Introduction
A Word About Maintenance
We at General Motors want to help you
keep your vehicle in good working
condition. But we don’t laow 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 Oldsmobile
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.
Your Vehicle and the Environmen
Proper vehicle maintenance not only
helps to keep your vehicle in good
working condition, but also helps the
environment. All recommended
maintenance procedures are important.
Improper vehicle maintenance or the
removal of important components can
significantly affect the quality of the air
we breathe. Improper fluid levels or
even the
wrong tire inflation can
increase the level
of emissions from
your vehicle.
To help protect our
environment, and to help keep your
vehicle in good condition, please
maintain your vehicle properly.
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. If
you are skulled 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
Service Publications
in the Index.
“Section B: Owner Checks and
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.
ProCarManuals.com

“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 qualify your
vehicle for warranty repairs.
Section A: Scheduled
Maintenance Services
Using Your Maintenance
Schedules
This section tells you the maintenance
services you should have done and
when you should schedule them. Your
Oldsmobile dealer knows 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
Certificatioflire label. See the
Index
under Loading Your Vehicle.

surfaces within legal driving limits.
