What about gasoline with blending materials that contain oxygen
(oxygenates), such as
MTBE or alcohol?
MTBE is “methyl tertiary-butyl ether.” Fuel that is no more than
15%
MTBE is fine for your vehicle.
Ethanol is ethyl or grain alcohol. Properly-blended fuel that is no more
than
10% ethanol is fine for your vehicle.
Methanol is methyl or wood alcohol.
NOTICE:
Fuel that is more than 5% methanol is bad for your vehicle.
Don’t use it. It can corrode metal parts in your
fuel system and
also damage plastic and rubber parts. That damage wouldn’t be
covered under your warranty.
And even at 5% or less, there must
be %osolvents” and corrosion preventers
in this fuel to help
avoid these problems.
Gasolines for Cleaner Air
Your use of gasoline with deposit control additives will help prevent
deposits from forming in your engine and fuel system. That helps keep
your engine in tune and your emission control system working properly.
It’s good for your vehicle, and you’ll be doing your part for cleaner air.
Many gasolines are now blended with oxygenates. General Motors
recommends that you use gasolines with these blending materials, such as
MTBE and ethanol. By doing so, you can help clean the air, especially in
those parts of the country that have high carbon monoxide levels.
- In addition, some gasoline suppliers are now producing reformulated
gasolines. These gasolines are specially desighed to reduce vehicle
emissions. General Motors recommends that
you use reformulated
F gasoline. By doing so, you can help clean the air, especially in those parts
i of the country that have high ozone levels.
F?
You should ask your service station operators if their gasolines contain
deposit control additives and oxygenates, and if they have been
reformulated to reduce vehicle emissions.

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 Numbe\

FUEL ECONOMY
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 econ\
omy
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.
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.
The test used to determine the city fuel economy estimate simulates a
7.5 mile (12 km), stop and go trip with. an average speed of 20 mph
(32 km/h). The trip takes 23, minutes and: has 18 stops. About one fifth
of the time is spent idling, as in waiting at traffic lights or in rush hour
traffic.
Two. kinds of engine starts are used: a cold start, which is similar to
starting a car in the morning after it has been parked all night and a hot
start, which is similar to restarting a vehicle after it has been warmed up,
driven and stopped for a short time.

The test used to determine the highway fuel economy estimate represents
a mixture of “non-city” driving. Segments corresponding to different
kinds of rural roads and interstate highways are included. The test
simulates a
10- mile (17 km) trip with an average speed. of 48 mph (77
km/h). The test is run from a hot start and has little idling time and no
stops.
To assure that the fuel economy numbers are most useful for consumers,
the EPA adjusts. these .laboratory test. results. to account for the difference
between controlled laboratory conditions and actual, driving on the road.
The laboratory fuel economy results are adjusted downward
to arrive at
the estimates on the fuel economy window sticker and the
Gas Mileage
Guide. The city estimate is lowered by
10 percent and the highway
estimate is lowered by
22 percent from the laboratory test results.
Experience has proven that these adjustments make the mile:age
estimates-correspond more closely to the actual fuel economy realized
by
the average driver.

Downloaded from www.Manualslib.com manuals search engine Even though these figures are adjusted, they still represent what the
average driver
will get. Your fuel economy may be significantly higher or
lower, depending
on how, when, and where your vehicle is driven. Here
are some things you can do to increase fuel economy;
Combine errands into one trip.
Turn the engine off rather than letting it idle for more than a minute.
Have your Cadillac serviced as described in the maintenance booklet.
Keep tires inflated to recommended pressures.
Anticipate traffic stops.
Here are some things that
will lower fuel economy:
Quick acceleration.
Traveling at higher speeds. Traveling at 65 mph instead of 55 mph
0 Carrying unnecessary weight in the vehicle.
Rewing the engine. This is not necessary for your vehicle.
lowers fuel economy
by 15 percent.
Operating your vehicle with the suspension out of alignment or with
the wheels and tires out of balance.
Use of electrical accessories which require high amperage when they
are not needed.
Even things beyond your control such as weather conditions affe\
ct your
fuel economy. Driving up steep hills, in rain or snow, and into a strong
wind will lower fuel economy. In the lower
left corner of the fuel
economy window sticker from your vehicle is the range
of city and
highway
fuel economy you can expect to get from your Cadillac. If you
are doing everything to raise your fuel economy, but are still not within
this range, your vehicle may need service. Collect as much information
about your
fuel economy as you can find, (miles driven, gallon's of
fuel used, etc.) and provide it to your dealership for their review and
assistance. LA

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.
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.

container,
YOU should look for and use oils containing the following three
things:
SHor SG
“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
(API) levels
of quality.
SAEi 1OW-30
0 Energy 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 svmbol,
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.
