Oil Pressure Gage
Readings above the shaded warning zone indicate the
normal operating range. Oil pressure may vary with
engine speed, outside temperature and oil viscosity.
A reading in the shaded warning zone may be caused
by a low oil level or another problem causing low oil
pressure. On vehicles with the systems monitor,
the CHECK GAGES light will come on and a warning
chime will sound.On vehicles with a DIC, a CHECK GAGES OIL
PRESSURE message will be displayed and a warning
chime will sound. SeeDIC Warnings and Messages
on page 3-61for more information.
{CAUTION:
Do not keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be
covered by your warranty. Always follow the
maintenance schedule in this manual for changing

SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is best
for your vehicle. However, if it is going to be
0°F (–18°C) or above and SAE 5W-30 is not
available, you may use SAE 10W-30.
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
certi ed by the American
Petroleum Institute (API).
You should look for this information on the oil container,
and useonlythose oils that are identi ed as meeting
GM Standard GM6094M and have the starburst symbol
on the front of the oil container.
