The 8th digit of your Vehicle
Identification Number (VIN) shows the code letter for your engine. You will
find the VIN at the top left of your
instrument panel. (See “Vehicle
Identification Number” in the Index.)
3.4L L32 (Code S)
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 knocking,
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.
5.7L LT1 (Code P)
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
should not have to add anything to the
fuel. [n

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.

higher and you still hear heavy knocking,
