Gasoline fuel
Gasoline grade
A pp lies to: ve hicles w ith gaso li ne engines
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
unlead ed ga soli ne.
Aud i recommends using TOP TIER Detergent Gas­
oline. Additional information on TOP TIER Deter­
gent Gasoline can be found on the official web­
site (www .toptiergas.com) .
The individua l gasoline grades are differentiated
by
oct ane rating s. This value is given with (R +M)/
2 equating to AK I or in RON.
The fo llowing headings match the corresponding
sticker in the fuel fi ller door .
UNLEADED FUEL ONLY MIN. (R+M) /2 87
R egula r/ MIN. RON
91 Regular
Use regu lar gasoline with minim um 87 AKI/
9 1 RON ~@ .
The max imum engine power is only reached if
p rem ium gasol ine 91 AKI/ 95 RON is used.
UNLEADED FUEL ONLY PREMIUM MIN . (R
+M )/2
91 / SUPER MIN. RON 95
Using premium gasoline with m inim um 91 AKI/
95 RON is recommended.
If premium gasoline is not available, you can also
use regula r gasoline 87 AKI/ 91 RON . However
this does reduce the engine powe r slight ly.
CD Note
- Fil li ng the tank just one time with leaded
fuel or other meta llic additives will cause
permanent deteriorat ion 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 engine
l oad can lead to engi ne dam age.

(D Tips
The vehicle can be fi lled with 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 cont aining alcohol or MTBE
(m ethyl tertiary butyl ether )
You may use unleaded gasoline blended with al ­
cohol o r M TBE (commonly referred to as oxygen­
ates) if the blended m ixt ure meets the fo llow ing
c rit eria:
Blend of ga soline 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 than 15% etha-
nol.
Blend of gasoline and MTBE
- Anti -knock index must be 87 AKI or higher.
- Blend mus t contain no t more than 15% MTBE .
Seasonall y adjusted ga soline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iv ing . Du r­
i ng seasonal change-over, we suggest that you
fill up at busy gas stat ions 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
quirements may cause corrosion and dam­
age to plasti c and rubber components in the
fue l system.
- Do not use fue ls that fa il to meet the speci­
fied cr iteria in th is chapter.
...

<( co .... N r--­N .... 0 r--­> co
-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 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 problems 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 lt hough gasoline grades 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.
CD Note
Damage or malfunction due to poor fuel q ual­
ity is not covered by the Aud i New Vehicle
Limited Warranty.
Ch eck ing and Filling
Refueling
Fuel filler neck
The fue l filler neck is located on the rig ht rea r
s ide panel behind the fuel fille r flap .
If the power lock ing system shou ld fail, yo u can
st ill open the flap manually -fo r detailed instruc­
tio ns see
9 page 187.
You can find the fuel tank capacity of your vehicle
i n c:;,
page 251 .
The label on the inside of the f uel fi ller flap tells
you the correct fuel for your vehicle. For more in­
f ormat ion about fuel spec ificat ions, see
9 page 184.
Your vehicle fuel tank has an onboard refue lling
vapor recovery system. This feature helps to pre­
vent fuel vapors from escaping from the tank and
polluting the environme nt wh ile you refue l yo ur
vehicle . In order to fill the tank p roper ly w hile

Audi oil quality standard

A udi reco mmend s
~Castrol I jgl[J,'fE{g ?r,w.:..~J ri, '.IA!,
Audi rec ommends Longlif e high perform ance
engi ne oil from Au di Genuin e Parts
Using the proper engine oil is important for the
functionality and service life of the engine. Your
engine was factory-filled with a h igh-quality oil
which can usually be used throughout the entire
yea r.
(D Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's
Manual and Warranty & Maintenance booklet .
- Use only a high qual ity eng ine oil that ex-
pressly complies with the Audi oil quality
standard specified for your vehicle's engine .
Using any other oil can cause serious engine
damage.
- Do not mix any lubricants or 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 oil quality standard
your engine requires, you may add a total of
no more than 0.5 quart/liter of a h igh-quality
"synthet ic"oil that meets the following speci­
fications.
- Vehicles w ith gasoline eng ine: ACEA A3 or
API SM with a viscosity grade of SAE OW-30,
SAE 5W-30 or SAE 5W-40.
- For more information about engine o il that
has been approved for your vehicle, please
contact either your authorized Audi dea ler
or Aud i Custome r Relat ions at

· Eng ine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all of
its moving parts.
In order to provide effect ive lubricat ion and cool­
i ng of internal engine components, all internal
combust ion eng ines consume a certa in amount
of oil. Oil consumption var ies from engine to en­
gine and may change sign ificantly over the life of
the engine . T ypically, engines w ith a specified
break -in period (see¢
page 65) consume more
oi l during the break-in period than they consume
after oil consumption has stabilized.
U nder normal cond itions, the rate of oil con­
sumption depends on the quality and viscosity o f
the oil , the RPM (revo lutions per minute) at
which the engine is operated, the ambient tem­ perature and road conditions. Further factors are
the amount of o il dilution from water condensa­
tion or fuel residue and the oxidation level of the
o il. As any engine is subject to wear as mileage
builds up, the o il consumption may increase over
ti me unt il replacement of wo rn compo nents may
become necessary.
With all these variables coming into play, no standard rate of o il consumption can be estab­
li shed or spec ified . T he re is no alte rnative to reg­
u la r and freq uent checki ng of the oi l level, see
Note.
If the yellow engine oil level warning symbo l II
in the instrument cluster lights up, you sho uld
chec k the o il level as soon as possible
¢
page 193. Top off the o il at your earlies t con­
venience
¢ page 193.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS
¢page 188.
(D Note
Driving with an insufficient oil level is likely to
cause severe damage to the engine.
