1993 PONTIAC GRAND-PRIX fuel additives

Fuel
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.
Fuel Capacity:
16.5 U.S. Gallons (62 L) . Use unleaded
fuel only.
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.
Fuel that is more than
5%
methanol is bad for your vehicl
Don’t use
it. It can corrode me
parts in your fuel system and a
damage plastic and rubber parts.
That damage wouldn’t be covered
under your warranty. And ev
5% or less, there must be
“cosolvents” and corrosion

Service 4S Appearance Care
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.
214
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.
Fuels in Foreign 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.

Service & Appearance Care
For best fuel economy and cold startin
select the lowest
SAE viscosity grade oil
for the expected temperature range.
..I
Wbat Kind of Oil to Use (CONT.)
SAE 5W-30
As shown in the viscosity chart, SAE
5W-30 is best for your vehicle.
However, you can use
SAE 1OW-30 if
it’s going to be 0°F (-18°C) or above.
These numbers on an
oil container
show its viscosity, or thickness.
Do not use other viscosity oils such as
SAE 1OW-40 or SAE 20W-50.

IF NEITHER SAE 5W-30 NOR SAE 1OW-30
GRADE
OILS ARE AVAILABLE, SAE 30
GRADE MAY BE USED AT TEMPERATURES
ABOVE
40 DEGREES F (4 DEGREES C).
DO NOT USE SAE 1OW-40, SAE 2OW-50 OR
