oil viscosity PONTIAC FIREBIRD 1995 Owners Manual

Enghe Oil Pressure Gauge
3.8L Engine Only
This gage tells you if there could be a problem with your
engine oil pressure.
The engine oil pressure gauge shows the engine oil
pressure in psi (pounds per square inch) in the
U.S., or
kPa (kilopascals) in Canada, when the engine is running.
Oil pressure should be
20 to 80 psi (140 to 550 kPa). 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.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by your
warranty.

When to Add Oil What Kind of Oil to Use
If the oil is at or below the ADD line, then you’ll need to
add some
oil. But you must use the right kind. This part
explains what kind.of oil to use. For crankcase capacity,
see ‘‘Capacities and Specifications” in the Index.
NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the
cross-hatched area that shows the proper
operating range, your engine could be damaged.
Oils of the proper quality for your vehicle can be
identified by looking for the “Starburst” symbol. The
“Starburst” symbol indicates that the
oil has been
certified by the American Petroleum Institute (API), and
is preferred
for use in your gasoline engine.
Just fill it enough to put the level somewhere in the
proper operating range. Push the dipstick all the way
back in when you’re through.
If you change your own oil, be sure you use oil that has
the “Starburst” symbol on the front of the oil container.
If you have your oil changed
for you, be sure the oil put
ihto your engine is American Petroleum Institute
certified for gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:

change. When it’s very cold, you should use
SAE

such as
SAE 20W-50.

NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines “Starburst” symbol. Failure to use the proper oil
can result in engine damage not covered by your
warranty.
GM Goodwrench@ oil (in Canada, GM Engine Oil)
meets all the requirements for your vehicle.
