(D Note
-Me thanol f uels which do not mee t these re­
quirements may ca use corros ion and dam­
age to plastic and rubber components in the
fuel system .
- Do not use fuels that fai l to meet the speci­
fied criter ia in this chapter.
- If you are unable to determine whether or not a particular fuel blend meets the speci­
ficat ions, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identif ied.
- Fuel system damage and performance prob­
lems resulting from the use of fue ls differ­
ent from those specified are not the respon­
s ibility of Audi and are not covered under
the New Veh icle or the Emiss ion Control
System Wa rrant ies.
- If you experience a loss of fue l economy or
driveability and performance prob lems due
to the use of one of these fuel b lends, we
recommend that you switch to unblended
fuel.
Gasoline additives
Applies to: vehicles with gasol ine engine
A majo r concern among many au to manufactur ­
ers is carbon deposit build- up caused by the type
of gasoline yo u use.
A lthough gasoline grades d iffer from one manu­
f a cturer to ano ther, they have cer tain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
pa rts, such as fue l injectors and intake valves . Al ­
though most gaso line brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Aud i recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website (www.toptiergas .com) .
Fuel and R efueling
After an extended period o f using inadeq uate
fuels, carbon deposit bui ld-ups can rob your en­
gine o f peak performance.
(D Note
Damage or ma lf u nction due to poo r fue l qual ­
ity is not covered by the A udi New Vehicle
Limited Warranty .
Diesel fuel
Applies to: vehicles with diesel engine
Always use ULSD (Ultra Low Sulfur Diesel) No. 2 .
The ULSD No . 2 meets the ASTM 0975.
Diesel f uel w it h concen tratio ns of b iod iesel h igh­
er than 5 % such as Bl 1, B20 or BlOO are strict ly
prohibited .
Se rvice station fuel p umps are labe led with the
correct f uel i nfo rmat ion for e asy recog nition by
the user.
If the d iesel f ue l pump is no t labeled
ask the station operator what fuel is being dis­
pensed before fil ling up your vehicle .
UL SD No . 2 m ay not be available ou tside the USA
and Canada . Be su re to check befo re t raveling to
other countries .
UL SD No . 2 c an become thic ke r i n ve ry cold tem­
peratures, and this can imp air the engine's s tart ­
ing and running. Depend ing on the sea son, gas
stations provide ULSD No . 2 that flows better in
cold temperatures so that you can continue oper ­
at ing your vehicle as usual.
@ Note
- Your vehicle's diese l engine was designed
sole ly for use with ULSD No . 2 . Therefo re,
neve r use gasoline, heating oil, other fuels
