Checking Engine Oil
For diesel engine vehicles, see
Engine Oil in the Duramax Diesel
Supplement.
It is a good idea to check the engine
oil level at each fuel fill. 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 10 6 for 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 this is not
done, 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.
