I NOTICE:
If you try to do your own service work without knowing enough
about it, your vehicle could be damaged.
FUEL
Use premium unleaded gasoline rated at 91 octane or higher. It should
meet specifications
ASTM D4814 in the U.S. and CGSB 3.5-92 in
Canada. These fuels should have the proper additives,
so you should not -
have to add anything to the fuel.
In the U.S. and Canada, it’s easy to be sure you get the right kind
of
gasoline (unleaded). You’ll see “UNLEADED” right on the pump. And
only unleaded nozzles will fit into your vehicle’s filler neck.
Be sure the posted octane is at least
91. If the octane is less than 91, you
may get
a heavy knocking noise when you drive. (In an emergency, you
may be able to use lower octane
-- as low as 87 -- if heavy knocking does

deposit control additives and oxygenates, and
if they have been
reformulated to reduce vehicle emissions.
- FUELS IN FOREIGN COUNTMES
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.

Your fuel economy (miles per gallon or liters per 100 kilometers) can vary

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

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 adjustment.s make the mileage
estimates correspond more closely to the actual fuel economy realized by
the average driver.
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;
0 Combine errands into one trip.
0 Turn the engine off rather than letting it idle for more than a minute.
