It’s a good idea to check your engine oil every time you get fuel. In order
to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.

to add some oil. But you must use the right kind. This section explains
what kind
of oil to use. For crankcase capacity, see “Capacities and

What Kind of Oil to Use:
Look for three things:
SG
“SG” must be on the oil container, either by itself or combined with
other quality designations, such as
“SG/CC,,” “SG/CD,” ggs~s~,~c,9’
etc. These letters show American Petroleum Institute (MI) levels of
quality.

FOR BEST FUEL ECONOMY AND COLD STARTING, SELECT THE LOWEST
SAE VISCOSITY GRADE OIL FOR THE EXPECTED TEMPERATURE RANGE.
HOT
WEAntER
SAE 1OW-30
As shown in the viscosity 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
(16 C) before your next oil change. When it's very cold, below 0 * F
(-18OC), 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 1OW-40 or SAE 2OW-50.
0 Energy Conserving I1
Oils with these words on the container will help you save fuel.

Downloaded from www.Manualslib.com manuals search engine This doughnut-shaped logo (symbol) is used on most oil containers to
help you select the correct oil.
You should look for this on the oil container, and use
only those oils that
display the logo.
GM Goodwrench@ oil
(in Canada, GM Engine Oil) meets all the
requirements for your vehicle.
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 vehicle is equipped with an engine oil
life index (EOLI) feature as part of the Driver Information Center
display (DIC). Oil change intervals are determined
by the EOLI and will
usually fall at, or between, the two recommended alternative intervals of
3,000 miles (5,000 kilometers) and 7,500 miles (12,500 kilometers), but
could
be shorter than 3,000 miles (5,000 kilometers) under some very
severe driving conditions shown in Schedule I. The system will also
indicate the need for an
oil change if 7,500 miles (12,500 kilometers) or
one year has passed.
Engine oil life remaining
is displayed through engine data as the ‘OIL
LIFE INDEX’ and as a
‘CHANGE ENGINE OIL message. The ‘OIL
LIFE INDEX’ display includes a number between
0 and 100. This is the
percentage
of oil life REMAINING based on driving conditions and
mileage driven since the last time
of the oil life indicator was reset. When
the remaining oil life is less than
lo%, a ‘CHANGE OIL SOON’ message
will appear. This is a reminder to schedule an engine oil change. When
the oil life index reaches
0, the ‘CHANGE ENGINE OIL: message will
appear. This indicates that no oil life remains and the oil should be
changed as soon as possible, but certainly within the next 200 miles (320
km).
The EOLI will not detect excessively dusty conditions or engine
malfunctions which may effect the oil.
If you drive in dusty areas, change
the engine
oil after every 3,000 miles (5,000 kilometers) or 3 months
(whichever comes first), unless instructed
to do so sooner by the DIC.
On Northstar 4.6 Liter engine equipped vehicles a ‘CHECK OIL LEVEE
message will appear whenever the oil level’s approximately one quart low.

Downloaded from www.Manualslib.com manuals search engine How To Reset the Oil Life Indicator: After the oil has been changed,
display the ‘OIL LIFE INDEX’ message by pressing the
‘INFORMATION’ button. Then press and hold the
‘STORE/RECALL
button until the display shows ‘100’. This will reset the oil life index. The
message will remain
OFF until the next oil change is needed. The
percentage
of oil life remaining may be check at any item by pressing the
INFORMATION button several times until the ‘OIL LIFE INDEX
message appears.
Engine Block Heater: An engine block heater can be a big help if you
have to park outside in very cold weather, -20” F (-29 “C) or colder. If
your vehicle
has this option, see “Engine Block Heater” in the Index.
What to Do with Used Oil:
A CAUTION
Used engine oil contains things that have caused skin cancer in
laboratory animals. Don’t let used oil stay on your skin for very
long. Clean your skin and nails with soap and water, or a good
hand cleaner. Wash or properlv throw away clothing or rags
containing used engine
oil.
Used oil can be a real threat to the environment. If you change your own
oil, be sure to drain all free-flowing oil from the filter before disposal.
Don’t ever dispose
of oil by pouring it on the ground, into sewers, or into
streams or bodies
of water. Instead, recycle it by taking it to a place that
collects used oil.
If you have a problem properly disposing of your used
oil, ask your dealer, a service station or a local recycling center for help.
