1996 PONTIAC BONNEVILLE oil viscosity

Even if you have a low oil level, the light will go off for
15 to 20 seconds. Then, if the oil level is low, and it has
been at least eight minutes
since your engine was last
running, the
CHECK OIL LEVEL light will come on
for
20 to 40 seconds. The eight-minute delay allows the
majority of the oil to drain back into the oil pan and
prevent a false low condition.
If the CHECK OIL LEVEL warning comes on, the oil
level should be checked at the oil dipstick. If the level is
low, the engine
oil should be brought up to the proper
level. See “Engine Oil” in the Index. After restoring the\

proper level and waiting for the eight-minute drainback,
the key can be turned to the
RUN position and the
CHECK OIL LEVEL warning light should only come
on as a bulb check.
Oil Pressure Gage
The oil pressure gage shows
the engine
oil pressure in psi
(pounds per square inch)
when
the engine is rwmhg.
Canadian vehicles indicate
pressure in kPa (kiloPascals).
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the red
warning zone indicate the normal operating range.
A reading in the red zone may be caused by a,’
dangerously low
oil level or other problem causing low
oil pressure.
The CHECK GAGES light will go on and. a
warning ch@e
will sound, if you have this option.
Driving your
vehicle with low oil pressure can cause
extensive ,engine, damage.
