oil than it would with normal use. Low oil levels can
damage the engine. Be sure to check the oil level
often during racing or other competitive driving and
keep the level at or near the upper mark that
shows the proper operating range on the engine oil
dipstick. For information on how to add oil, see

Engine Oil
If the oil pressure light
and/or the Oil Pressure
Low - Stop Engine
message on the DIC
appears on the instrument
cluster, it means you
need to check your engine
oil level right away.
For more information, see “Oil Pressure Low - Stop
Engine” underDIC Warnings and Messages on
page 3-65andOil Pressure Light on page 3-48.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is 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 a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. 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.

If the oil is at or below the cross-hatched area at the
tip of the dipstick, then you will need to add at least
one quart of oil. But you must use the right kind. This
section explains what kind of oil to use. For engine
oil crankcase capacity, seeCapacities and
Specications on page 5-107.
Notice:Do not add too much oil. If the engine
has so much oil that the oil level gets above the
cross-hatched area that shows the proper operating
range, the engine could be damaged.SeeEngine Compartment Overview on page 5-12for
the location of the engine oil ll cap.
Be sure to add enough oil to put the level somewhere
in the proper operating range. Push the dipstick all
the way back in when you are through. 5.7L V8 Engine
