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).

Downloaded from www.Manualslib.com manuals search engine Your vehicle  has an air  bag system. Before attempting to 
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.

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.
