Use regular unleaded gasoline rated at 87
octane or higher. It should meet
specifications ASTM D4814 in the
U.S.
and CGSB 3.5-92 in Canada. These fuels
should have the proper additives,
so you
should not have to add anything
to the
fuel.
In the U.S. and Canada, it’s easy to be
sure you get
the right kind of gasoline
(unleaded). 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.
If you’re using fuel rated at 87 octane or
higher and
you still hear heavy knoclung,
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 don’t have to
buy a higher octane fuel
to get rid of
pinging. 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.
NOTICE:
Fuel that is more than 5% methanol
is bad for your vehicle. Don’t
use it.
It can corrode metal. parts in yohs
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 problems.

Use premium unleaded gasoline rated at
91 octane
or higher. You may use middle
grade or regular unleaded gasolines, but
your vehicle may not accelerate as well.
The gasoline you use should meet
specifications ASTM D4814 in the
U.S.
and CGSB 3.5-92 in Canada. These fuels
should have the proper additives,
so you

right on the pump. And only unleaded
nozzles will fit into your vehicle’s filler
neck.
Be sure the posted octane for premium is
at least 91 (at least 89 for middle grade
and
87 for regular). 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.
If you’re using fuel rated at 91 octane or
higher and you still hear heavy knocking,
