Your fuel gauge shows about how much fuel is in your
tank. The bars light up when the ignition is on or, if the
ignition is off, when
you turn on your parking lamps.
When the display
is down to the last two bars,
RESERVE will appear next to the gauge.
Here
are three concerns some owners have had about the
fuel gauge. All these situations
are normal and do not
indicate that anything is wrong with the fuel gauge.
At the gas station, the fuel pump shuts off before the
gauge reads
FULL (F).

do your own service work, see “Servicing Your Air
Bag-Equipped Corvette” in the Index.
You ;should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. See “Maintenance Record” in the Index.
NOTICE:
If you try to do your own service work without
knowing enough about it, your vehicle could be
damaged.
Fuel
5.7L LT5 (Code J) 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.)
Use premium unleaded gasoline rated at
9 1 octane or
higher. You may use middle grade or regular unleaded
gasolines, but your vehicle may not accelerate as well.
The gasoline you use should meet specifications ASTM
D4814 in the United States and CGSB 3.5-92 in
Canada. These fuels should have the proper additives,
so
you should not have to add anything to the fuel.
In the United States and Canada, it’s easy to be sure you
get the right kind
of gasoline (unleaded). You’ll see
UNLEADED right on
the pump. And only unleaded
nozzles will fit into your vehicle’s filler neck.

Downloaded from www.Manualslib.com manuals search engine Gasolines for Cleaner Air
Your use of gasoline with deposit control additives will
help prevent deposits from forming in your engine and
fuel system. That helps keep your engine in tune and
your emission control system working properly. It’s
good for your vehicle, and you’ll be doing your part for
cleaner air.
Many gasolines
are now blended with oxygenates.
General Motors recommends that you use gasolines with
these blending materials, such as MTBE and ethanol. By
doing
so, you can help clean the air, especially in those
parts of the country that have high carbon monoxide
levels.
In addition, some gasoline suppliers are now producing
reformulated gasolines. These gasolines
are specially
designed to reduce vehicle emissions. General Motors
recommends that you use reformulated gasoline. By
doing
so, you can help clean the air, especially in those
parts of the country that have high ozone levels.
You should ask your service station operators if their
gasolines contain deposit control additives and
oxygenates, and if they have been reformulated to
reduce vehicle emissions.
5.7L LT1 (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. The gasoline you use should meet
specifications
ASTM D4814 in the United States and
CGSB
3.5-92 in Canada. These fuels should have the
proper additives,
so you should not have to add anything
to the fuel.
In the United States and Canada, it’s easy to be sure you
get the right kind of gasoline (unleaded). You’ll see
UNLEADED right on the pump. And only unleaded
nozzles will fit into your vehicle’s filler neck.
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 91 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.
