Engine Oil
CHECK
OIL
If your vehicle is equipped
with the
3100 engine, you
have a
CHECK OIL light
on the instrument panel.
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. 2.4L Engine
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.
6-12

Checking 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.
I
3100 Engine
The engine oil dipstick handle is yellow. The dipstick
handle for the
2.4L engine is located behind the engine.
The dipstick for the
3100 engine is located in front of
the engine, behind the fan.
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.
6-13

When to Add Oil
If the oil is at or below the ADD line, then you’ll need
to add at least one quart of oil. But you must use the
right kind. This part explains what kind of oil to use. For
crankcase capacity, see “Capacities and Specifications”
in the Index.
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.

What Kind of Oil to Us
3100 Engine
The 2.4L engine oil fill cap is located on the passenger’s
side
of the engine. The 3100 engine oil fill cap is located
in front
of the engine, behind the fan.
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. Oils recommended
for your vehicle can be identified by
looking for the “Starburst” symbol. This symbol
indicates that the oil has been certified by the American
Petroleum Institute (API).
Do not use any oil which
does not carry this Starburst symbol.
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 certified for
gasoline enrzines.

You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:

RECOMMENDED SAE VISCOSITY GRADE ENGINE OILS

DO NOT USE SAE 2OW-50 OR ANY OTHER
GRADE OIL NOT RECOMMENDED
As shown in the chart, SAE 5W-30 is best for your
vehicle. However, you can use
SAE 1OW-30 if it’s going
to be
0°F (- 18 “C) or above. These numbers on an oil
container show its viscosity, or thickness.
Do not use
other viscosity oils, such as
SAE 20W-50.
I NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst” symbol. Failure to
use the
recommended oil can result in engine damage
not covered by your warranty.
GM Goodwrench@ oil meets all the requirements for
your vehicle.
If you are in an area where the temperature falls below
-20°F (-29”C), consider using either an SAE 5W-30
synthetic oil or an
SAE OW-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.

Engine Oil Additives
Don’t add anything to your oil. Your Oldsmobile retailer is
ready to advise if you think something should be added.
When to Change Engine Oil
If any one of these is true for you, use the short trip/city
maintenance schedule:
0
0
0
0
0
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
your vehicle.
The vehicle is used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine oil to
break down sooner. If any
one of these is true for your
vehicle, then you need to change your oil and filter
every
3,000 miles (5 000 km) or 3 months -- whichever
occurs first.
If none of them is true, use the long triphighway
maintenance schedule. Change the oil and filter every
7,500 miles (1 2 500 km) or 12 months -- whichever
occurs first. Driving a vehicle with
a fully warmed
engine under highway conditions causes engine oil to
break down slower.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about the use and disposal
of oil products.)
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from
the filter before disposal. Don’t ever dispose of oil
by putting
it in the trash, pouring it on the ground, into
sewers, or into streams
or bodies of water. Instead,
recycle it by taking it to a place that collects used oil.
If
you have a problem properly disposing of your used oil,
ask your retailer, a service station or a local recycling
center for help.

Air C- :aner
The air cleaner is located on the driver’s side of the
engine compartment.
To check or replace the air filter:
1. Unscrew the four Phillips-head screws, then pull the
cover back.
2. Remove the air cleaner filter.
3. Be sure to install the air cleaner filter and replace the
cover tightly. Refer
to the Maintenance Schedule to determine when to
replace the air filter.
See “Scheduled Maintenance Services” in the Index.
Operating the engine 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.
