Engine Oil Additives
Don’t add anything to your oil. Your Oldsmobile retailer
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 krn).
This
is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving
in stop-and-go traffic).
Most trips are through dusty areas.
0 You frequently tow a trailer or use a carrier 011 top of
your vehicle.
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 I2 months -- whichever
comes first.
Engine Coolant Heater (Option)
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”
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 or by 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 retailer, a service station or a local recycling
center for help.

Automatic Transaxle Fluid
When to Check and Change
The automatic transaxle fluid dipstick for the 3.1 L V6
engine is located near the center of the engine
compartment, to the left
of the windshield washer fluid
reservoir. The dipstick for
the 3800 V6 engine is located
toward the back
of the engine Compartment, near the
center. The dipstick handle (for both engines) has
a
bright, red loop design for easier identification.
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 Oldsmobile retailer
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 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:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
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 to 93°C).
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above 50°F
(10°C).
If it’s colder than 50°F (lO°C), you may have
to drive longer.

2. Push it back in all the way, wait three seconds and
paper towel.
then pull it back out again.
How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind
of transaxle fluid to use. See “Recommended
Fluids and Lubricants”
in the Index.

3. Check both sides of the dipstick, and read the lower
level.
The fluid level must be in the cross-hatched area.
4. If the fluid level is in the acceptable range, push the
dipstick back
in all the way.
If the fluid level is low, add only enough of the proper
fluid to bring the level into the cross-hatched area
on the
dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the
dipstick hole to bring it to the proper level. It doesn’t
take much fluid, generally less than
a pint (OSL).
Don’t overfill. We recommend you use only fluid
labeled DEXRON@-111, because fluid with that label
is made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON@-I11
is not covered by your new vehicle warranty.
0 After adding fluid, recheck the fluid level as
described under “How to Check.”
When the correct fluid level is obtained, push the
dipstick back in all the way.

How To Check Power Steering Fluid
When the engine compartment is cool, unscrew the cap
and wipe the dipstick with
a clean rag. Replace the cap
and completely tighten
it. Then remove the cap again
and look at the fluid level
on the dipstick.
The level should be at the
FULL COLD mark. Add
enough fluid to bring the level up to the mark.
A fluid loss in this system could indicate a problem.
Have the system inspected and repaired.
What to Add
Refer to the Maintenance Schedule to determine what
kind
of fluid to use. See ‘‘Recommended Fluids and
Lubricants”
in the Index.
Windshield Washer Fluid
To Add

leaks and damage hoses and seals.
The windshield washer fluid reservoir is located on the
driver’s side of the vehicle, toward the front
of the
engine compartment.

directions
on the container label.
Use suds only and apply with a clean sponge.
Don’t saturate the material.
Don’t rub it roughly.
As soon as you’ve cleaned the section, use a sponge
to remove the suds.
Rinse the section with a clean, wet sponge.
Wipe off what’s left with a slightly damp paper towel
or cloth.
Dry it immediately with a blow dryer or a heat lamp.
NOTICE:

Gently scrape excess soil from the trim material with
a clean, dull knife or scraper. Use very little cleaner,
light pressure and clean cloths (preferably
cheesecloth). Cleaning should start at the outside of
the stain, “feathering” toward the center. Keep
changing
to a clean section of the cloth.
When you clean a stain from fabric, immediately dry
the area with a blow dryer to help prevent a cleaning
ring. (See the previous NOTICE.)

Cleaning the Outside of Your
Oldsmobile
The paint finish on your vehicle provides beauty, depth
of color, gloss retention and durability.
Washing Your Vehicle
The best way to preserve your vehicle’s finish is to keep
it clean by washing it often with lukewarm or cold water.
Don’t wash your vehicle
in the direct rays of the sun.
Don’t use strong soaps or chemical detergents. Use
liquid hand, dish or car washing (mild detergent) soaps.
Don’t use cleaning agents that are petroleum based, or
that contain acid or abrasives.
All cleaning agents
should be flushed promptly and not allowed to dry on
the surface, or they could stain. Dry the finish with a
soft, clean chamois or a
100% cotton towel to avoid
surface scratches and water spotting.
Before entering an automatic car wash, if your vehicle is
equipped with the optional power sliding
door, be sure
to have the enable switch
in the OFF position.
High pressure car washes may cause water to enter your
vehicle.
Finish Care
Occasional waxing or mild polishing of your
Oldsmobile by hand may be necessary to remove
residue from the paint finish.
You can get GM approved
cleaning products from your retailer. (See “Appearance
Care and Materials”
in the Index.)
Your Oldsmobile has a “basecoatklearcoat” paint finish. The
clearcoat gives more depth and gloss to the colored basecoat.
Always use waxes and polishes that are non-abrasive and
made for a basecoatklearcoat paint finish.
NOTICE:
Machine compounding or aggressive polishing on
a basecoatklearcoat paint finish may dull the
finish or leave swirl marks.
Foreign materials such as calcium chloride and other
salts, ice melting agents, road oil and tar, tree
sap, bird
droppings, chemicals from industrial chimneys, etc. can
damage your vehicle’s finish
if they remain on painted
surfaces. Wdsh the
vehicle as soon as possible. If
necessary, use non-abrasive cleaners that are marked
safe for painted surfaces to remove foreign matter.
