Engine Oil
If the LOW OIL light on
the instrument panel comes
on, it means you need to
check your engine oil
level right away.
For more information, see ªLow Oil Level Lightº 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.

The engine oil dipstick handle is the yellow loop near
the front of the engine.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don't, the oil dipstick
might not show the actual level.

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.

When to Add Engine Oil
If the oil is at or below the lower mark, 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 ªCapacities and Specificationsº
in the Index.
NOTICE:
Don't add too much oil. If your engine has so
much oil that the oil level gets above the
cross
-hatched area that shows the proper
operating range, your engine could be damaged.
The engine oil fill cap is located toward the front of the
engine near the yellow
-looped engine oil dipstick.

Be sure to 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 Engine Oil to Use
Oils recommended for your vehicle can be identified by
looking for the ªStarburstº 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 engines.
You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:

6-17
As shown in the chart, if you have the 3100 V6 engine,
SAE 5W
-30 is best for your vehicle. However, you can
use SAE 10W
-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.
