Your fuel gage bars light up when the-
ignition ken, -or if the ignition is off,
wken you turn on your.parking lights,
to’ show you about how much fuel you
have left..
When the normal display -is ,down to .the
last
two bars, the message RESERVE
will appear on the left of the-:gag.e.
Here are threethings that some owners
ask about. None of these show a
problem with your bel gage:
At. the gas station, the gas pump shuts
.off be€ore the gage reads F (Full).
It takes a little more or. less fu.el to fill
up than the gage indicated. For
.example., the gage may have. indicated
-t-he tank was half full, but it actually
t0.olr.a 1.ittle more or. less than half the
tanlr’s capacity to ‘fill the tank.
The gage moves a lit& whmyau turn
.a c-arner or spee.d up.
For your fuel tank cap,acity, see Service
Station Information an the last page of-
this manual.

Fael
Use premium ,unleadedgasohe rated at
91 octane higher, You may use
middle grade or rcgultir unleaded
gasolines, but-
your vehicle may not
accelerate as
well. The gasoline you use
should meet specifications ASTM
D4814 inthe US. and CGSB 3-5-92 in
Canada. These fuels should have the
proper additives, so you should not
have
to add- mything’to the fuel.
In the US. and Canada, it’s easy to be
sure. you get the right lrind of gasoline
(unleaded). You’ll
see “UNLEADED”
right QII 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 leatit 89 €or middle-
grade and 87 for regular). If the octane
is less than 87, yuu may get a heavy
knocking nu& when you drive. I€. it’s
bad enough, it
can damage YOLK engine.
If you’re usingfuel rated at 91 octane or
higher and you still hear heavy
knocking, your engine needs service.
But don’t wq 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.
Fuel Capacity: 20 U. S. Gallons
(75.7 L) . Use unleaded he1 only.

Two labels on your vehicle show how
much weight
it may properly carry. The
Tire-Loading Information label found
on
the rear edge of the driver's door
tells
you the proper size, speed rating
and recommended inflation pressures
€or the tires
on your vehicle. It also
gives you impartant information about
the number
of people that can be in
your vehicle and the total weight that
you can carry. This weight is called the
Vehicle Capacity Weight and includes
the weight of all occupants, cargo, and
all nonfactory-installed options. The other
label is the Certification label,
also on the rear
edge of the driver's
door. It
tells you the gross weight
capacity of
your vehicle, called the
GVWR (Gross Vehicle Weight Rating).
The
GVWR includes the weight of the
vehicle, all occupants, fuel and cargo.
Never exceed the GVWR
for your
vehicle, or the Gross Axle Weight
Rating
(GAWR) for either the front or
rear axle.
And, if you do have a heavy load, you
should spread it out. Don't carry more
than
100 lbs. (45 kg) in the rear area of
your Corvette.
