uel is the lifeblood of your M17
decon. If the M17 runs out of fuel, it
won’t run until you refuel. But if it has
the wrong fuel, it may never run again.
So, if you remember nothing else,
remember the M17 engine takes only
MOGAS mixed with oil. Other fuels
or MOGAS with no oil can ruin the
engine.
But that’s not all. Different M17
models take different gas/oil mixtures.
The older M17 and M17A1 that have
not been upgraded with the Cuyana
engines take 1
quart
of two-cycle oil
per 5 gallons of MOGAS. The M17A2
and M17A3 take 1
pint
per 5 gallons.
How do you keep these fuel require-

But shaking
builds up
pressure in the
can, so unscrew
the lid slowly to
vent the can and
make sure fuel
doesn’t spray
everywhere.

their can tops black. Operators know
immediately which can they need.
If you’re ever unsure if you’ve added
oil to the MOGAS, use that fuel for
the burner. It runs on any fuel.
TM 3-4230-218-12&P says it’s OK
to substitute 30W oil for two-cycle oil
in an emergency
, such as when you’re
dealing with an actual chemical
agent, but that’s the only time. The 30W
builds up carbon in the engine.
Fuel and oil will separate in the can
if they sit very long. So before you put
the fuel line in the can, shake the can
to mix them again. Otherwise, the en-
gine won’t get lubed.
Second, color-code all fuel cans. Al-
most all M17 and M17A1s have silver
fan guards. Paint the tops of their cans
silver or white. The M17A2 and
M17A3 have black guards, so paint
ments straight if you have different
M17 models of decon units in your
outfit? First, paint ENGINE: TWO-
CYCLE MOGAS ONLY on the fuel

cans for the engine. That’s a good idea
even if all your M17s are the same
model.
