Engine Oil Pressure Gauge
Metric
English
The engine oil pressure gauge shows the engine oil pressure in kPa (kilopascals) or psi (pounds per square inch) when the engine is running.
Oil pressure can vary with engine speed, outside temperature and oil viscosity, but if readings are outside the normal operating range, the oil pressure light comes on. See Engine Oil Pressure Light on page 5‑31 for more information.
A reading outside the normal operating range can be caused by a dangerously low oil level or some other problem causing low oil pressure. Check the vehicle's oil as soon as possible. See “OIL PRESSURE LOW STOP ENGINE” under Engine Oil Messages on page 5‑45 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.
If the vehicle is a hybrid, see the hybrid supplement for more information.
