Adding Equipment to the Outside of
Your Oldsmobile
Things you might add to the outside of your vehicle can
affect the airflow around
it. This may cause wind noise
and affect windshield washer performance. Check with
your Oldsmobile retailer before adding equipment to the outside of your vehicle.
Fuel
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
(MA) 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 don’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.

Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadlenyl manganese tricarbonyl
(MMT);
ask your service station operator whether or not his fuel
contains MMT. General Motors does not recommend the
use of such gasolines.
If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance may be affected. The
malfunction indicator lamp on your instrument panel
may turn on. If this occurs, return to your authorized
Oldsmobile retailer for service.
To provide cleaner air, all gasolines
in the United States
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).

Engine Oil
It’s a good idea to check your engine oil every time you
get fuel.
In order to get an accurate reading, the oil must
be warm and the vehicle must be
on level ground.
The oil dipstick is a
yellow ring.
Turn off the engine and give
the
oil a few minutes to
drain back into the oil pan.
If you don’t, the oil dipstick
might not show the
actual level.

Operating the enge with the air cleaner off can
cause you or others to be burned. The air cleaner
not only cleans the air, it stops flame
if the engine
backfires. If it isn’t there, and the engine
backfires, you could be burned. Don’t drive with
it
off, and be careful working on the engine with
the air cleaner
off.
NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner
in place when you’re driving.
Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the
fluid and filter every 50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more
of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
0 When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
See “Scheduled Maintenance Services“
in the Index.

How to Check
Because this operation can be a little difficult, you ]nay
choose to have this done at your Oldsmobile retailer
Service Department.
If you do it yourself, be sure to follow all the
instructions here.
or you could get a false reading on
the dipstick.
NOTICE:
Too much or too little fluid can damage your
transmission.
Too much can mean that some of
the fluid could come out and fall on hot engine
parts or exhaust system parts, starting
a fire. Be
sure t.o get an accurate reading if you check your
transmission fluid.
Wait at least 30 minutes before checking the
transmission fluid level
if you have been driving:
0 When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is 180°F to
200°F
(82°C to 93°C).
Checking Transmission Fluid Hot
Get the vehicle warmed up by driving about 15 miles
(24 knl) when outside temperatures are above 50°F
(10°C). If it's colder than 50°F
(lO"C), drive the
vehicle
in THIRD (3) until the engine temperature gage
moves and then remains steady for
IO minutes. Then
follow the hot check procedures.
ProCarManuals.com

Checking Transmission Fluid Cold
A cold check is made after the vehicle has been sitting
for eight hours or more
with the engine off and is used
only as a reference. Let the engine run at idle for five
minutes if outside temperatures are 50°F
(10°C) or
more. If it's colder than
50°F (IO'C), you may have to
idle the engine longer. Should the fluid level be
low
during a cold check, you must perform a hot check
before adding fluid. This will give
you a more accurate
reading
of the fluid level.

1 NOTICE:
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix
will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you or
others could be burned. Use a
50150 mix of clean
water and
DEX-COOL TM coolant.
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered by your
warranty.
Too much water in the mix can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your retailer check your
cooling system.
NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.

Checking Coolant
When your engine is cold, the coolant level should be at
ADD, or a little higher. When your engine is warm, the
level should be up to
FULL HOT, or a little higher.
Adding Coolant
If you need more coolant, add the proper coolant
mixture at the coolant recovery tank.
A CAUTION:
-
Turning the radiator pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
With the coolant recovery tank, you will almost
never have to add coolant
at the radiator. Never
turn the radiator pressure cap
-- even a
little -- when the engine and radiator are hot.
Add coolant mixture at the recovery tank, but be careful
not to spill it.
' ,A CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Don't spill coolant on
a hot engine.
