oil viscosity OLDSMOBILE BRAVADA 1997 Owners Manual

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 one or more of these conditions,
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 retailer or qualified service center check the
vehicle. Your retailer has
the proper test equipment and
diagnostic tools to fix any mechanical
or electrical
problems that may have developed.
Engine Oil Pressure Gage
OIL 0-
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.

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.
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 recom~nended 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. SAE SW-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 LIS(;:
other viscosity oils, such as SAE 20W-SO.
I NOTICE:
Use only engine oil with the American Petroleum
Institute Certif'ied 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 a11 area where the temperature fills below
-20°F (-29°C). consider using either an SAE SW-30
synthetic oil or an SAE OW-30 oil. Both will provide
easier cold starting and better protection for engine
at extremely
low temperatures.
