Check Oil Light
80
Your engine is
equipped with
an oil
level monitoring
system. When the
ignition key is turned
on, the CHECK
OIL
light will briefly flash.
If the light stays on, stop the vehicle on a level surface
and turn the engine
off. Check the oil level using the
engine oil dipstick. (See “Engine Oil” in the Index.)
If
the light does not flash, have the low oil level sensor
system repaired
so it will be ready to warn you if there’s
a problem.
I NOTICE:
The oil level monitoring system only checks oil
level during the brief period between key on and
engine crank.
It does not monitor engine oil level
when the engine is running. Additionally, an oil
level check is only performed if the engine has
been turned
off for a considerable period of time
allowing the oil normally in circulation to drain
back into the oil pan.

Underhood Light
Your parking lights or headlights must be on for the
underhood light
to function when you open the hood.
Engine Oil
If the CHECK OIL light on the instrument panel comes
on, it means you need to check your engine oil level
right away. For more information, see
”CHECK OIL
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 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.
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.
To Check Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
Checking Engine Oil
The engine oil dipstick handle is yellow. The dipstick
handle for the
2.3L L-4 is located behind the engine.
The dipstick for the 3.1L
V-6 is located in front of the
engine behind the fan.

When to Add Oil
If the oil is at or below the ADD line, then you’ll need to
add some oil. But you must use the right kind. This put
explains what kind
of oil to use. For crankcase capacity,
see “Capacities and Specifications”
in the Index.
I NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.
Just fill it enough to put the level somewhere in the
proper operating range. Push the dipstick all the way
back in when you’re through.
What Kind of Oil to Use
Oils of the proper quality for your vehicle can be
identified
by looking for the “Starburst” symbol. The
“Starburst” symbol indicates that the
oil has been
certified by the American Petroleum Institute
(API), and
is preferred for use
in your gasoline engine.
If you change your own oil, be sure you use oil that has
the “Starburst” symbol
on the front of the oil container.
If you have your oil changed for you, be sure the oil put
into your engine is American Petroleum Institute
certificd
for gasoline engines.
You should also use the proper viscosity oil
for your
vehicle,
as shown in the following chart:

Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level
is when the engine oil is changed. Refer to the
Maintenance Schedule to determine when to change
your fluid. See “Scheduled Maintenance Services’’ in the
Index.
How to Check
Because this operation can be a little difficult, you may
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
transaxle.
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 to get an accurate reading if you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level if you have been driving:
0 When outside temperatures are above 90 OF (32 O C).
At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
While pulling a trailer.

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid
to use. See “Recommended
Fluids and Lubricants” in the Index.
If the fluid level
is low, add only enough of the proper
fluid to bring the level into the cross-hatched area on
the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the
dipstick hole to bring it
to the proper 1evel.It doesn’t
take much fluid, generally less than a pint
(0.5L).
Don’t overfill. We recommend you use only fluid
labeled DEXRON@-111, because fluid with that label
is made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON@-I11
is not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under “How to Check.”
When the correct fluid level is obtained, push the
dipstick back in all the way.
Manual Transaxle Fluid
When to Check
A good time to have it checked is when the engine oil is
changed. However, the fluid in your manual transaxle
doesn’t require changing.
How to Check
Because this operation can be a little difficult, you may
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
transaxle.
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 to
get an accurate reading if you check your
transaxle fluid.
