Owner's Manual
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.

Be sure you have sufficient knowledge,
experience, and the proper replacement
parts and tools before you attempt any
vehicle maintenance task.
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 regular unleaded gasoline rated at 87 octane or higher.
At a.minimum, it should meet specificatiom.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 meting
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 on
your instrument panel may turn on and/or your vehicle
may fail a smog-check test.
If
this occurs, return to your
authorized Chevrolet 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.
