2013 AUDI S8 open gas tank

-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 229
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 malf unct ion 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 231.
You can find the fuel tank capacity of your ve­
hicle in
Technical Data ¢ page 292.
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 228.
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 collision. If you must

transport fuel to use for your lawn mower,
snow blower, etc., be very careful and al­
ways observe local and state laws regard­
ing the use, transportat ion and storage of
such fuel containers. Make certain the con­
tainer meets industry standards (ANSI/
AS TM F852 -86) .
(D Note
Never drive your vehicle until the fuel tank
is completely empty. The irregular supply
of fuel can cause misfiring. Gasoline could
enter the exhaust system and damage the
catalyt ic converter.
Refuelling
Fig. 190 Right rear vehicle side: Opening the fuel filler

and hang it on the fuel filler flap¢
fig. 191.
Refuelling procedure
~ Insert the fu el nozzle from the gasoline
pump into the fuel filler neck as far as it will
go .
~ Select a medium refuelling rate so that the
nozzle switches off automatically when the
tank is full.
Putting the fuel cap back on
~ After fi lling your tank, twist the fuel filter
cap clockwise as far as it w ill go.

A WARNING
Improper refue ling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injur ies.
- Failure to shut the engine
off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filter neck could cause
fuel to spray out of filler neck or to over­
flow. Fuel spray and overflowing fuel can
cause a fire.
- Never use a cellular telephone while re­
fue ling. The electromagnet ic rad iat ion
can cause sparks that can ignite fuel va­
pors and cause a fire.
- Never get back into your vehicle whi le re­
fueling.
If in exceptional circumstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge
static electricity before touching the fill­
er nozzle again. Static electricity can
cause sparks that can ignite fuel vapors
released during refueling.
- Never smoke or have an open flame any­
where in or near your veh icle when refu­
eling or filling a portable fuel container.
- For your safety, we strongly recommend
that you do not travel with a portable
