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 0335.
.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
Overview0331 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.
Follow these guidelines:
.To get an accurate reading,
park the vehicle on level
ground. Check the engine oil
level after the engine has

Selecting the Right
Engine Oil
Selecting the right engine oil
depends on both the proper
oil specification and viscosity
grade. See Recommended
Fluids and Lubricants0429.
Specification
Use full synthetic 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.
Caution
Failure to use the
recommended engine oil or
equivalent can result in
engine damage not covered
by the vehicle warranty.
Viscosity Grade
Use SAE 0W-20 viscosity
grade engine oil.
When selecting an oil of the
appropriate viscosity grade, it
is recommended to select an
oil of the correct specification.
See “Specification” earlier in
this section.
Engine Oil Additives/
Engine Oil Flushes
Do not add anything to the oil.
The recommended oils
meeting the dexos1
specification are all that is
needed for good performance
and engine protection. Engine oil system flushes are
not recommended and could
cause engine damage not
covered by the vehicle
warranty.
What to Do with Used Oil
Used engine oil contains
certain elements that can be
unhealthy for your skin and
could even cause cancer. Do
not let used oil stay on your
skin for very long. Clean your
skin and nails with soap and
water, or a good hand cleaner.
Wash or properly dispose of
clothing or rags containing
used engine oil. See the
manufacturer's warnings
about the use and disposal of
oil products.
Used oil can be a threat to the
environment. If you change
your own oil, be sure to drain
all the oil from the filter before
disposal. Never dispose of oil
by putting it in the trash or
pouring it on the ground, into
sewers, or into streams or
