1993 PONTIAC GRAND-AM 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 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, 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.
I
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.
Fuel Capacity:
15.2 U.S. Gallons (57.5L). Use
unleaded fuel only.

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.
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.

Engine Oil
It’s a good idea to check your engine oil
every time you get fuel. In order to get
an accurate reading, the
oil must be
warm and the vehicle must be
on level
ground. Turn
off the engine and give the
oil a few minutes to drain back into the
oil pan. If you don’t, the oil dipstick
might not show the actual level.
To Check Engine Oil:
Pull out the dipstick and clean it with a
paper towel or cloth, then push
it back
in all the way. Remove it again, keeping
the tip lower.

When to Add Oil:
If the oil is at or below the ADD line,
then
you’ll need to add some oil. But
you must use the right kind. This
section explains what kind
of oil to use.

What Kind of Oil to Use
Look for Three Things:
SG
“SG” must be on the oil container,
either by itself or combined with other
quality designations, such as “SG/CC,” “SG/CD,”
“SF, SG, CC,”
etc. These letters show American
Petroleum Institute
(API) levels of
quality.

SAE 5W-30 (2.3L Quad OHC and
Quad 4 Engines)
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.
