2011 AUDI S8 technical specifications

-Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driving.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time .
(D Note
-Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system .
- Do not use fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its fuel supp lier.
- Do not use fuel for which the contents
cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility of Audi and are not
covered under the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­ l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac ­
turers is carbon deposit build- up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another , they have certain
things in common. All gasoline grades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline brands include additives to keep engine and
Fuel supply and filling your fuel tank 219
fuel systems clean, they are not equally effec ­
tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more info rmation on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadeq uate
fuels, carbon deposit build-ups can rob your
engine of peak performance.
Q) Note
Damage or malfunction due to poor fue l
quality is not covered by the Aud i New Ve­
hicle Limited Warranty.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel fille r flap.
If the power locking system should fail, you
can still open the flap manually -for deta iled
instruct ions see
¢ page 221 .
You can find the fuel tank capacity of your ve­
hicle in
Technical Data ¢ page 282.
The label on the inside of the fuel fi ller flap
tells you the correct fue l for your vehicle. For
more information about fuel specifications,
see
¢ page 218.
Your vehicle fue l tank has an on board refuel­
li ng vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you refuel your vehicle . In order to fill the tank
properly while protecting the environment,
please fo llow this refueling procedure careful­
ly.
_&. WARNING
Under normal operating conditions, never
carry additional fuel containers in your car.
Gas canisters and other containers used to
transport f uel can be dangero us. Such con­
tainers, full or empty, may leak and could
cause a fire in a collis ion. If you must

250 Tires and wheels
contribution to good road ho lding and safe
handling when in good condition and properly
inflated
¢ ,& .
We recommend that all work on tires and
wheels be performed by an authorized Audi
dealer. They are familiar with recommended
procedures and have the necessary spec ial
too ls and spare parts as well as the proper fa­
cilities for disposing of the old tires.
Authorized Audi dealers have the necessary information about technical requ irements for
installing or changing tires and r ims.
Replacing tires and wheels
Tires shou ld be rep laced at least in pairs and
not individually (for example both front tires
or both rear tires together).
Be sure to read and heed the information to
the tire pressure monitoring system*
¢page 256.
Always buy rep lacement radial tires that have
the same specifications as the tires approved
for your vehicle by Audi. Replacement tires
must always have the same load rating speci­
fication as the original equipment or approved optional tires listed in the table
¢page 242.
Audi-approved specification t ires are specially
matched to your vehicle and its load limits,
and can contribute to the important road hold­
ing, driving characteristics, and safety of the
vehicle. The table(¢
page 242) lists specifica­
tions of the tires approved for the Audi mod­
els covered by your Owner's Literature .
The tire pressure label located on driver's side
B-pillar (
¢ page 242, fig. 185) lists the speci­
fications of the orig inal equipment tires in­
stalled on your veh icle at the time it was man­
ufactured.
Federal law requires tir e manufacturers to
place standard ized information on the s ide­
wall of all tires¢
fig. 188 . This information
identifies and describes the fundamental
characterist ics, the quality grade of the tire
and also provides a tire ident ificat ion number for
safety standard ce rtification and in case of
a reca ll.
Tire specifications
Knowledge of tire specificat ions makes it eas­
ier to choose the correct tires. Radial tires
have the tire specifications marked on the
sidewa ll, for examp le:
255/45 R 19 104 H
This conta ins the following information:
P Indicates the t ire is for passenger cars
(where app licab le)
255 Nominal tire width in mm of the tire
from sidewall edge to sidewa ll edge. In
general, the larger the number, the wider
the tire
45 Height/w idth ratio in percent (aspect ra-
t io)
R Tire construction: Radial
19 Rim diameter code (in inches)
104 Loa d rating code
H Speed rat ing letter code
XL (or "xl", "EXTRA LOAD" or "RF") indicates
that the tir e is a "Reinforced" or an "Ext ra
Load" tire
M+S (or "M/S") Indicates that the tire has
some mud and snow capability
The tires could also have the information of
direction of rotation¢
page 238 .
Tire manufacturing date
The manufacturing date is also indicated on
the tire sidewall (possibly on ly on the
inner
side of the wheel):
"DOT ... 2211. .. " means, for example, the tire
was produced in the 22nd week of 2011.
Speed rating (letter code)
The speed rating letter code on the whee ls in­
dicates the maximum permissible road speeds
¢ .&. in Winter tires on page 254.
P up to 93 mph (150 km/h)
Q up to 99 mph (158 km/h)
R up to 106 mph (170 km/h)
S up to 110 mph (180 km/h)
