Fuel
Use regular unleaded gasoline rated at 87 octane or
higher. It should meet specifications ASTM D4814 i.n
the United States and CGSB 3 5 9 2 in Canada. These
hels should have the proper additives,
so
you should not
have to add anything to the fuel.
h
the United States and Canada, it's easy to be sure you
get the right kind of gasoline (unlea.ded). You.'ll see
UNLEADED right on the pump. And only unleaded
nozzles will fit into your vehicle's filler neck.
Be sure the posted octane is at least 87. If the octane is
less than 87, you may get a heavy knocking noise when
you drive. If it's bad enough, it can damage your engine.
Lf
you're using fuel rated at 87 octane or higher and you
still hear heavy hocking, your engine needs service.
But don't worry if you hear a little pinging noise when
you're accelerating or driving up a hill. That's normal,
and you dan't have to buy a higher octane fuel to get rid
of pinmg. It's the heavy, constant knock that means
you have a problem.
What about gasoline with blending materials that
contain oxygen (oxygenates), such
as MTBE
or alcohol?
MTBE is "methyl tertiary-butyl ether." Fuel that is no
more than
15%
MTBE is
fine for
your vehicle.
Ethanol is ethyl or grain alcohol. Properly-blended fuel
that is no more than 10% ethanol is fine for your
vehicle.
Methanol is methyl or wood alcohol.
Fuel that is more than 5% methanol is bad for
your vehicle. Don't use it. It can corrode metal
parts
in
your fuel system and also damage plastic
and rubber parts, That damage wouldn't be
covered under your warranty. And even at
5 % or
less, there must be "cosolvents'' and corrosion
preventers
in
this fuel to help avoid these
