CAUTION: (Continued)
D
Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
Adding Equipment to the Outside of
Your Vehicle
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 dealer before adding equipment to the outside of
your vehicle.
Fuel
Use premium unleaded gasoline rated at 91 octane or
higher. It is recommended that the gasoline meet
specifications which have been developed by the
American Automobile Manufacturers Association
(AAMA) and endorsed by the Canadian Motor Vehicle
Manufacturers Association for better vehicle performance
and engine protection. Gasolines meeting the AAMA
specification could provide improved driveability and
emission control system performance compared to other
gasolines. For more information, write to: American
Automobile Manufacturer's Association, 7430 Second
Ave, Suite 300, Detroit MI 48202.
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
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 emission control
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. (See "Malfunction
Indicator Lamp" in the Index.) If this occurs, return to
your authorized Buick 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.
