Engine Oil

To ensure proper engine performance
and long life, careful attention must
be paid to engine oil. Following these
simple, but important steps will help
protect your investment:
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
Selecting the Right Engine Oil in
this section.
Check the engine oil level regularly
and maintain the proper oil level.
See Checking Engine Oil and
When to Add Engine Oil in this
section.
Change the engine oil at the
appropriate time. See Engine Oil
Life System 0 239.
Always dispose of engine oil
properly. See What to Do with
Used Oil in this section.
Checking Engine Oil
Check the engine oil level regularly,
every 650 km (400 mi), especially prior
to a long trip. The engine oil dipstick
handle is a loop. See Engine
Compartment Overview 0 233 for the
location.
Warning
The engine oil dipstick handle may
be hot; it could burn you. Use a
towel or glove to touch the dipstick
handle.
If a low oil Driver Information Center
(DIC) message displays, check the oil
level.
VEHICLE CARE
Follow these guidelines:
To get an accurate reading, park
the vehicle on level ground. Check
the engine oil level after the
engine has been off for at least
two hours. Checking the engine oil
level on steep grades or too soon
after engine shutoff can result in
incorrect readings. Accuracy
improves when checking a cold
engine prior to starting. Remove
the dipstick and check the level.
If unable to wait two hours, the
engine must be off for at least
15 minutes if the engine is warm,
or at least 30 minutes if the
engine is not warm. Pull out the
dipstick, wipe it with a clean paper
towel or cloth, then push it back
in all the way. Remove it again,
keeping the tip down, and check
the level.
