Checking and Filling
Gasoline fuel
Gasoline grade
A pp lies to veh icles: w ith gaso li ne engine
The correct gasoline grade is stated on the inside
of the fuel filler door .
The vehicle is equipped with a catalytic converter
and must only be driven w ith
unleaded ga soli ne.
Aud i recommends using TOP TIER Detergent Gas­
oline. Additional information on TOP TIER Deter­
gent Gaso line can be found on the offic ial web­
site (www .toptiergas.com) .
The individua l gasoline grades are differentiated
by
octane ratings . This value is given with (R +M)/
2 equating to AK I or in RON.
The fo llow ing headings match the co rrespon ding
sticker in the fue l fi ller door .
UNLEADED FUEL ONLY MIN . (R+M) /2 87
Regular/ MIN. RON
91 Regular
Use regu lar gaso line with minim um 87 AKI/
9 1 RON ~@ .
The max imum engine power is only reached if
p rem ium gasol ine 91 A KI/ 95 R ON is used.
UNLEADED FUEL ONLY PREMIUM MIN. (R
+M) /2
91 / SUPER MIN. RON 95
Using premium gasoli ne with m inim um 91 AKI/
9 5 RON is recommended.
If premium gasoline is not available, yo u can also
use reg ula r gasoline 87 AKI/ 91 RON . However
this does reduce t he engine powe r slight ly.
CD Note
- Fil li ng the tank just one ti me with leaded
f u el or other meta llic additives will caus e
p ermanent dete riorat io n to the cata lyt ic
conve rter func tion.
- When gasoline with an octane rati ng that is
too low is used , h igh speeds o r heavy engi ne
l o ad can lead to engi ne d am age.

(D Tips
The vehicle can be fi lled wit h fue l that has a
h igher octane rating than what is requi red by
the eng ine.
Blended gasoline
App lies to vehicles : wit h gasol ine engi ne
U se of g asoline conta ining alcohol or MTBE
(methyl tertiary butyl ether)
You may use unleaded gasoline blended with al ­
cohol o r MTBE (commonly referred to as oxygen­
ates) if the blended m ixt ure meets the fo llow ing
c rit er ia:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- 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 alcoh ol or
ethyl alcohol)
- Anti-knoc k index must be 87 A KI or h igher.
- Blend must not conta in more t han 15% etha-
nol.
Blend of gasoline and MTBE
- Anti -knock index must be 87 AKI or higher.
- Blend mus t contain no t more t han 15% M TBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or s ummer dr iv ing . Du r­
i ng seasonal change-ove r, we s ugges t that you
fill up a t busy gas stat io ns where the seaso nal
adjustment is mo re l ikely to be made in t ime .
CD Note
-Methanol fuels which do not meet these re­
quireme nts may cause cor rosion and dam­
age to plas tic and rubber componen ts i n t he
fue l system.
- Do not use f ue ls that fa il to meet t he speci­
fie d cr iteria in th is ch ap ter.

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 identified.
- Fuel system damage and performance prob­
lems resulting from the use of fue ls diffe r­
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 Warrant ies .
- If you experience a loss of fue l economy or
driveability and pe rformance prob lems due
to the use of one of these fuel blends, we r ecommend that you switch to unblended
fuel.
Gasoline additives
A ma jor concern among many auto manufactur­
ers is carbon deposit build-up ca used by the type
of gasoline yo u use.
A lthough gasoline gr ades d iffer from one manu ­
facturer to another, they have cer tain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves. Al­
though most gasoline 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 Dete r­
gent Gasoline, please go to the official website (www.toptiergas .com) .
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your en­
g ine of peak performance.
(D Note
Damage o r malfunction due to poo r fuel q ual­
ity is not covered by the Aud i New Vehicle
Limited Warranty.
Ch eck ing and Filling
Diesel fuel
Applies to vehicles: wi th diesel engine
Always use U LSD (Ultra Low Sul fur Diesel) No. 2 .
The ULSD No . 2 meets the ASTM D97S.
D iesel f ue l w it h con cen tratio ns of b iod iesel h igh­
er than 5% such as B11, B2 0 or B100 are strictly
prohib ited .
Se rvice station fuel pumps are labe led with the
correct f uel info rmation for easy recog nition by
the user. If the d iesel f uel pump is no t labeled
ask the station operator wha t fu el is being dis ­
pensed before filling up your vehicle .
UL SD No. 2 m ay not be available outside the USA
and Can ada . Be s ure to che ck before traveling to
other countries .
UL SD No . 2 can become thic ke r i n ve ry co ld tem­
peratures, and th is can imp air the engine's s tart ­
ing and running. Depend ing on the season, gas
stations provide ULS D No . 2 that flows be tter in
cold temperatures so that you can continue oper­
at ing your vehicle as usual.
(D Note
- Your vehicle's diese l engine was designed
soley for use w ith ULSD No . 2 . Therefo re,
neve r use gasoline, heating oil, other fuels
or flow imp rovers. These contain substances
that will severely damage the fuel system and the engine . Such damage will not be
covered by yo ur New Vehicle Limi ted War­
ranty .
- If you put a ny amo unt of incorrect fuel in
the fuel tank, do not sta rt the eng ine under
any circumstances. Immed iately contact the
nea res t author ized A udi dealer or author­
ize d Aud i Serv ice Facili ty fo r ass ist ance.
T hese f uels conta in su bstances tha t can se­
verely damage the fuel system an d the en­
gine if the engine is started.
- If the diese l fuel quality is poo r, it may be
necessary to have the wate r drained from
the water sepa rato r in the
fuel filter more
often t han spec ified in the maintenance
schedule. This can help reduce engine mal­
functions <=>

Using the proper engine oil is important for the
functionality and service life of the engine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
yea r.
Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions d ue to failure
to follow rec ommended maintenance and use
requireme nts as s et forth in the Audi Owner's
Manual and Warranty & Maintenance booklet.
- Use only a high quality engine oi l that ex-
pressly complies with the Au di oil quality
standard specified for your vehicle's engine.
Using any o ther oil can cause serious engine
damage.
- Do not mix any lubricants o r other additives
into the engine oil. Doing so can cause en­
gine damage.
@ Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
your eng ine requ ires, you may add a total of
no more than 0 .5 quart/li ter of a h igh-quality
"synthet ic"oil that meets the following speci ­
fications.
- Vehicles with gasoline eng ine: ACEA A3 o r
API SM with a viscosity grade of SAE OW-30,
SAE SW-30 or SAE SW-40.
- Vehicles with diesel eng ine: ACEA C3 or
API CF with a viscosity grade of SAE OW-30
or SAE SW -30.
- For more information about engine oil that
has been approved for your vehicle, please

Engine oil consumption
The engine in your vehicle depends on an ode-
;::: quote amount of oil to lubricate and cool all of
~ its moving parts . co ,....,
~ In order to provide effective lubr ication and cool-,....,
:=: ing of internal engine components, all internal
Ch eck ing and Filling
combustion engines consume a certain amo unt
of oil. Oil consumption varies from engine to en­
gine and may change s ignificantly over the life of
the engine. Typ ically, engines w ith a specified
break-in period (see¢
page 77) consume more
o il during the break-in per iod than they consume
after o il consumption has stab il ized.
Under normal cond itions, the rate of oil con ­
sumption depends on the quality and viscos ity of
the oil, the RPM (revolutions per minute) at
wh ich the engine is operated, the amb ient tem­
perature and road co ndit ions. Further facto rs a re
the amount of oi l di lution from wate r condensa­
tion or fuel resid ue and the oxidat ion level of the
o il. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
time unti l replacement of worn components may
become necessary.
With a ll these variab les coming into play, no
standard rate of oil consumption can be estab ­
li shed or specified. There is no alternative to reg­
u lar and frequent checking of the oi l level, see
Note .
If the yellow engine oil leve l warning symbo l l!I
in the instrument cluster lights up, you should
check the oi l level as soon as possible
¢
page 242. Top off the o il at your earliest con­
venience ¢
page 242.
A WARNING
-Before you check anyt hing in the engine com-
partment, always read and heed all WARN­
INGS
¢page 236.
(D Note
Driving wit h an insufficient oil level is likely to
cause severe damage to the eng ine.
(D Tips
- The oil pressu re wa rning display. is not
an indicator of the oi l le vel. Do not rely on
i t. In stead , check th e oil level in your en­
gine at regular intervals, preferably each
time you refuel, and alway s before goi ng
on a long trip .
