Index
Here’s an alphabetical listing of almost every subject in this manual. You can use it to quickly find
something you want to read.

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 2OW-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst” symbol. Failure
to use the
recommended
oil can result in engine damage not
covered
by your warranty.
GM Goodwrench@ oil meets all the requirements for
your vehicle.
If you are in an area where the temperature falls below
-20°F (-29”C), consider using either an SAE 5W-30
synthetic oil or an
SAE OW-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Don’t add anything to your oil. Your retailer is ready to
advise
if you think something should be added.
When to Change Engine Oil
If any one of these is true for you, use the short tripkity
maintenance schedule:
0
0
0
0
0
Most trips are less than 5 to 10 miles (8 to 16 h).
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.
You frequently tow a trailer
or use a carrier on top of
your vehicle.
The vehicle
is used for delivery service, police, taxi
or other cornmercial application.
Driving under these conditions causes engine oil to
break down sooner. 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
occurs first.
6-15

If none of them is true, use the long triphighway
maintenance schedule. Change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
occurs first. Driving a vehicle with a fully warmed
engine under highway conditions causes engine oil
to
break down slower.
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 retailer, a service station or a local recycling
center for help.
The air cleaner is located on the driver’s side of the
engine compartment.
To check or replace the air filter:
1. Unscrew the four Phillips-head screws, then pull the
cover back.
2. Remove the air cleaner filter.
3. Be sure to install the air cleaner filter and replace the
cover tightly.
6-16

Refer to the Maintenance Schedule to determine when to
replace the air filter.
See “Scheduled Maintenance Services” in the Index.
Operating the engine with the air cleaner off can
cause you or others to be burned. The air cleaner
not
only cleans the air, it stops flame if the engine
backfires.
If it isn’t there, and the engine
backfires, you could be burned. Don’t drive with
it off, and be careful working on the engine with
the air cleaner off.
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.
Automatic Transaxle Fluid
It is not necessary to check the transaxle fluid level. A
transaxle fluid leak is the only reason for fluid loss. If a
leak occurs, take the vehicle to your Oldsmobile retail
facility Service Department and have it repaired as soon
as possible. You may also have your fluid level checked
by your retailer or service center when you have your oil changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city h.aff.3~ where the outside temperature
0 In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.

You can’t tell if your tires are properly inflated
lsimply by looking at them. Radial tires may look properly inflated even when they’re underinflated.
@e sure to put
the valve caps back on the valve
’stems. They help prevent leaks by keeping out
dirt
and moisture.
Tire Inspection and Rotation
Tires should be rotated every 6,000 to. 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your
tires as soon as possible and check
wheel alignment.
Also check for damaged tires or
wheels. See “When It’s Time for New Tires” and
“Wheel Replacement” later
in this section for
more information.
The purpose
of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the myst important.
See “Scheduled
Maintenance Services” in the Index for scheduled
rotation intervals.

How This Section is Organized
The remainder of this section is divided into five parts:
“Part A: Scheduled Maintenance Services’’ shows
what
to have done and how often. Some of these
services can be complex,
so unless you are technically
qualified and have the necessary equipment, you should
let your retailer’s service department or another
qualified service center
do these jobs.
be dangerous. In trying to do some jobs, you can
be seriously injured.
Do your own maintenance
work only if you have the required know-how
and the proper tools and
equipment for the job.
If you have any doubt, have a qualified
technician do the work.
If you are skilled enough to do some work on your
vehicle, you will probably want to get the service
information. See “Service and Owner Publications” in
the Index.

Part A: Scheduled Maintenance
Services
Using Your M ’,--lawe Schedule
We at General Motors want to help you keep your
vehicle in good working condition. But we don’t know
exactly how you’ll drive it. You may drive very short
distances only a few times a week. Or you may drive
long distances all the time in very hot, dusty weather.
You may use your vehicle in making deliveries. Or
you may drive it to work, to do errands
or in many
other ways.
Because of all the different ways people use their
vehicles, maintenance needs
vary. You may even need
more frequent checks and replacements than you’ll find
in the schedules in this section.
So please read this
section and note how you drive. If you have any
questions on how to keep your vehicle in good
condition, see your retailer.
This part tells you the maintenance services you should
have done and when you should schedule them. If you go to your retailer for your service needs, you’ll
know
that GM-trained and supported service people will
perform the work using genuine
GM parts. The proper fluids and lubricants to
use are listed in Part D.
Make sure whoever services your vehicle uses these. All
parts should be replaced and all necessary repairs done
before you
or anyone else drives the vehicle.
These schedules are for vehicles that:
carry passengers and cargo within recommended
limits. You will find these limits on your vehicle’s
Tire-Loading Information label. See “Loading Your
Vehicle” in the Index.
0 are driven on reasonable road surfaces within legal
driving limits.
0 use the recommended fuel. See “Fuel” in the Index.
Selecting the Right Schedule
First you’ll need to decide which of the two schedules is
right for your vehicle. Here’s how to decide which
schedule to follow:
7-4

Maintenance Schedule
I Short TripKity Definition I
Follow the Short TripKity Maintenance Schedule if any
one of these conditions
is true for your vehicle:

Most trips include extensive idling (such as fiequent
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 vehicle.
If the vehicle is used for delivery service, police, taxi
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down soonex
