oil viscosity OLDSMOBILE SILHOUETTE 1995 Owners Manual

Oil Pressure Gage (3800 V6 Engine)
120 '/
40-
If the gage reads in the red warning zone, your engine's
oil level may be dangerously low or there may be
another problem causing low oil pressure.
Driving your vehicle with low
oil pressure can cause
extensive engine damage. Have your vehicle serviced
immediately.
Your oil pressure gage shows the 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. In fact, while the engine is
warming up, the oil pressure will be higher than at the
normal operating temperature. Readings above the red
warning zone indicate the normal operating range.
I
I NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

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 charts:
3.1L V6 Engine
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 OF (- 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.
RECOMMENDED SAE VISCOSITY GRADE ENGINE OILS
FOR BEST FUEL ECONOMY AND COUl STARTING, SELECT THE LOWEST
SAE VISCOSITY GRADE OIL FOR THE EXPECTED TEMPERATURE RANGE.

As shown in the chart, SAE 1OW-30 is best for your
vehicle. However, you can use
SAE 5W-30 if it's going
to be colder than
60 OF ( 16 O C) 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 20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
"Starburst" symbol. Failure to use the proper oil
can result in engine damage not covered by your
warranty.
GM Goodwrench@ oil (in Canada, GM Engine Oil)
meets all the requirements for your vehicle.
