Downloaded from www.Manualslib.com manuals search engine 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.
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.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and
is not covered by
your warranty.
Low Oil Light
This warning light should
come on while you are
starting your engine.
If
the light doesn’t come on,
have
it repaired.
LOW OIL
I
If the light stays on after starting your engine, your
engine oil level may be too low. You may need to add
oil. See “Engine Oil’’ in the Index.
NOTICE:
The oil level monitoring system only checks the
oil level when you are starting your engine. It
does not keep monitoring the level once the
engine is running. Also, the oil level check only
works when the engine has been turned
off long
enough for the
oil to drain back into the oil pan.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the
cross-hatched area upper mark that shows the proper operating range, your engine
could be damaged.
The oil fill cap is located on the valve cover near the
oil dipstick.
Be sure to 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.
What Kind of Engine Oil to Use
Oils recommended for your vehicle can be identified by
looking
for the “Starburst” symbol. This symbol
indicates that the oil has been certified by the American
Petroleum Institute (API).
Do not use any oil which
does not carry this Starburst symbol.
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
into 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:

As shown in the chart, if you have the 3800 engine, SAE
low-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, 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 20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified
For Gasoline Engines
"Starburst" symbol. Failure
to use the
recommended oil can result in engine damage not
covered by your warranty.
GM Goodwrench' oil meets all the requirements for
your vehicle.
If you are in an area where the temperature falls below
-20°F (-29"C), consider using either
an SAE 5W-30
synthetic oil or an
SAE OW-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
