1996 CHEVROLET EXPRESS oil viscosity

Downloaded from www.Manualslib.com manuals search engine Oil Pressure Gage
The oil pressure gage
pressure
in psi (pounds
shows
the engine oil
per square inch) when the
engine is running. Canadian
vehicles indicate pressure
in kPa (kilopascals).
OIL 93
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a
dangerously low
oil level or other problem causing low
oil pressure. Check your oil as soon as possible.
A C -1TION:
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.

The engine oil filler cap is located between the air
cleaner and engine oil dipstick.
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. 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:

DO NOT USE SAE 2OW-50 OR ANY OTHER GRADE OIL NOT RECOMMENDED
As shown in the chart, SAE 5W-30 is best for your
vehicle. However, you can use
SAE IOW-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.
I 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.
Engine Oil Additives
Don’t add anything to your oil. Your GM dealer is ready
to advise if you think something should be added.
