Maintenance Schedule
Introduction

A Word Abouf Maintenance
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 GM
vehicles, maintenance needs vary. You may even need more
frequent checks and replacements than you will find in the
schedules in this part.
So please read this part and note how
you drive. If you have any questions on how to keep your
vehicle in good condition, see your Oldsrnobile dealer, the
place many GM owners choose to have their maintenance
work done. Your dealer can be relied upon to use proper
parts and practices.

How This Part is Organized
The remainder of this part is divided into five sections:
Section
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 dealer’s
service department or another qualified service center do
these jobs.
A
Performing maintenance work on a vehicle can 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. I
If you are skilled enough to do some work on your vehicle,
you will probably want to get the service information GM
publishes.
You will find a list of publications and how to get
them in this manual. See the
Index under Service
Publications.
Section B: Owner Checks & Services tells you what should
be checked whenever you stop for fuel. It also explains what
you can easily do to help keep your vehicle in good
condition.
Section C: Periodic Maintenance Inspections explains
important inspections that your Oldsmobile dealer’s service
department or another qualified service center should
perform.
Section
D: Recommended Fluids & Lubricants lists some
products GM recommends to help keep your vehicle
properly maintained. These products, or their equivalents,
should be used whether you
do the work yourself or have it
done.
Section
E: Maintenance Record provides a place for you to
record the maintenance performed
on your vehicle.
Whenever any maintenance is performed, be sure to write it
down in this section. This will help you determine when
your next maintenance should be done. In addition, it is a
good idea to keep your maintenance receipts. They may be
needed to qual@ your vehicle for warranty repairs.

Using Your Maintenance Schedules
This section tells you the maintenance services you should
have done and when you should schedule them. Your
Oldsmobile dealer lmows your vehicle best and wants you to

needs, you’ll know that GM-trained and supported service
people will perform the work using genuine GM parts.
These schedules are
for vehicles that:
carry passengers and cargo within recommended limits.
