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 .

- Whe n gasoline with an octane rati ng that is
too low is used, high speeds o r heavy engi ne
l oad can lead to engine damage .
(D Tips
The vehicle may be fi lled wi th fu el tha t h as a
higher octane ra ting than wh at is required by

Blended gasoline
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
Yo u may use unleaded gasoline b lended wi th al­
cohol o r MTBE (commonly referred to as oxygen ­
ates) if the blended mixt ure meets the fo llowing
criteria :
Blend of ga soline methanol (wood alcohol or
meth yl alcohol)
- Anti-knock index must be 87 AK I or h igher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more tha n 2% co -solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol )
-Anti -knock index must be 87 AK I or higher .
- Blend must not co ntai n mo re t han
15% etha-
nol.
Blend of ga soline and MTBE
- Anti-knock index must be 87 AKI or higher.
- Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades a re blended to pe rform es­
pec ially well for w in ter o r su mme r dr iv ing . D ur ­
i ng seasonal change-ove r, we s ugges t th at yo u
fill up at busy gas stat ions where the seasona l
adjustment is more likely to be made in time.
(D Note
- Meth ano l fuels which do not meet these re­
q uirements may cause corrosion and dam ­
age to plastic and rubber com ponents in the
fuel system.
- Do not use fue ls that fa il to meet the speci­
fied cr iteria in th is chapter .
-If you are una ble to dete rm ine whether or
not a part icu lar f uel blend meets the speci ­
fications, ask yo ur service station or its fue l
supplier.
- Do not use fue l for which the contents can­
not be ident ified .

-Fuel system damage and performance prob­
l ems resulting from the use of fuels differ­
ent from those specified are not the respon­
sibility of Audi and are not covered under
the New Vehicle or the Emission Control
System Warranties.
- If you experience a loss of fuel economy or
driveability and performance problems due
to the use of one of these fuel blends, we
recommend that you switch to unblended
fuel.
Gasoline additives
A majo r concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasoline grades d iffer from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital engine 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 information on TOP TIER Deter­
gent Gasoline, please go to the official website
(www.toptiergas.com).
After an extended period of using inadequate
fuels, built-up carbon deposits can rob your en­ gine of peak performance.

quality is not covered by the Audi New Vehi ­
cle Limited Warranty.

Using the prope r 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 .
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 Aud i 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.
- ACEA A3 or API SM with a v iscosity grade o f
SAE OW-30, SAE SW -30 or SAE SW-40.
- Fo r more information abou t engine o il t ha t
has been approved for your vehicle, please
contact either your authorized Audi dea ler
or Audi Custome r Relat ions at
1 (800) 822-2834 or visit our web site at
www .audiusa.com or www .aud icanada .ca.
Engine oil consumption
T he engine in your vehicle depends on an ade­
qua te amoun t of oil to lubricate and cool all of
i t s moving par ts.
In order to provide effective lub rication and coo l­
ing of in te rnal engine components, a ll internal
combustion engines consume a cer tain amount
of oil. Oil consumption varies from engine to en ­
g ine and may change sign ificantly over the life of
the eng ine . Typically, eng ines with a spec ified
Ch eck ing and Filling
break-in period (see ¢ page 57) consume more
oi l during th e break-in period than they consume
after oil consumption has stabilized.
Under normal cond itions, the rate of oil con­
sumption depends on the q uality and viscos ity o f
the oil , the RPM (revolutions per minut e) at
which the engine is operated, the amb ient tem­
perature and road condit ions. Further factors are
the amount of oil dilution from w ater condensa­
tion or fuel resid ue and the oxidation level of the
o il. As any engine is subject to wear as mileage
builds up, the oi l consumption may increase ove r
t ime unt il repla cement of worn components may
become necessary.
With al l these variables coming into play, no
standard rate of o il consumption can be estab­
l ished or spec ified . T he re is no alte rnative to reg­
u la r and fre quent chec king of the o il level , see
Note .
If the yellow engine oil level warning symbo l II
in the instrument cluster lights up , you sho uld
check the o il level as soon as possible
¢ page 160. Top off the o il at your earliest con­
venience.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN ­
INGS¢ .&.
in Working in the engine compart­
ment on page 155.
(D Note
D riving wit h an insufficient oil level is likely to
cause severe damage to the engine .
(D Tips
- The oil pressure warn ing display. i s not
an indicato r of the o il le vel. Do not rely on
it . Instead, check the oil level in your en ­
gine at regular intervals , pre fe rabl y each
time you refuel, and alw ays befo re go ing
on a long trip .
-If you have the impression your engine con­
sumes excessive amounts of oi l, we recom­
mend that you consult an author ized Audi
dea ler to have the cause of your concern

@ Fo r the sa ke of the env ironment
- Engine oi l 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.
The engine oil consumption may be up to 0.5 quart/600 m iles (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 dr ives.
Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­
tion.
Before you check anyth ing in the eng ine compart­
ment,
alw ays r ea d and heed all WARNINGS Q .&.
in Working in the engine compartment on
page 155.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
n ance booklet. This is very important because the
l ubri cat ing propert ies of o il diminish gradually
d ur ing normal vehicle use.
Under some c ircumstances the eng ine o il should
be changed more frequently . Change oil more of­
ten if yo u drive mostly short distances, ope rate
the vehicle in d usty areas or under predominant ly
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
l ook da rk 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 p roper disposal, along
with the special tools and necessa ry expertise re­
qu ired, we strong ly recommend that you have
Ch eck ing and Filling
your oi l changed by an authorized Audi dealer or
a qualified service station .
If yo u choo se to ch ange yo ur oil your self, please
note the follow ing important info rmation:
A WARNING
=
To reduce the risk of persona l injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protect ion .
-
-To redu ce the r is k of burns from hot eng ine
oil, let the engine cool down to the touch.
- W hen remov ing the oil d rain plug w ith your
fingers, stay as far away as possib le. Always
keep your forearm parallel to the ground to
he lp prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one la rge enough to hold at
least the tota l 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.
(D Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adverse ly affect yo ur Audi Limited New Vehi­
cle Warranty.
@ For the sa ke of the environment
- Before chang ing your oi l, first make sure
you know where you can properly d ispose of
the used oil.
- Always dispose of used engine o il properly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine o il by tak ing it to a used
eng ine oil collection fac ility in your area, or
contact a service station .
