Downloaded from www.Manualslib.com manuals search engine The 8th digit of your vehicle identification number
(VIN) shows the code letter for your engine. You will
find the VIN at the top left of your instrument panel.
(See “Vehicle Identification Number” in the Index.)
If
you don’t have the 5.7L Code P engine, use regular
unleaded gasoline rated at 87 octane or higher.
If you have the
5.7L Code P engine, use premium
unleaded gasoline rated at 91 octane or higher for best
performance. You may use middle grade or regular
unleaded gasolines, but your vehicle may not accelerate
as well.
At
a minimum, the gasoline you use 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 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 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.

painted surfaces as soon as possible. See “Cleaning the
Outside
of Your Chevrolet” in the Index.
When you
put the cap back on, turn it to the right until
you hear at least three clicks. 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 and your fuel tank
and emissions system might be damaged.
Checking Things Under the Hood
I A CAUTIC 1: I
-
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan.
Things that burn can get on hot engine parts and
start
a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or others
could be burned. Be careful not to drop or spill
things that will burn onto
a hot engine.
