OIL
PRESS
PSI
The engine oil pressure
gauge shows the engine
oil pressure in psi (pounds
per square inch) or
kPa (kilopascals) when
the engine is running.
Oil pressure should be
20 to 80 psi (140 to 550 Wa).
(In certain situations such as long, extended idles on hot
days, it could read as low as
6 psi (40 kPa) and still be
considered normal.) It may
vary with engine speed,
outside temperature and oil viscosity, but readings above
the shaded area show the normal operating range.
Readings in the shaded area tell you that the engine is
low on oil, or that you might have some other oil
problem. See “Engine Oil”
in the Index.
A CAUTIOh:
Don’t keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.

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.

The engine requires a special oil
meeting GM Standard GM47 18M.
Oils meeting this Standard may be
identified as synthetic, and should
also be identified with the
American Petroleum Institute
Certified For Gasoline Engines
“Starburst” symbol. However, not
all Synthetic API oils with the
“Starburst” symbol will meet this
GM Standard. You should look for
and use only an oil that meets GM
Standard GM47 18M. For the
