Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your Cadillac dealer before adding equipment
to the
outside
of your vehicle.
Use premium unleaded gasoline rated at 91 octane
or higher. At a minimum,
it should meet specifications
ASTM D48 14 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 9 1, 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 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 wan-anty.
Some gasolines that are
not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl
(MMT):
ask your service station operator whether or not this fuel
contains MMT. General Motors does not recommend the
use of such gasolines. If fuels containing MMT are used.
spark plug life may be reduced and your emission
control system performance may be affected. The
malfunction indicator lamp on your instrument panel
may
turn on. If this occurs, return to your authorized
Cadillac dealer for service.

When you put the cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make
sure
you fully install the cap.
If you need a new cap, be sure to get the right
type. Your dealer can get one for you.
If you get
the wrong type, it may not
fit or have proper
venting, and your fuel tank and emissions system
might be damaged.
