1998 Oldsmobile Cutlass oil viscosity

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 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

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 (-18°C) or above. These numbers on an oil
container show its viscosity, or thickness.
Do not use
other viscosity oils, such as
SAE 2OW-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.
Engine Oil Additives
Don’t add anything to your oil. Your retailer is ready to
advise
if you think something should be added.
When to Change Engine Oil
If any one of these is true for you, use the short tripkity
maintenance schedule:
0

Most trips are less than 5 to 10 miles (8 to 16 h).
This is particularly important when outside
temperatures are below freezing.
Most
trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer
or use a carrier on top of
your vehicle.
The vehicle
is used for delivery service, police, taxi
or other cornmercial application.
Driving under these conditions causes engine oil to
break down sooner. If any one of these is true for your
vehicle, then you need to change your oil and filter
every 3,000 miles (5
000 km) or 3 months -- whichever
occurs first.
