Owner's Manual

SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is best
for your vehicle. However, you can use
SAE
1OW-30 if it’s going to be 0°F (-18°C) or above.
These numbers
on an oil container show its viscosity,
or thickness. Do not use other viscosity oils such as
SAE 20W-50.
Oils meeting these
requirements should also
have the “Starburst”
symbol on the container.
This symbol indicates that
the oil has been certified
by the American Petroleum
Institute (API).
Do not use
any oil which does not
carry this Starburst symbol.
You should look for this on the oil container, and use
only those oils that are identified as meeting GM
Standard GM4718M and have the Starburst symbol on
the front of the oil container.
Your Corvette engine is filled at the factory with a
Mobil 1
@ synthetic oil, which meets all requirements
for your vehicle.
Substitute Oil: When adding oil to maintain engine
oil level, oil meeting GM Standard GM47 18M may
not be available. You can add substitute oil designated
SAE 5W-30 with the “Starburst” symbol at all
temperatures.
If temperatures are above 0” F (- 18 ” C),
you may substitute SAE 1OW-30 with the “Starburst”
symbol. Substitute oil not meeting GM Standard
GM47 18M should not be used for an oil change.
Engine Oil Additives
Don’t add anything to your oil. Your Corvette dealer is
ready to advise
if you think something should be added.
