The oil pressure gauge 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.
A reading in the low pressure zone
can be caused by a dangerously
low oil level or some other problem
causing low oil pressure. Check the
oil as soon as possible. See
Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine
oil low can also damage the
engine. The repairs would not be
covered by the vehicle warranty.
Check the oil level as soon as
possible. Add oil if required, but
if the oil level is within the
operating range and the oil
pressure is still low, have the
vehicle serviced. Always follow
the maintenance schedule for
changing engine oil.
If the vehicle has a diesel engine,
see the Duramax diesel supplement
for more information.
