Maintenance Schedule; Oil Pressure Gage - GMC 2008 Sierra 1500 Pickup Owner's Manual

Oil Pressure Gage

United States
The oil pressure gage shows the engine oil pressure
in psi (pounds per square inch) when the engine
is running. Canadian vehicles indicate pressure in
kPa (kilopascals).
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
3-48
A reading in the low pressure zone may be caused
by a dangerously low oil level or some other problem
causing low oil pressure. Check your oil as soon
as possible. See DIC Warnings and Messages on
page 3-59 and Engine Oil on page 5-13.

Do not keep driving if the oil pressure is low.

it catches fire. You or others could be burned.

your vehicle serviced.
