oil viscosity OLDSMOBILE BRAVADA 1998 Owners Manual

Engine Oil Pressure Gage
The oil pressure gage shows
the engine
oil pressure in
psi (pounds per square inch)
when the engine
is running.
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 problems causing low
oil pressure.
I
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.
1 NOTICE:
Damage to your engine from neglected oil
problems can
be costly and is not covered by
your warranty.

When to Add Engine Oil
If the oil is at or below the ADD line, then you’ll need
to add at least one quart of 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.
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
A
FOR rn L 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

SAE CW-30 PREFERRED
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 1OW-30 if it's going
to be 0°F (- 1 8°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.
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.
