NOTICE:
Fuel
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
In the pump. And only unleaded nozzles
will
fit into your vehicle’s filler neck.
Be sure the posted octane is at least 87.
:f the octane is less than 87, you may get
sl 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
D48 14 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.

(unleaded). You’ll see
UNLEADED right

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,
your engine needs service. But don’t

What about gasoline with blending
materials that contain oxygen, 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.
IC
NOTICE:
I
rue1 mat is more than 3% metha
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 I
rranty. And even at 5% or less,
there must be “cosolvents” and
corrosion preventers in this fuel
to
help avoid these problems.

Gasolines for Cleaner Air
Your use of gasoline with detergent
additives will help prevent deposits from
forming
in your engine and fuel system.
That helps keep your engine in tune and
your emission control system working
properly. It’s good for your vehicle, and
you’ll be doing your part for cleaner air.
Many gasolines are
now blended with
materials called oxygenates. General
Motors recommends that you use
gasolines
with these blending materials,
such as MTBE and ethanol.
By doing so,
you can help clean the air, especially in
those parts of the country that have high
carbon monoxide levels. In
addition, some gasoline suppliers are
now producing reformulated gasolines.
These gasolines are specially designed to
reduce vehicle emissions. General Motors
recommends that you
use reformulated
gasoline.
By doing so, you can help clean
the air, especially
in those parts of the
country that have high ozone levels.
You should ask your service station
operators
if their gasolines contain
detergents and oxygenates, and if they
have been reformulated to reduce vehicle
emissions.
