the date
of any service work you perform. See “Maintenance Record” in
the Index.
n
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

get heavy knocking, your engine needs service.
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 Cadillac.
Ethanol is ethyl or grain alcohol. Properly-blended fuel that is no more
than
10% ethanol is fine for your Cadillac.
I 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 “cosolvents” 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 designed to reduce vehicle
emissions. General Motors reco.mmends that you use reformulated
gasoline. By doing
so, you can help clean the air, especially in those parts
of the country that have high ozone levels.

Downloaded from www.Manualslib.com manuals search engine - 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.
- 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.

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
