavy Fuels
Approved heavy fuels include:
• JP4, JP5, JP8
• Jet A, Jet B
• Kerosene
IMPORTANT: Evinrude/Johnson XD100 out-
board oil MUST be used when outboard is run
on heavy fuels. DO NOT use Diesel DFM-F76
or BioDiesel fuels. For combat emergency sit-
uations see Emergency Fuel on p. 13.
Gasoline
Use fresh, unleaded automotive gasoline with
the following octane rating:
Use unleaded gasoline that contains methyl
tertiary butyl ether (MTBE) ONLY if the MTBE
content does not exceed 15% by volume.
Emergency Fuel
In a combat emergency when no other fuel is
available, diesel DFM-F76 or BioDiesel can
be used. Operating time should be limited to
the duration of the combat emergency and
the operator should return to operating on one
of the approved fuels as soon as possible.
Idle and low speed operation (below 3000
RPM) should be avoided to prevent spark
plug fouling when operating on diesel DFM-
E76 or BioDiesel.
IMPORTANT: If the outboard MUST be run
on diesel, the de-carbon procedure MUST be
performed immediately after return from the
mission. Refer to De-Carboning Procedure
on p. 38.
Fuel Additives (gasoline only)
The only fuel additives approved for use are:
•
Evinrude/Johnson 2+4 Fuel Conditioner
• Evinrude/Johnson Fuel System Cleaner
Use of other fuel additives can result in
poor performance or engine damage.
Evinrude/Johnson 2+4 Fuel Conditioner will
help prevent gum and varnish deposits and
will remove moisture from the fuel system. It
can be used continuously and should be used
during any period when the outboard is not
being operated on a regular basis.
Evinrude/Johnson Fuel System Cleaner
helps keep fuel injectors in good condition.
A
WARNING
Gasoline is extremely flammable and
highly explosive under certain condi-
tions. Follow the instructions in this
section explicitly. Improper handling of
fuel could result in property damage,
serious injury or death.
Leaking fuel is a fire and explosion haz-
ard. All parts in the fuel system should
be inspected frequently and replaced if
signs of deterioration or leakage are
found. Inspect the fuel system each time
you refuel, each time you remove the
engine cover and annually.
Follow these instructions to ensure
safety when handing fuel:
• Always turn off the engine before fuel-
ing.
• Never permit anyone other than an
adult to refill the fuel tank.
• Do not fill the fuel tank all the way to
the top or fuel may overflow when it ex-
pands due to heating by the sun.
• Remove portable fuel tanks from the
boat before fueling.
• Always wipe off any fuel spillage.
• Do not smoke, or allow open flames, or
sparks or use electrical devices such
as cellular phones in the vicinity of a
fuel leak or while fueling.
Always work in a well ventilated area.
