Engine Oil
If the LOW OIL LEVEL
light appears on the
instrument cluster, it
means you need to
check your engine oil
level right away.

Checking 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.
You should check your engine oil level regularly;
this is an added reminder.

The engine oil dipstick handle is the yellow loop located
near the front of the engine. See Engine Comparfment

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 bottom hatchmark, 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 engine oil crankcase capacity, see Capacities
and Specifications on page 5- 102.
Nofice: 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 will have one of these symbols on
it, depending on the engine. It is located on the front
of the engine, near the center of the engine
compartment and the yellow-looped engine oil dipstick.
See Engine Compartment Overview on page
5-12
for more information on location.
Be sure to
fill it enough to put the level somewhere
in the proper operating range in the cross-hatched area.
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 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 choose to perform
the engine oil change
service yourself, be sure
the oil you use 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 viscosity chart.

DO NOT USE SAE 1OW-40, SAE 2OW-50 OR ANY OTHER VlSCOSlN GRADE OIL NOT RECOMMENDED
As in the chart shown previously, if you have the
3100 V6 engine, SAE 5W-30 is the only viscosity grade
recommended for your vehicle. You should look for
and use only oils which have the API Starburst symbol
and which are also identified as
SA€ 5W-30. If you
cannot find such SAE 5W-30 oils, you can use an
SAE IOW-30 oil which has the API Starburst symbol,
if it’s going to be 0°F (-18°C) or above. Do not use
other viscosity grade oils, such as SAE IOW-40
or SAE 20W-50 under any conditions.
As shown in the following chart,
if you have the
3800 V6 engine, SAE IOW-30 is the viscosity grade
recommended for your vehicle. However, you can use
SAE 5W-30 if it’s going to be colder than 60°F (16°C)
before your next
oil change. When it is very cold, colder
than 0°F
(-1 8°C) you should use an SAE 5W-30 oil.
These numbers on an oil container show its viscosity,
or thickness.
Do not use other viscosity grade oils,
such as SAE 1
OW-40 or SAE 20W-50 under any
conditions.
