maintenance Oldsmobile Achieva 1995 s User Guide

Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
( 10 000 to 13 000 km) for any signs of unusual wear. If
unusual wear is present, 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 most important. See “Scheduled
Maintenance Services” in the Index for scheduled
rotation intervals.

Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material to
the parts repaired or
replaced to restore corrosion protection.
Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away. Bare metal will corrode
quickly and may develop into a major repair expense.
Minor chips and scratches can be repaired with touch-up
materials available from your retailer or other service
outlets. Larger areas of
finish damage can be corrected
in your retailer’s body
and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect
on the underbody. If these are not
removed, accelerated corrosion (rust) can occur on
the
underbody parts such as fuel lines, frame, floor pan, and
exhaust system even though they have corrosion
protection.
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where mud
and other debris can collect. Dirt packed in closed areas
of the frame should be loosened before being flushed.
Your retailer or an underbody vehicle washing system
can do this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall upon and
attack painted surfaces on your vehicle. This damage
can take two forms: blotchy, ringlet-shaped
discolorations, and small irregular dark spots etched into
the paint surface.
Although no defect
in the paint job causes this,
Oldsmobile will repair, at no charge
to the owner, the
surfaces of new vehicles damaged by this fallout
condition within
12 months or 12,000 miles (20 000 km)
of purchase, whichever comes first.

1 Section 7 Maintenance Schedule
I
IMPORTANT:
KEEP ENGINE OIL
AT THE PROPER
LEVEL AND CHANGE AS
RECOMMENDED
I
This section covers the maintenance required for your
Oldsmobile. Your vehicle needs these services to retain
its
safety, dependability and emission control performance.
I Plan I
Introduction
Your Vehicle and the Environment
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.
7-1

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.
If you are skilled enough to do some work on your
vehicle, you
will probably want to get the service
information
GM publishes. See “Service Publications”
in the Index.
“Part 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.
“Part C: Periodic Maintenance Inspections” explains
important inspections that your Oldsmobile retailer’s
service department or another qualified service center
should perform.
“Part D: Recommended Fluids and 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.
“Part 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 part. 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.

Part A: Scheduled Maintenance
Services
Using Your Maintenance 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 GM
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 Oldsmobile 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.
are driven on reasonable road surfaces within legal
driving limits.
use the recommended unleaded 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:

Maintenance Schedule

driving
in stop and go traffic).
0 Most trips are through dusty areas.

your vehicle. (With some models, you should never

all recommended maintenance services be performed at
the indicated intervals and the maintenance be recorded.
