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
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 deteriorat 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 may be filled with fuel 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 umme r dr iv ing . D ur ­
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.

-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
l ems 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.

Damage or malfunction due to poor fuel q ual­
ity is not covered by the Aud i New Vehicle
Limited Warranty.

Audi recommends Longlife high performance
engine oil from Audi Genuine Parts
Using the proper engine oil is important for the
functionality and s ervice life of the engine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
year .
(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 quality engine 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.
(D 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 qt (0.5 l) of a high-quality
"synthetic"oil that meets the following speci­
fications.
-ACEA A3 or API SM with a viscosity grade of
SAE 0W-30, SAE 5W-30 or SAE 5W-40.
-For more information about engine oil that
has been approved for your vehicle, please
contact either your authorized Audi dealer
or Audi Customer Relations at 1 (800) 822-2834 or visit our web site at
www .audiusa.com or www .audicanada.ca .

· Engine oil consumption
T he engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool oil of
its moving ports .
In order to provide effective lubrication and cool­
ing of internal engine components, all internal
combustion engines consume a certain amount
of oil. Oil consumption varies from engine to en­ gine and may change significantly over the life of
the engine . Typically, engines with a specified
break-in period
(see ¢ page 74) consume more
oil during the break-in period than they consume
after oil consumption has stabilized.
Under normal conditions, the rate of oil con­
sumption depends on the quality and viscosity of
the oil , the RPM (revolutions per minute) at
which the engine is operated, the ambient tem­ perature and road conditions. Further factors are
the amount of oil dilution from water condensa­
tion or fuel residue and the oxidation level of the
oil. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
ti me until replacement of worn components may
become necessary.
With all these variables coming into play, no standard rate of oil consumption can be estab­
lished or specified . There is no alternative to reg­
ular and frequent checking of the oil level , see
Note.
If the yellow engine oil level warning symbol II
in the instrument cluster lights up, you should
check the oil level as soon as possible
¢ page 321. Top off the oil at your earliest con­
venience
¢ page 321.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS
¢ page 316.
(D Note
Driving with an insufficient oil level is likely to
cause severe damage to the engine.
IJII,

Checking and Filling
CJ) Note
-The engine oil level must not be under the
marking
(D r=> fig. 272, because this increas­
es the risk of engine damage.
- After adding engine oil, the oil level must
not be above the marking
@ c:> fig . 2 72, be­
cause this increases the risk of catalytic con­
verter and/or engine damage. Do not start
the engine. Contact an authorized Audi
dealer or authorized Audi Service Facility to
have excess engine oil extracted if necessa­
ry .
- Do not mix any additional lubricants into
the engine oil. Damage caused by such addi­
tives is not covered by the warranty .
@ For the sake of the environment
-Engine oil should never enter the sewer sys­
tem or come into contact with the ground under any circumstances.
- Pay attention to legal requirements when
disposing of empty oil containers.
@ Tips
The engine oil consumption may be up to
0 .S quart/600 miles (0.5 liter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumption may be higher during the
first 3,000 miles (5,000 km). The engine oil
level must be checked regularly. It would be
best to check each time you refuel your vehi­
cle and before long drives.
Changing the engine oil
We recommend that hove your oil changed by on
authorized Audi d eal er or o qualified s ervice sta­
tion.
Before you check anything in the engine compart­
m ent,
always read and heed all WARNINGS
r=> page 316.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance bookl et. This is very important b ecause the
lubric ating properties of oil diminish gradually
during normal vehicle use.
322
Under some circumstances the engine oil should
be changed more frequently. Chang e oil more of­
ten if you drive mostly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traffic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods .
Detergent additives in the oil will make fresh oil
look dark after the engine has been running for a
short time . This is normal and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposal, along
with the special tools and necessary expertise re­
quired, we strongly recommend that you have
your oil changed by an authorized
Audi dealer or
a qualified service station .
If you choose to change your oil yourself, please
note the following important information :
,&. WARNING
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot engine
oil , let the engine cool down to the touch.
- When removing the oil drain plug with your
fingers, stay as far away as possible . Always
keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one large enough to hold at
least the total amount of oil in your engine.
- Engine oil is poisonous . Keep it well out of
the reach of children.
- Continuous contact with used engine oil is
harmful to your skin . Always protect your
skin by washing oil off thoroughly with soap
and water .
0 Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adversely affect your Audi Limited New Vehi­
cle Warranty .
