Choosing the Right Oil Quality
Your vehicle requires the use of a
special oil meeting GM standard
GM4718M.
Your vehicle was filled with
Mobil 1
®
synthetic oil at the
factory, which meets all the
requirements for your vehicle.
Oil meeting this standard will also
have the American Petroleum
Institute Starburst symbol on its
container.
If you change the oil, be sure the
oil you use meets GM Standard
GM 4718M and has the American
Petroleum Institute Starburst
symbol on its container.
Substitute oil not meeting the
GM4718M standard should not be
used for an oil change.
If an oil meeting GM standard
GM4718M is not available, use
an oil that meets the American
Petroleum Institute Service SM
or GM-LL-A-025 service require-
ments.
When you are not changing the oil
but rather adding oil to maintain
the engine oil level, oil meeting
GM Standard GM 4718M may not
be available. In this case, you may
use an SAE 5W-30 oil with the
starburst symbol on its container,
as a substitute at all temperatures.
NOTICE
Failure to use the recommend-
ed oil can result in engine
damage not covered by your
warranty.
