3eginning midyear 1993, oils of the
)roper quality for your vehicle will be
dentified with this new “starburst”
;ymbol. The “starburst” symbol indicates
hat the
oil has been certified by the
imerican Petroleum Institute
(API), and
s preferred for use in your gasoline
‘ngine.
(ou should look for this on the front of
he oil container, and use only oils that
lisplay this new symbol.
(ou should also use the proper viscosity
Iil for your vehicle, as shown in the
ollowing chart:
I 80
Recommended SAE Viscosity
Grade Engine Oils
For best fuel economy and cold starting,
select the lowest
SAE viscosity grade oil
for the expected temperature range.

OILS ARE AVAILABLE, SAE 30

ANOTHER GRADE OIL NOT RECOMMENDED.
DO NOT USE SAE 1OW-40, SAE 2OW-50 OR
4s shown in the chart, SAE 5W-30 is best
or your vehicle. However,
you can use
;AE 1OW-30 if it’s going to be 0°F
- 18 “C) or above. These numbers on an
)il container show its viscosity, or
hickness.
Do not use other viscosity oils,
uch as
SAE low-40 or SAE 20W-50.

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 4 miles
(6 km).
It’s below freezing outside and most
trips are less than
10 miles ( 16 km).
The engine is at low speed most of the
time (as
in door-to-door delivery, or
in stop-and-go traffic).
You tow a trailer often.
Most trips are through dusty places.
[f any one of these is true for your
Vrehicle, then you need to change your oil
md filter every 3,000 miles (5 000 km) or-
3 months -- whichever comes first.
[f none of them is true, change the oil
=very 7,500 miles (12 500 km,) or
12 months -- whichever comes first.
Change the filter at the first oil change
and at every other
oil change after that.
Engine Coolant Heater
(Engine Block Heater)
An engine coolant heater can be a big
help if
you have to park outside in very
cold weather,
0°F (- 18OC) or colder. If
your vehicle has this option, see “Engine
Coolant Heater” (Engine Block Heater)
in
the Index.
What to Do with Used Oil
lid you know that used engine oil
:ontains certain elements that may be
Inhealthy
for your skin and could even
:awe cancer? Don’t let used oil stay on
your skin for very long. Clean your skin
md nails with soap and water, or a good
land cleaner. Wash or properly throw
lway clothing or rags containing used
mgine oil. (See the manufacturer’s
warnings about the use and disposal of oil
products.)
Used oil can be a real threat to the
mvironment.
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.

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 a Pontiac Dealership 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.
NOTICE:
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,
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.
0 While pulling a trailer.
To get the right reading, the fluid should
,e at normal operating temperature,
which is 180°F to 200°F (82°C to 93°C).
Set the vehicle warmed up by driving
ibout 15 miles
(24 km) when outside
iemperatures are above
50°F (10°C). If
it’s colder than 50°F
(IOOC), you may
have to drive longer.
To Check the Fluid Level
1. Keep the engine running. Park your
vehicle on a level place. Keep the
engine running.
2. With the parking brake applied, place
the shift lever in PARK (P).
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 for three to
five minutes.

the engine
oil is changed. However, the
tluid
in your manual transaxle doesn't
require changing.
How to Check
Because this operation can be a little
diftlcult,
you may choose to have this done
at a Pontiac Dealership Service Department.

the instructions here, or you could get a
false reading on the dipstick.
NOTICE:
Too much or too little tluid can
darnage
your transaxle. Too much
can mean that some
of the tluid
could come out and fall
011 hot
engine parts or exhaust system,
starting a fire. Be sure
to get an
accurate reading
if you check your
transaxle fluid.
Check the tluid level only when your
engine IS off. the vehicle is parked on a
level place and the transaxle is
cool
enough for you to rest your fingers on the
transaxle case.
I
hen, Follow These Steps:
I Flip the handle up and the.n pull out
the dipstick and clean it with a rag or
paper towel.
2. Push it back in all the way and remove
It.
3. Check both sides of the dipstick and
read the lower level. The fluid level
must be between the
ADD and FULL
marks. (Note: Fluid may appear at the
bottom
of the dipstick even when the
tluid level is several pints low.)
4. If the tluid level is where it should be,
push the dipstick back in all the way
and flip the handle down. If the fluid
level is low. add more fluid as
described
in the next steps.

How to Add Fluid
Here’s how to add fluid. Refer to the
Maintenance Schedule to determine what
kind of fluid
to use. See “Recommended
Fluids and Lubricants”
in the Index.
1. Remove the dipstick by flipping the
handle up and then pulling the
dipstick out.
2. Add fluid at the dipstick hole.
Add only enough fluid to bring the
fluid level up to the
FULL mark on the
dipstick.
3. Push the dipstick back in all the way;
then flip the handle down to lock the
dipstick
in place.
Hydraulic Clutch
The hydraulic clutch in your vehicle is
self-adjusting. The clutch master cylinder
reservoir is filled with hydraulic clutch
fluid.
It isn’t a good idea to “top off’ your
clutch fluid. Adding fluid won’t correct a
leak.
A fluid loss in this system could indicate
a problem. Have the system inspected and
repaired.
When to Check and What
to Use
Refer to the Maintenance Schedule to
determine how often you should check
the fluid level
in your clutch master
cylinder reservoir and for the proper fluid.
See “Owner Checks and Services” and
“Recommended Fluids and Lubricants”
in
the Index.

How to Check:
The proper fluid should be added if the
level is at or below the STEP mark on the
reservoir cap. See the instructions on the
reservoir cap.
Engine Coolant
The following explains your cooling
system and how to add coolant when
it is
low.
If you have a problem with engine
overheating, see “Engine Overheating”
in
the Index,
The proper coolant for your Pontiac will:
Give freezing protection down to
-34°F (-37°C).
Give boiling protection up to 262°F
( 128 “C).
Protect against rust and corrosion.
Help keep the proper engine
temperature.
Let the warning lights work as they
should.
What to Use
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze that meets “GM Specification
1825-M,” which won’t damage aluminum
parts.
You can also use a recycled coolant
conforming to GM Specification 1825-M
with a complete coolant flush and refill. If
you use this mixture, you don’t need to
add anything else. NOTICE:
If you use an improper coolant mix,
your engine could overheat and be
badly damaged. The repair cost
wouldn’t be covered by your
warranty. Too much water
in the
mix can freeze and crack the engine,
radiator, heater core and other parts.
