Downloaded from www.Manualslib.com manuals search engine Engine Oil Pressure Gage
The engine oil pressure
gage 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. The
engine oil pressure can also be displayed using the
GAGES button on the Driver Information Center (DIC).
See “Driver Information Center” in the Index.
A CAUTION:
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
2OW-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.

USAGE
Engine Oil
FLUIDLUBRICANT
The engine requires a special
Engine Oil meeting GM Standard
GM4718M. 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
proper viscosity, see “Engine Oil”
in the Index.
