Oil Pressure Gage - Pontiac 1998 Firebird Owner's Manual

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
"Fuel" in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change
the fuel
brand you use. It will require at least one
full tank of the proper fuel to turn
the
light off.
If none of the above steps have made the light turn
off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.

One of these gages may tell you there could be a
problem with
your
engine oil pressure.
The engine oil pressure gage shows the engine
oil
pressure
in psi (pounds per square inch) i n the U n i t e d States, or kpa
(kilopascals) in Canada, when the engine is running. On
the 5.7L V8 engine, oil pressure should be 20 to 80 psi
(140 to 550 P a ) . On the 3800 V6 engine, the oil pressure
should be between 20 and 120 psi (140 to 827 Wa). 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
r e d
area t e l l you that the
engine is low on oil, or that you might have some other oil
problem.

"Engine Oil" in the Index.
