Cadillac 2006 XLR - Manual (Page 171)

Engine Oil Pressure Gage
The engine oil pressure gage shows the engine oil
pressure in psi (pounds per square inch) or kPa
(kilopascals) when the engine is running.
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.
The Driver Information Center (DIC) may display
messages regarding the oil condition. See DIC Warnings
and Messages on page 3-67 and Engine Oil on
page 6-13.
{ CAUTION:
Do not 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: Lack of proper engine oil maintenance
may damage the engine. The repairs would not be
covered by your warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.
