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 for premium is at least
91 (at
least
89 for middle grade and 87 for regular). 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 the recommended 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 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.
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 his 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
Chevrolet dealer for service.

(counterclockwise). The cap has a spring in it;
if you let
go of the cap too soon, it will spring back to the right.
BN:
If you get gasoline on yourself and then
something ignites
it, you could be badly burned.
Gasoline can spray out on you if you open the
fuel filler cap too quickly. This spray can happen
if your
tank is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait for any “hiss” noise to stop. Then unscrew
the cap all the
way.
Be careful not to spill gasoline. Clean gasoline from
painted surfaces
as soon as possible. See “Cleaning the
Outside of Your Vehicle” in the Index. 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. The diagnostic system
can determine if the fuel cap has been left off
or
improperly installed. This would allow fuel to
evaporate into the atmosphere. See “Malfunction
Indicator Lamp” in the Index.
NOTICE:
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 properly. This may
cause your malfunction indicator lamp to light
and your fuel tank and emissions system may be
damaged. See “Malfunction Indicator Lamp” in
the Index.
