Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
"Fuel" in the .Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation
on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience this condition, change the fuel brand
you use. It will require at least one full tank of the
proper fuel to turn the light
off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.
Oil Pressure Gage
0 \ 80
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 (kilopascals).
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.

Downloaded from www.Manualslib.com manuals search engine When to Add Oil
If the oil is at or below the ADD mark, 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 upper
mark that shows the proper operating range,
your engine could be damaged.
The engine oil filler cap is located on the driver’s side
engine valve cover.
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 (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 low-30 if it’s going
to be
0” F (- 18 O 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.
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.
