When to Add Oil: If the oil is at or below the ADD line, then you’ll need to -
add some oil. But you must use the right kind. This section explains what I
kind of oil to use. For crankcase capacity, see “Capacities and
Specifications”
in the Index.
Just
fill it enough to put the level somewhere in the proper operating
range. Push the dipstick all the way back in when you’re through.

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,” “SF,SG,CC,”
etc. These letters show American Petroleum Institute (MI) levels of
quality.

Oils with these words on the container will help you save fuel.
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 indicator (EOLI) feature. 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).
When the oil life index reaches
0, the “CHANGE OII? light come on.
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
“CHANGE
OW light.

Downloaded from www.Manualslib.com manuals search engine Engine Block Heater Option: An engine block heater can be a big help if
you have to park outside in
very cold weather, 0°F (-18OC) or colder. If
your vehicle has this option, see “Engine Block Heater”
in the Index.
How
To Reset the Oil Life Indicator: After the oil has been changed,
you’ll need to reset your system.
To do that, turn the ignition switch to the
“ON” position with the engine stopped fully depress and release the
accelerator pedal
3 times within 5 seconds.
If the “CHANGE OIC‘ light comes on and stays on for 5 seconds, it did
not reset. You’ll need to reset the system again.
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 properly 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.

much can mean that some of the fluid could come out and fall
on hot engine parts, starting
a fire. Be sure to get an accurate
reading if you check
your transmission fluid. I

Wait at least 30 minutes before checking the transmission fluid level if
you have been driving:
0 When outside temperatures are above 90” F (32” C).
n !‘ b
0 At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
0 While pulling a trailer.
To get the right reading, the fluid should be at normal operating
temperature, which is
180°F to 200°F (82°C to 93OC).
To check transmission fluid hot: Get the vehicle warmed up by driving
about
15 miles (24 km) when outside temperatures are above 50°F
(10°C). If it’s colder than 50°F (lO°C), drive the vehicle in “D” (3rd
Gear) until the engine temperature gage moves and then remains steady
-
for ten minutes. Then follow the hot check procedures. t3
