Downloaded from www.Manualslib.com manuals search engine What Kind of 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 InstitGte certified
for gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:

Downloaded from www.Manualslib.com manuals search engine 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
recommended oil can result in engine damage not
covered by your warranty.
I I
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 Cadillac dealer is
ready to advise if
you think something should be added.
When to Change Engine Oil
Your Cadillac has an Oil Life Indicator. 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 if the
CHANGE
ENGINE OIL message comes on.
Remember to reset the Oil Life Indicator when the
oil has been changed. For more information, see
“Oil Life Indicator” in the Index.
