1998 BUICK REGAL 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.
I RECOMMENDED SAE VISCOSITY GRADE ENGINE OILS
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 1OW-30 is best for your
vehicle. However, you can
use SAE 5W-30 if it’s going
to be colder than
60°F (1 6 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
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 dealer is ready to
advise if you think something should be added.
When to Change Engine Oil
Your vehicle has an Oil Life Monitor. This feature
will let you know when to change your oil and
filter
-- usually between 3,000 miles (5 000 km) and
7,500 miles (12 500 km) since your last oil change.
Under severe conditions, the indicator may come on
before
3,000 miles (5 000 km). Never drive your vehicle
more than
7,500 miles (12 500 km) or 12 months
(whichever occurs first) without an oil change.
The system won’t detect dust
in the oil. So, if you
drive in a dusty area, be sure to change your oil every
3,000 miles (5 000 km) or sooner. Remember to reset
the CHANGE OIL
SOON light when the oil has been
changed. For more information, see “Change Oil Soon
Light” in the Index.
How to Reset the CHANGE OIL SOON Light
After changing the engine oil, the system must be reset.
With the ignition key in RUN but the engine off, fully
push and release the accelerator pedal slowly three times
within five seconds. If
the CHANGE OIL SOON light
flashes, the system is resetting.
Turn the key to OFF,
