V6 Engine VS Engine
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) in the United
States, or kPa (kilopascals) in Canada, when the engine
is running. Oil pressure should be
20 to 80 psi (140 to
550 kPa). On the 3800 engine the oil pressure should be
between
20 and 120 psi (140 to 827 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.
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.
I NOTICE:
Damage to your engine from neglected oil
problems can be costly and
is not covered by
your warranty.

When to Add Oil
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,
b-
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.
What Kind of 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
(BPI). Do not use any oil which
does not
carry this Starburst symbol.
If you change your own oil,
c the Starburst symbol on the
you have your oil changed

You should also use the proper viscosity oil for your
vehicle,

5.7L Engine
As shown in the chart, if you have the 5.7L engine,
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 20W-50.

3800 Engine
As shown in the chart, if you have the 3800 engine, 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 (16OC)
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 2OW-50.
