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 Buick dealer before adding equipment
to
the
outside
of
your vehicle.
Fuel
Use regular unleaded gasoline rated at 87 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 is at least
87.
If
the octane is
less than
87,
you may get a heavy knocking noise when
you drive. If it’s bad enough, it can damage your engine.
If you’re using fuel rated
at
87
octane or higher and you
hear heavy knocking, your engine needs service. But
don’t worry if
you
hear a little pinging noise when
you’re accelerating or driving up a hill. That’s normal,
and you don’t have to buy a higher octane fuel
to
get rid
of pinging. It’s the heavy, constant knock that means
you have a problem.
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.
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.
