This gage tells you if there could be a problem with
your engine oil pressure. The gage shows the engine
oil pressure in psi (pounds per square inch) or
kPa (kilopascals) when the engine is running.
On the 3800 V6 engine, the oil pressure should be
20 to 120 psi (140 to 827 kPa). On the 5.7L V8 engine,
oil pressure should be 20 to 80 psi (140 to 550 kPa).
In certain situations such as long, extended idles on hot
days, it could read as low as 6 psi (40 kPa) and still be
considered normal. It may vary with engine speed,
outside temperature and oil viscosity, but readings
above the red area show the normal operating range.
Readings in the red area tell you that the engine is low
on oil, or that you might have some other oil problem.
See “Engine Oil” in the Index.
CAUTION:
Don’t keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches fire. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered
by your warranty.
