2014 AUDI S6 fuel additives

216 Fuel supply and filling your fuel tank
-Blend must contain not more than 1S%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driv ing.
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.
(CT) 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 fuels that fai l to meet the
specified criteria in this chapter.
- If yo u are unable to determine whether
or not a particular fuel blend meets the
specifications, ask your service station or
its fuel sup plier.
- 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 respons ibility 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.
A lthough gasoline grades differ from one
manufacturer to another, they have certain
things in common. All gasoline g rades contain
substances that can cause deposits to co llect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
brands include additives to keep engine and fuel
systems clean, they a re not equally effec­
tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadequate
f uels, carbon deposit build-ups can rob yo ur
engine of peak performance.
(D Note
Damage or malf u nct ion due to poor fuel
quality is not covered by the Aud i New Ve­
hicle Limited Warranty.
Diesel fuel
Applies to veh icles: w ith diesel engine
Always use ULSD (Ultra Low Sulfur Diesel) sul­
fur content 15 ppm or less.
T he ULSD (U ltra Low Sulfur Diesel) meets the
ASTM-D-97S (grade 2).
Diesel fuel with a higher concentration than
ULSD-Diesel No. 2 ASTM 0975 and Bio-die­
sel with a higher concentration than S
% like
B11, B20 or B100 are strictly prohibited.
Serv ice stat ion fue l pumps a re labeled with
the correct fuel information fo r easy recogn i­
t ion by the user. If the diesel fuel pump is not
labeled ask the station operator what fue l is
being dispensed before filling up your vehicle.
Service stations offering Diesel fuel are gener­
ally located on truck routes or major high­
ways. Directories of Diesel fuel stations are
usually available at Diesel fuel stations.
Some states in the USA req uire permits to
purchase Diesel fuel. Check with your State
Motor Vehicle Department.
Diesel fuel may not be ava ilable outside the
USA and Canada. Be sure to check before trav-
eling to other countries . .,..

222 Fuel supply and filling your fuel tank
Filling AdBlue
Applies to vehicles: with diesel engine
A special refill bottle must be used to fill the
AdBlue .
Fig. 184 Rig ht rear vehicle side: remov ing the Ad B lue
cap
Fig . 185 Ad Blue filler tube: inse rting the refill bottle
The AdBlue fi ller tube is located near the die­
sel filler tube . Always add 1.5 gallons (5. 7 lit­
ers) of AdBlue (three bottles). This is the mini­
mum amount required to ensure the system
detects the refilling and to start the eng ine.
The AdBlue tank capacity is approximately
4 .5 gal lons (17 liters).
Opening the filler tube and adding
AdBlue
Requirement : The request to add Ad Blue must
appear in the instrument cluster display.
• Switch the ignition off .
• Open the tank cover
¢page 218.
• Turn the cap counterclockw ise with the lug
wrench from the vehicle tool kit to remove it
¢fig. 184.
• Remove the cap from the refill bottle.
• Position the refill bottle on the filler tube
and turn the bottle clockwise until it stops
turning
(D ¢ fig . 185.
• Press lightly against the bottom of the bot­
tle @to empty it. Continue pressing the
bottom of the bottle until it is empty or un­
til fluid stops flowing into the tank.
• Turn the bottle to the left without pressing
on the bottom .
Closing the filler tube
• Turn the cap clockwise on the filler tube
with the lug wrench until you hear it tighten
completely .
• Close the tank cover.
After filling
The vehicle must be driven. The system may
take up to two minutes to detect that the
AdBlue has been f illed.
• If there was no Ad Blue left in the tank and a
range of
O mi (0 km) was displayed in the
instrument cluster, switch the ignition on
for about 15 seconds before starting the en­ gine.
A WARNING
= Ad Blue can irritate the sk in, eyes and res-
piratory system. If there is contact with
the fluid, flush immediately with plenty of
water. Consult a physician if necessary.
(D Note
- Only use Ad Blue that conforms to the
standard ISO 22241-1. Do not mix any
additives with the AdBlue and do not d i­
lute it with water.
-A d Blue is not a diesel add itive . Do not
add it to the diesel tank. If Ad Blue is
m ixed with diesel fuel, it can lead to
damage to the engine and the AdBlue
tank system . The Limited New Vehicle
Warranty does not cover such damage.
- Ad Blue attacks surfaces such as painted
vehicle components, plastic and carpet.
Remove the fluid as quickly as possible
w ith a damp cloth and p lenty of cold wa­
ter. If the AdBlue has already crystal-
lized, use warm water and a sponge. .,..
