Gasoline
Fuel supply
Applies to: vehicles with gaso line engine
Using the right fuel helps keep the environment
clean and prevents engine damage.
F u el r eco mmend ati on
The fuel recommended for your vehicle is unle ad­
e d pr em ium
grade gasoline . Audi recommends
using TOP TIER Detergent Gasoline with a mini­
mum octane rating of 91 AKI (95 RON). For more
information on TOP TIER Detergent Gasoline,
p lease go to the offic ial website
(www.toptiergas .com).
The recommended gasoline octane rating for
your engine can also be found on a label located on the ins ide of the fuel filler flap . This rating
may be specified as AK I or RON .
Your veh icle may also be operated using unlead­
ed regular gasoline with a minimum octane rat ­
ing of 87 AKl/91 RON. However, using 87 AKI/91
RON octane fuel w il l slightly reduce engine pe r­
forma nce.
Us e un leade d gaso lin e onl y. Unleaded gasoline
is availab le throughout the USA , Canada, and in
most European countries . We recommend that
you do not ta ke your vehicle to areas or co unt ries
where un leaded gaso line may not be availab le.
For more information on refueling your vehicle,
see
¢page 192.
Octan e rating
Octane rating indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignit ion and detonation . Therefore, buy ing
the correct grade of gasoline is very important to
he lp prevent poss ible engine damage and a loss
of eng ine performance.
Gasoline most commonly used in the Un ited
States and Canada has the following octane rat­
i n gs that ca n usually be found on the filler pump:
- Premium Grade: 91 - 96 AKI
190
- Regu la r Grade: 87 - 90 AK I
Explanation of the abbreviations:
AKI = Anti Knock Index = (R +M)/2 = (RON +MON)/
2
RON = Research Octane Number
MON = Motor Octane Number.
{[) Note
-Do not use a ny fue l w ith o ctane ratings low­
er than 87 AKI or 91 RON othe rw ise expen­
sive engine damage wi ll occur .
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your vehi­
cle's catalyt ic converter and its ability to
control exhaust emissions .
Blended gasoline
Applies to: vehicles with gasoline engine
Use of gaso lin e conta ining alcoho l or MTBE
(meth yl tertia ry butyl ether )
You may use unleaded gasoline blended with al­
cohol or MTB E (commonly referred to as oxygen ­
ates) if the blended m ixture meets the follow ing
criteria:
Blend of g asoline methanol (wood alcohol o r
m eth yl alcoho l)
-Anti -knock index must be 87 AKI or h igher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more than 2% co -solvents.
Blend of ga soline and ethanol (grain alcohol or
ethyl alc ohol )
- Anti-knock index must be 87 AKI or h igher .
- Blend must not conta in more than 15% etha-
nol.
Blend of gas oline and M TBE
- Anti-knock index must be 87 AK I or h igher .
- Blend must contain not mo re than 1S% MTB E.
S easonall y adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iv ing . Dur-
i ng seasonal change-over, we suggest that you .,..

(D Note
-Methanol f uels which do not mee t these re­
quirements may ca use corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fai l to meet the speci­
fied criteria in this chapter.
- If you are unable to determine whether or not a particular fuel blend meets the speci­
fications, 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 problems due
to the use of one of these fuel b lends, we
recommend that you switch to unblended
fuel.
Gasoline additives
A ma jo r concern among many auto manufactur ­
e rs is carbon deposit build-up caused by the type
of gasoline you use.
A lthough gasoline grades d iffer from one manu ­
facturer to ano ther, they have certain things in
common . All gasoline grades contain substances
that can cause deposits to collect on v ita l eng ine
parts, such as fuel injectors and intake valves. Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Audi 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) .
Check ing and Filling
After an extended period of using inadeq uate
fuels, carbon deposit bui ld-ups can rob your en­
gine of peak performance.
(D Note
Damage or ma lf u nction due to poor fuel 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 fuel w it h concentrations 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 info rmation for e asy recog nition by
the user.
If the d iesel fue l pump is not 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 sure to check befo re t raveling to
other countries .
UL SD No . 2 can become thic ke r i n ve ry cold tem­
peratures, and th is 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
soley for use with ULSD No . 2 . Therefore,
neve r use gasoline, heating oil, other fuels
or flow improvers. These contain substances
that will severely damage the fuel system
and the engine . Such damage will not be
cove red by your New Vehicle Limited War­
r a nty.
- If you put a ny amo unt of incorrect fuel in
the fuel tank, do not sta rt the eng ine under
any circumstances. Imme diately contact the
nea res t a uthor ized Audi dealer or author­
ized Aud i Serv ice Facility fo r ass istance .

vapor recovery sys tem . This fea tu re he lps to pre­
vent fuel vapors from escaping from the tank and pollut ing the env ironment while you refuel your
ve hicle. In order to fill the tank prope rly while
p rotecting the environment, please fo llow this
re fueling proce dure caref ully.
