Fuel
Use regular unleaded gasoline rated at
87
octane or
gher. 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
weloped 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
still
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 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 qn
your instrument panel may
turn
on and/or your vehicle
may
fail
asmog-check test.
If
this occurs, return
to
your authorized Chevrolet/Geo 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.
