Engine Oil Pressure
Gauge
Metric
English
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
Engine
Oil Messages on page 5 ‑ 41 and
Engine Oil on page 10 ‑ 7 .

WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule for changing engine oil.
If the vehicle has a diesel engine,
see the Duramax diesel supplement
for more information.
