Engine Oil

For diesel engine vehicles, see
Engine Oil in the Duramax Diesel
Supplement.
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:
Always 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 on page 10 14.
Always dispose of engine oil
properly. See What to Do With
Used Oil in this section.
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground. The
engine oil dipstick handle is a yellow
loop. See Engine Compartment
Overview on page 10 8 for the
location of the engine oil dipstick.

Obtaining an accurate oil level
reading is essential:
1. If the engine has been running
recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking the oil level too soon
after engine shut off will not
provide an accurate oil level
reading.
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.
