Launch Control
A Launch Control feature is
available, within Competitive Driving
Mode (except Z06 with magnetic
Selective Ride Control or ZR1) or
Performance Traction Management (Z06 with magnetic Selective Ride
Control or ZR1), on vehicles with a
manual transmission to allow the
driver to achieve high levels of
vehicle acceleration in a straight
line. Launch Control is a form of
traction control that manages tire
spin while launching the vehicle.
This feature is intended for use
during closed course race events
where consistent zero to sixty
and quarter mile times are
desirable.
Launch Control is only available
when the following criteria are met:
.Competitive Driving Mode is
selected (except Z06 with
magnetic Selective Ride Control
or ZR1) or any of the
Performance Traction
Management modes are
selected (Z06 with magnetic
Selective Ride Control or ZR1).
The TCS light comes on the
instrument panel and the
appropriate DIC message
displays.
.The vehicle is not moving.
.The steering wheel is pointing
straight.
.The clutch is pressed and the
vehicle is in first gear.
.The accelerator pedal is rapidly
applied to wide open throttle.
The Launch Control feature will
initially limit engine speed as the
driver rapidly applies the accelerator
pedal to wide open throttle.
A smooth, quick release of the
clutch, while maintaining the fully
pressed accelerator pedal, will
manage wheel slip. Complete shifts
as described in Manual
Transmission on page 9‑29.
After the vehicle is launched, the
system continues in Competitive
Mode (except Z06 with magnetic
Selective Ride Control or ZR1) or
Performance Traction Management
(Z06 with magnetic Selective Ride
Control or ZR1).

Fuel
Use of the recommended fuel is an
important part of the proper
maintenance of this vehicle. To help
keep the engine clean and maintain
optimum vehicle performance, we
recommend the use of gasoline
advertised as TOP TIER Detergent
Gasoline.
Look for the TOP TIER label on the
fuel pump to ensure gasoline meets
enhanced detergency standards
developed by auto companies. A list
of marketers providing TOP TIER
Detergent Gasoline can be found at
www.toptiergas.com. TOP TIER
gasoline is only available in the U.S.
and Canada.
The eighth digit of the Vehicle
Identification Number (VIN) shows
the code letter or number that
identifies the vehicle's engine. The
VIN is at the top left of the
instrument panel. SeeVehicle
Identification Number (VIN) on
page 12‑1.
Recommended Fuel
If the vehicle has the 6.2L V8 engine
(VIN Code W), use premium
unleaded gasoline with a posted
octane rating of 91 or higher. You
can also use regular unleaded gasoline rated at 87 octane or
higher, but the vehicle's acceleration
could be slightly reduced, and a
slight audible knocking noise,
commonly referred to as spark
knock, might be heard. If the octane
is less than 87, a heavy knocking
noise might be heard when driving.
If this occurs, use a gasoline rated
at 87 octane or higher as soon as
possible. Otherwise, you could
damage the engine. If heavy
knocking is heard when using
gasoline rated at 87 octane or
higher, the engine needs service.
If the vehicle has the 6.2L V8 engine
(VIN Code T) or the 7.0L V8 engine
(VIN Code E), use premium
unleaded gasoline with a posted
octane rating of 91 or higher. For
best performance, use premium
unleaded gasoline with a posted
octane rating of 93. In an
emergency, you can use regular
unleaded gasoline with an octane
rating of 87 or higher. If 87 octane
fuel is used, do not perform any
aggressive driving maneuvers such

Black plate (46,1)Chevrolet Corvette Owner Manual - 2013 - crc2 - 11/8/12
9-46 Driving and Operating
as wide open throttle applications.
You might also hear audible spark
knock during acceleration. Refill the
tank with premium fuel as soon as
possible to avoid damaging the
engine. If heavy knocking is heard
when using gasoline rated at
91 octane or higher, the engine
needs service.
Gasoline Specifications
At a minimum, gasoline should meet
ASTM specification D 4814. Some
gasolines contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines
containing MMT. SeeFuel Additives
on page 9‑46.
California Fuel
Requirements
If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specifications. See the underhood emission control
label. If this fuel is not available in
states adopting California Emissions
Standards, the vehicle will operate
satisfactorily on fuels meeting
federal specifications, but emission
control system performance might
be affected. The malfunction
indicator lamp could turn on and the
vehicle might fail a smog‐check test.
See
Malfunction Indicator Lamp on
page 5‑18. If this occurs, return to
your authorized dealer for diagnosis.
If it is determined that the condition
is caused by the type of fuel used,
repairs might not be covered by the
vehicle warranty.
Fuels in Foreign
Countries
If planning to drive in countries
outside the U.S. or Canada, the
proper fuel might be hard to find.
Check regional auto club or fuel
retail brand websites for availability
in the country where driving. Never
use leaded gasoline, fuel containing
methanol, or any other fuel not recommended. Costly repairs
caused by use of improper fuel
would not be covered by the vehicle
warranty.
Fuel Additives
To provide cleaner air, all gasolines
in the United States are now
required to contain additives that
help prevent engine and fuel system
deposits from forming, allowing the
emission control system to work
properly. In most cases, nothing
should have to be added to the fuel.
However, some gasolines contain
only the minimum amount of
additive required to meet U.S.
Environmental Protection Agency
regulations. To help keep fuel
injectors and intake valves clean
and avoid problems due to dirty
injectors or valves, look for gasoline
that is advertised as TOP TIER
Detergent Gasoline. Look for the
TOP TIER label on the fuel pump to
ensure gasoline meets enhanced
detergency standards developed by
the auto companies. A list of

Black plate (47,1)Chevrolet Corvette Owner Manual - 2013 - crc2 - 11/8/12
Driving and Operating 9-47
marketers providing TOP TIER
Detergent Gasoline can be found at
www.toptiergas.com.
For customers who do not use TOP
TIER Detergent Gasoline regularly,
one bottle of Fuel System Treatment
PLUS, part number 88861013,
added to the fuel tank at every
engine oil change, can help clean
deposits from fuel injectors and
intake valves. GM Fuel System
Treatment PLUS is the only
gasoline additive recommended by
General Motors. It is available at
your dealer.
Gasolines containing oxygenates,
such as ethers and ethanol, and
reformulated gasolines might be
available in your area. We
recommend that you use these
gasolines, if they comply with the
specifications described earlier.
However, E85 (85% ethanol) and
other fuels containing more than
15% ethanol must not be used in
vehicles that were not designed for
those fuels.Notice:
This vehicle was not
designed for fuel that contains
methanol. Do not use fuel
containing methanol. It can
corrode metal parts in the fuel
system and also damage plastic
and rubber parts. That damage
would not be covered under the
vehicle warranty.
Some gasolines that are not
reformulated for low emissions can
contain an octane-enhancing
additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant
where you buy gasoline whether the
fuel contains MMT. We recommend
against the use of such gasolines.
Fuels containing MMT can reduce
spark plug life and affect emission
control system performance. The
malfunction indicator lamp might
turn on. If this occurs, return to your
dealer for service.Filling the Tank
{WARNING
Fuel vapors and fuel fires burn
violently and can cause injury or
death.
.To help avoid injuries to you
and others, read and follow
all the instructions on the fuel
pump island.
.Turn off the engine when
refueling.
.Keep sparks, flames, and
smoking materials away
from fuel.
.Do not leave the fuel pump
unattended.
.Do not reenter the vehicle
while pumping fuel.
.Keep children away from the
fuel pump and never let
children pump fuel.
