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 ‑ 13 .
. 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.
When to Add Engine Oil
If the oil is below the cross-hatched
area at the tip of the dipstick, add
1 L (1 qt) of the recommended oil
and then recheck the level. See
“ Selecting the Right Engine Oil ” in
this section for an explanation of
what kind of oil to use. For engine
oil crankcase capacity, see
Capacities and Specifications on
page 12
‑ 2 .
Notice: Do not add too much oil.
Oil levels above or below the
acceptable operating range
shown on the dipstick are harmful
to the engine. If you find that you
have an oil level above the
operating range, i.e. the engine
has so much oil that the oil level
gets above the cross-hatched
