oil viscosity CHEVROLET TRACKER 1995 Owners Manual

What Kind of Oil to Use
Oils of the proper quality for your vehicle can be
identified by looking
for the “Starburst” symbol. The
“Starburst” symbol indicates that the oil has been
certified by the American Petroleum Institute
(API), and
is preferred for use
in your gasoline engine.
If you change your own oil, be sure to 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 5W-30 is best for your
vehicle. However, you can use
SAE 10W-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.
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.
