1 Section 6 Service-and Appearance Care
I-
Here you will find information about the care of your
Oldsmobile. This section begins with service and fuel
information, and then
it shows how to check important
fluid and lubricant levels. There is also technical
information about your vehicle, and a part devoted to its
appearance care.
Service
Your Oldsmobile retailer knows your vehicle best and
wants you to be happy with
it. We hope you’ll go to
your retailer for all your service needs. You’ll get
genuine GM parts and GM-trained and supported
service people.

We hope you’ll want to keep your GM vehicle all GM.
Genuine GM parts have one
of these marks:

Doing Your Own Service Work
If you want to do some of your own service work, you’ll
,want to get the proper Oldsmabile Service Manual.
It tells you much more about how to service your
Oldsmobile than this manual can.
To order the proper
service manual, see “Service and Owner Publications”
in the Index.
,Your vehicle has an air bag system. Before attempting to
do your own service work, see “Servicing Your Air
Bag-Equipped Oldsmobile” in the Index.
You.should keep a record
with all parts receipts and list
the mileage and the date
of any service work you
‘perform. See “Maintenance Record? in’the Index.

A CAUTION:
You can be injured and your ,vehicle could be
damaged
if you try to do service work on a
vehicle without knowing enough about it.

Be sure you have suffkient knowledge,
experience, and the proper replacement
parts and tools before you attempt any
vehicle maintenance task. Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”
fasteners can be easily confused.
If you use
the wrong fasteners, parts can later break
or fall
off. You could be hurt.

Use regular unleaded gasoline rated at 87 octane or
higher. At a minimum, it should meet specifications
ASTM D4814 in the United States and CGSB 3.5-M93
in Canada. Improved gasoline specifications have been
developed by the American Automobile Manufacturers
Association (AAMA) for better vehicle performance
and engine protection. Gasolines meeting the AAMA
-specification could provide improved driveability and
emission control system protection compared to
other gasolines.
Be sure the posted octane is at least 87. If the octane is
less than 87, you may get a heavy knocking noise when
you drive.
If it’s bad enough, it can damage your engine.
If you’re using fuel rated at 87 octane or higher and you
still hear heavy knocking, your engine needs service. But
don’t worry
if you hear a little pinging noise when you’re
accelerating or driving up a hill. That’s normal, and you d\
on’t
have to buy a higher octane fuel to get rid of pinging. It’\
s the
heavy, constant knock that means you have a problem. If your vehicle
is certified to meet California Emission
Standards .(indicated on the underhood tune-up label), it
is designed to .operate on fuels that meet California
specifications. If such fuels are not available in states
adopting .California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on
your instrument panel may turn on and/or your vehicle
may fail a smog-check test. If this occurs, return
to your authorized Oldsmobile retailer for diagnosis
to determine the cause of failure. In the event it is
determined that the cause of the condition is the type of
fuels used, repairs may not be covered by your warranty.
In Canada, some gasolines contain an octane-enhancing
additive called MMT. If you use such fuels, your
emission control system performance may deteriorate
and the malfunction indicator lamp on your instrument
panel may turn on. If this happens, return to your authorized Oldsmobile dealer for service.

To provide cleaner air, all gasolines are now required to
contain additives that will help prevent deposits from
forming in your engine and fuel system, allowing your
emission control system to function properly. Therefore,
you should not have to add anything to the fuel. In
addition, gasolines containing oxygenates, such as
ethers and ethanol, and reformulated gasolines may
be available in your area to help clean the air. General
Motors recommends that you use these gasolines if they
comply with the specifications described earlier.
NOTICE: ~~
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard
to find. Never use leaded gasoline
or any other fuel not
recommended in the previous text on fuel. Costly repairs
caused by use of improper fuel wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
You can also write us at the following address for
advice. Just tell us where you’re going and give your
Vehicle Identification Number (VIN).

Filling Your Tank The cap. is behind a hinged door on the left side of
your vehicle.
I A CAUTION:
Gasoline vapor is highly flammable. It burns
violently, and that can cause very bad injuries.
Don’t smoke
if you’re near gasoline or refueling
your vehicle. Keep sparks, flames, and smoking
materials away from gasoline.
While refueling, hang the
cap inside the fuel door.
To take off the cap, turn it slowly to the left
(counterclockwise).

I 1 CAUTIOT’
If you get gasoline on yourself and then
something ignites it, you could be badly burned.
Gasoline can spray out on you
if you open the
fuel filler cap too quickly. This spray can happen
if your tank
is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait for any “hiss” noise to stop. Then unscrew
the cap all the way.
Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon as possible. See “Cleaning the
Outside of Your Oldsmobile” in the Index. When you put the
cap back on,
turn it to the right until
you hear at least three clicks. Make sure you fully install
the cap. The diagnostic system can determine if the fuel
cap has been left off or improperly installed. This would
allow fuel to evaporate into the atmosphere. See
“Malfunction Indicator Lamp” in the Index.
NOTICE:
If you need a new cap, be sure to get the right
type. Your retailer can get one for you. If you get
the wrong type, it may not fit
or have proper
venting, and your fuel tank and emissions system
might be damaged.

Checking Things Under the Hood Hood Release
A CAUTION:
I
I
An electric fan under the hood can start up and
injure you even when the engine
is not running.
Keep hands, clothing and tools away from any
underhood electric fan.
Things that burn can get on hot engine parts and
start
a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or others
could be burned. Be careful not to drop
or spill
things that
will burn onto a hot engine.
To open the hood, first
pull the handle inside
the vehicle.
Then
go to the front of the
vehicle and release the
secondary hood release.
Lift the hood.

Engine Oil
Before closing the hood, be sure all the filler caps are
on properly. Then just pull the hood down and close
LOW OIL
LEVEL
,If the LOW OIL LEVEL
light on the instrument
panel comes on, it means
you need to check your
engine oil level right away.
For more information, see
“Low Oil Level Light” in the
Index. You should check your engine oil level regularly;
this is an added reminder.
It’s a good idea to check your engine oil after you get
fuel. In order to get an accurate reading, the oil must be
hot and the vehicle must
be on level ground.
