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 10-9.
.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 loop.
SeeEngine Compartment Overview
on page 10-6 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 shutoff will not
provide an accurate oil level
reading.

10-8 Vehicle Care
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
2. Pull out the dipstick and 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.
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.
{Caution
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
area that shows the proper
operating range, the engine could
be damaged. You should drain
out the excess oil or limit driving
of the vehicle and seek a service
professional to remove the
excess amount of oil.
See Engine Compartment Overview
on page 10-6 for the location of the
engine oil fill cap. Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back in when through.
Selecting the Right Engine Oil
Selecting the right engine oil
depends on both the proper oil
specification and viscosity grade.
See
Recommended Fluids and
Lubricants on page 11-10.
Specification
Ask for and use engine oils that
meet the dexos1™ specification.
Engine oils that have been
approved by GM as meeting the
dexos1 specification are marked
with the dexos1 approved logo. See
www.gmdexos.com.

10-12 Vehicle Care
Because the vehicle is equipped
with a high-efficiency air-to-oil
cooler, the transmission fluid
temperature may not reach the
required hot fluid level checking
temperature under normal lightly
loaded driving vehicle conditions.
Checking the Fluid Level
Prepare the vehicle:
1. Park the vehicle on a levelplace. Keep the engine running.
2. With the parking brake applied, place the shift lever in P (Park).
3. With a foot on the brake pedal, move the shift lever through
each gear range, pausing for
about three seconds in each
range. When M is reached,
move the selector from M1
through M3. Then, position the
shift lever in P (Park).
4. Let the engine run at idle for two minutes or more.
Then, without shutting off the
engine, use the steps that follow.
The transmission dipstick is near
the center of the engine
compartment and will be labeled
with the graphic shown.
See Engine Compartment Overview
on page 10-6 for more information
on location.
1. COLD Range
2. WARM Range
3. HOT Range
1. Flip the handle up, pull out the dipstick, and wipe it with a clean
rag or paper towel. 2. Push it back in all the way, wait
three seconds, and pull it back
out again.
3. Check both sides of the dipstick, and read the lower level. The
fluid level must be in the
COLD (1) range for a cold
check, transmission temperature
27 °C to 32 °C (80 °F to 90 °F);
between the COLD (1) and
HOT (3) range for a WARM (2)
check, 50 °C to 60 °C (122 °F to
140 °F); or in the HOT (3)
cross-hatched range for a hot
check, 71 °C to 93 °C (160 °F to
200 °F). Be sure to keep the
dipstick pointed down to get an
accurate reading.
4. If the fluid level is in the acceptable range, push the
dipstick back in all the way; then
flip the handle down to lock the
dipstick in place.
