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.
~ 0 Be sure you have sufficient knowledge,
experience, and the proper replacement
parts and tools before
you attempt any
vehicle maintenance task.
0 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 premium 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 leasf
9 1. 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
MMT. 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 Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may
b.e 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.
