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.

Maintenance Schedule
Section A: Scheduled Maintenance Services
290
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
be happy with it. If you go to your dealer for your service
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.
You will find these limits on your vehicle’s Tire-Loading
Information label. See the
Index under Loading Your
Vehicle.

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:

Maintenance Schedule

MAINLY driven under one or more of
the following conditions:

temperatures remain below freezing.
When most trips include extended
idling and/or frequent low-speed

+k An Emission Control Service.
12 The U.S. Environmental Protection Agency has
determined that the failure to perform this
maintenance item will not nullify the emission

completion of vehicle useful life. General

maintenance services be performed at the
indicated intervals and the maintenance be
recorded in Section
E: Maintenance Record.
