CHECK
OIL
If the CHECK OIL light on the instrument panel comes
on,
it means you need to check your engine oil level
right away. For more information, see
“CHECK OIL
Light” in the Index. You should check your engine oil
level regularly; this is an added reminder.
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.
2.3 L Engine Oil Dipstick

3.1 L V-6 Engine Oil Dipstick
The engine oil dipstick handle is yellow. The dipstick on
the
2.3L L-4 engine is located on the rear of the engine.
The dipstick on the
3.1L V-6 engine is located on the
front of the engine behind the fan.
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 down, and check the level.

3.1L V-6: Adding Oil 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
part explains what kind of oil to use. For crankcase
capacity, see “Capacities and Specifications” in the
Index.
NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.
Just fill it enough to put the level somewhere in the
proper operating range. Push the dipstick all
the way
back in when
you’re through.

What Kind of Oil to Use
Oils of the proper quality for your vehicle can be
identified by looking for the “Starburst” symbol. The
“Starburst” symbol indicates that the oil has been
certified by the American Petroleum Institute
(API), and
is preferred for use in your gasoline engine.
Beginning midyear 1993, oils of the proper quality for
your vehicle will be identified with this
new “starburst”
symbol. The “starburst” symbol indicates that the oil has
been certified by the American Petroleum Institute
(MI), and is preferred for use in your gasoline engine.
If you change your own oil, be sure you use oil that has
the “Starburst” symbol on the front of the oil container.
If you have your oil changed for you, be sure the oil put
into your engine is American Petroleum Institute
certified for gasoline engines.
You should also use the proper viscosity oil for your
vehicle,
as shown in the following chart:

DO NOT USE SAE ZOW-50 OR ANY OTHER GRADE OIL NOT RECOMMENDED
As shown in the 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 20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst” symbol. Failure to use the proper oil
can result in engine damage not covered by your
warranty.
GM Goodwrench’ oil (in Canada, GM Engine Oil)
meets all the requirements for your vehicle.
Engine Oil Additives
Don’t add anything to your oil. Your Pontiac dealer is
ready to advise if you think something should be added.

When to Change Engine Oil
See if any one of these is true for you:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop and go traffic).
0 Most trips are through dusty areas.
0 You frequently tow a trailer or use a carrier on top of
your car.
If any one of these is true for your vehicle, then you
need to change your oil and filter every
3,000 miles
(5 000 km) or 3 months -- whichever comes first.
If none of them is true, change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
comes first.
Engine Coolant Heater
An engine coolant heater can be a big help if you have
to park outside in very cold weather,
0 OF (- 18 O C) or
colder.
If your vehicle has this option, see “Engine
Coolant Heater” in the Index.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t let used oil stay on your skin
for
very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about the use and disposal
of oil products.)
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t ever dispose of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it
to a place that collects used oil. If
you have a problem properly disposing
of your used oil,
ask your dealer, a service station or a local recycling
center for help.

Air Cleaner
Refer to the Maintenance Schedule to determine when to
replace the air filter.
See “Scheduled Maintenance Services” in the Index.
NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner in place when you’re driving.

Air Filter Replacement
1. Remove the screws on the housing cover and pull the
cover back.
2. Remove the air cleaner filter.
3. Install the replacement air cleaner filter and replace
the cover.
4. Tighten screws on the air filter cover.
Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil
is changed. Refer to the
Maintenance Schedule to determine when to change
your fluid. See “Scheduled Maintenance Services” in the
Index.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at your Pontiac dealer Service
Department.
If you do it yourself, be sure to follow all the instructions
here, or you could get
a false reading on the dipstick.
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come out and fall on hot engine parts
or exhaust system parts, starting a fire. Be sure to
get an accurate reading if
you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level if you have been driving:
0 When outside temperatures are above 90°F (32” C).
0 At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
While pulling a trailer.

To get the right reading, the fluid should be at normal
operating temperature, which
is 180°F to 200°F (82°C
Get the vehicle warmed up by driving about
15 miles (24
h) when outside temperatures are above 50°F (10°C). If
it's colder than 50 "F ( 10 "C), you may have to drive longer.

To check the fluid level
1. Park your vehicle on a level place. Keep the engine
running.
in PARK (P).
2. With the parking brake applied, place the shift lever
3. With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds in each range. Then, position the shift
lever in PARK
(P).
4. Let the engine run at idle €or three to five minutes. Then, without shutting
off the engine, follow these steps:
The automatic transaxle dipstick handle is red. Pull out
the dipstick and wipe it with a clean rag
or paper towel.
1. Push it back in all the way, wait three seconds and
then pull it back out again.
2. Check both sides of the dipstick, and read the lower
level. The fluid level must be in the cross-hatched
area.
3.
If the fluid level is in the acceptable range, push the
dipstick back in all the way.
