1993 PONTIAC GRAND-AM oil viscosity

Oil Pressure Gage (omrorv)
The oil pressure gage shows the engine
oil pressure in psi (pounds per square
inch) when the engine is running.
Canadian vehicles indicate pressure in
kPa. 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. Have
your vehicle serviced immediately.
A
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.
Charging System Light
The charging system light will come on
briefly when you
turn on the ignition,
but the engine is not running, as a check
to show you it is working. Then it
should go out.
If it stays on when your
engine is running, or comes on while
you are driving, you may have a
problem with the electrical charging
system. It could indicate that
you have a
loose generator drive belt or another
electrical problem. Have it checked
right away. Driving while this light is on
could drain your battery.
If you must drive a short distance with
the light on, be certain to
turn off all
your accessories, such as the radio and
air conditioner.

SAE 5W-30 (2.3L Quad OHC and
Quad 4 Engines)
As shown in the viscosity chart,
SAE 5W-30 is best for your vehicle.
However,
you can use SAE 1OW-30 if
it’s going to be 0°F (-18°C) or above.
These numbers
on an oil container
show its viscosity, or thickness.
Do not use other viscosity oils such as
SAE 1OW-40 or SAE 20W-50.

What Kind of Oil to Use (CONT.)
SAE low-30 (3300 V6 Engine)
As shown in the viscosity chart, SAE
1OW-30 is best for your vehicle.
However, you can use SAE
5W-30 if
it's going
to be colder than 60°F
(16°C) before your next oil change.
When it's very cold, below
0°F
(-18"C), you should use SAE 5W-30.
These numbers on an oil container
show its viscosity, or thickness.
Do not use other viscosity oils such as
SAE 1OW-40 or SAE 2OW-50.

Oils with these words on the container
will help you save fuel.
This doughnut-shaped logo (symbol) is
used on most
oil containers to help you
select the correct oil.
You should look for this on the oil
container, and use only those oils that
display the logo.
