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.)
3800 Engine (Code L):
Use regular unleaded gasoline rated at 87
octane or higher. It 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. 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
mgine.
[f 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.
3800 Supercharged Engine (Code 1):
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.
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 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 9
1 octane or
higher and you still hear heavy knacking,
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?
ProCarManuals.com

Service & Appearance Care
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 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 problems.
Gasolines for Cleaner Air
Your use of gasoline with deposit control
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
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 deposit
control additives and oxygenates, and if
they have been reformulated to reduce
vehicle emissions.
r
Countries
If you plan on driving in another country
outside the
U.S. or Canada, unleaded fuel
may ‘be hard to find.
Do not use leaded
gasoline. If you use even one
tankful, your
emission controls won’t work well
or at
all. With continuous use, spark plugs can
get fouled, the exhaust system can corrode,
and your engine
oil can deteriorate quickly.
Your vehicle’s oxygen sensor
will be
damaged. All of that means costly repairs
that wouldn’t be covered by your warranty.
To check on fuel availability, ask an auto
club,
or contact a major oil company that
does business
in the country where you’ll
be driving.
