I A CAUTION:
You can be injured and your vehicle could be
damaged if
you try to do service work on a
vehicle without knowing enough about it.
Be sure you have sufficient knowledge,
experience, and the proper replacement
parts and tools before you attempt any vehicle maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “English’ and “metric”
fasteners can be easily confused. If you use
the wrong fasteners, parts can later break
or fall off. You could be hurt.
Fuel
Use premiurn unleaded gasoline rated at 91 octane or
higher.
At a minimum, it should meet specifications ASTM
D4814 in the United States and CGSB 3.5-M93 in Canada.
Improved gasoline specifications have been developed by
the American Automobile Manufacturers Association
(AAMA) for better vehicle performance and engine
protection. Gasolines meeting the
AAMA specification could provide improved driveability and emission control
system protection compared to other gasolines.
Be sure the posted octane for premium 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 a lower octane
-- as low as 87 -- if heavy
knocking does not occur.) If you’re using
91 or higher
octane unleaded gasoline and you still hear heavy
knocking, your engine needs service.
If your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label),
it is designed to operate on fuels that meet California
specifications. If such fuels are not available
in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on
your instrument panel may
turn on and/or your vehicle
may fail a smog-check test. If this occurs, return to your
authorized Cadillac dealer for diagnosis to determine the
cause
of failure. In the event it is determined that the
cause of the condition is the type of fuels used, repairs
may not be covered by your warranty.

In Canada, some gasolines contain an octane-enhancing
additive called
“T. If you use such fuels, your
emission control system performance may deteriorate
and
the malfunction indicator lamp on your instrument
panel may turn on. If this happens, return
to your
authorized Cadillac dealer for service.
To provide cleaner air, all gasolines are now required to
contain additives that will help prevent deposits from
forming
in your engine and fuel system, allowing your
emission control system
to function properly. Therefore,
you should not have to add anything to the fuel. In
addition, gasolines containing oxygenates, such as ethers
and ethanol, and reformulated gasolines may be
available
in your area to help clean the air. General
Motors recommends that you use these gasolines if they
comply with
the specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. 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.
Fuels in Foreign Countrics
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended in
the previous text on fuel. Costly repairs
caused by
use of improper fuel 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).
