If you plan on driving in another country outside the U.S. or Canada,
unleaded fuel may be hard to find. Do not use leaded gasoline. If you use
even one tankful, your emission controls won’t work well or at all. With
continuous use, spark plugs can get fouled, the exhaust system can
corrode, and your engine oil can deteriorate quickly. Your vehicle’s
oxygen sensor will be damaged. All of that means costly repairs that
wouldn’t be covered by your warranty.
To check on fuel availability, ask an auto club, or contact a major oil
company that does business in the country where you’ll be driving.
You can also write us at the following address for advice. Just tell us
where you’re going and give your Vehicle Identification Number (VIN).

FUEL ECOlVOhfY
Your fuel economy (miles per gallon or liters per 100 kilometers) can vary
depending on how your Cadillac is driven. Several vehicles like yours
have been driven through a standard test and their actual fuel economy
was recorded. These readings were adjusted and printed on the fuel
economy window sticker which was attached to your
new Cadillac when it
was delivered and in the Gas Mileage Guide which is available from your
dealership.
c
The fuel economy estimates are based on results of tests required by the
U. S. Environmental Protection Agency (EPA). These tests are used to
certify that vehicles meet the Federal emissions and fuel economy
standards. Cadillac tests prototypes of new vehicles and submits the results
to the EPA. The EPA then confirms the accuracy
of the figures provided by
Cadillac. The vehicles are driven by a professional driver under controlled
-
laboratory conditions, on an instrument similar to a treadmill. These
procedures ensure that each vehicle is tested under identical conditions.
There are
two different fuel economy estimates for each vehicle, one for
city driving and one for highway driving.
To develop these two estimates,
separate tests are used to represent typical everyday city and rural driving.

ENGINE OIL
A “CHECK OIL LEVEL? message will appear when the engine oil is
approximately a quart low.
If the message is displayed, check the dipstick
level and add oil as needed.
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.
L
Turn off the engine and give the oil a few minutes to drain back into the
oil pan.
If you don’t, the oil dipstick might not show the actual level.

the level.
when to Add Oil
If the oil is at or below the ADD line, ADD mark, then you’ll need 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 Specifications”
in the Index.

Don't add too much oil. If your engine has so much oil that the
oil level gets above the.upper mark that shows the proper
operating range, your engine could be damaged.
To remove, turn the oil fill cap counterclockwise.
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.

Beginning midyear 1993, oils of the proper quality for your vehicle will be
identified with this new “starburst” symbol. The “starburst” symbol
indicates that the oil has been certified by the American Petroleum
Institute
(MI), and is suitable for use in your gasoline engine.
You should look for this on the front
of the oil container, and use gnly
oils that display this new symbol.

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 (16OC)
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 1OW-40 or SAE 20W-50.

Downloaded from www.Manualslib.com manuals search engine If you cannot find oils with the new “starburst” symbol on the front of the
container, you should look for and use oils containing the following three
things:
e SHorSG
“SH”or
“SG” must be on the oil container, either by itself or
combined with other quality designations, such as
“SH/CD,”
“SH,SG,CD,” etc. These letters show American Petroleum Institute
(MI) levels of quality.
SAE 1OW-30
e Enerm Conserving I1
Oils with these words on the container
will help you save fuel.
These three things are usually included in a doughnut shaped logo
(symbol) on
most containers. If you cannot find oils with the “starburst”
symbol,
you should look for oils with the doughnut shaped symbol,
containing the three things noted above.
NOTICE:
If you use oils that do not have either the “starburst” symbol or
an
API SH or SG designation, you can cause engine damage not
covered by your warranty.

requirements for your vehicle.

Downloaded from www.Manualslib.com manuals search engine 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
-- 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 (12 000 km) or 12 months
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 Oil Soon” light 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.
How to Reset the Oil Life Indicator
After the oil has been changed, display the “OIL LIFE LEFT” message
by pressing the INFORMATION button. Then press and hold the
RESET button until the display shows “100”. This resets the
oil life index.
The message will remain off until the next oil change
is needed. The
percentage
of oil life remaining may be checked at, any time by pressing
the INFORMATION button several times until the “OIL LIFE LEFT”
message appears. For more information on the Oil Life Index feature,
see
“Oil Life Index” in the Index.
Engine Coolant Heater (Engine Block Heater)
An engine coolant 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 Coolant Heater” in the Index.
