The engine oil used must conform to exact
specifications.
T he service interva l d isp lay in the instrument
cluster of yo ur vehicle will inform you when it
is time for an oil change. We recommend that
you have your oil changed by an authorized
Audi Serv ice Advisor .
If you have to top off the oi l between oi l
changes, use the Audi o il quality standard

228 Check ing and filling
Using the proper engine o il is important for
the functionality and service life of the en­
g ine. Your engine was factory-filled with a
h igh-quality oil which can usua lly be used
throughout the entire year.
0 Note
Your L imited New Vehicle Warranty does
not cover damage or ma lfunctions due to
fai lure to follow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Ma intenance booklet.
- Use only a high quality eng ine oil that ex­
pressly complies w ith the Audi o il quality
standard spec ified for your veh icle's en­
gine. Using any other oil can cause seri­
ous eng ine damage.
- Do not mix any lubricants o r othe r addi­
tives into the eng ine o il. Doing so can
ca use engine damage.
If you need to add oi l and there is no ne
availab le tha t mee ts the Audi oil qua lity
s tandard your engine requires, yo u may
add a tota l of no more than 0 .5 quart/liter
of a high-quality "synthetic"oil that meets
the following specifications.
- Vehicles with gaso line engine: ACEA A3
or API SM with a viscosity grade of
SAE 0W-30, SAE SW-30 or SAE SW-40.
- Vehicles with diesel engine: ACEA C3 or
API CF with a v iscosity grade of
SAE 0W-30 or SAE SW-30.
- For more information abo ut eng ine oil
that has been approved for your vehicle, please contact either your a uthorized
Audi dealer or Audi Customer Relations
at 1 (800) 822-2834 or visit our web site

Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool all
of its moving ports .
In order to provide effective lubricat ion and
cooling of interna l eng ine components, all in­
ternal combust ion e ngines consume a certain
amount of oil. Oil consumpt ion va ries from
engi ne to engine and may change sig nifican tly
over the life of the engine. Typically, engines
with a spec ified break -in period (see
c> page 203) consume more oil during the
break-in period than they cons ume after oi l
consumption has stabilized.
U nder normal cond itions, the rate o f oi l con ­
s u mption depends on the q uality and viscos ity
of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road conditions. Further fac­
tors are the amount of oil dilut ion from water
condensation or fue l residue a nd the oxida­
t ion level of the oil. As any eng ine is subject to
wea r as m ileage builds up, t he oil co nsump ­
t ion may increase over time until replacemen t
of worn components may be come necessary.
With a ll these variab les coming into play, no
standard rate of oil consumpt io n can be es­
tabl ished o r spe cified . There i s no alte rnative
to regu lar and frequent che ck ing of the o il lev ­
el , see
Note.
If the yellow engine oil leve l wa rning symbo l

@ Tips
-The oil pressure warning display. i s
not an indicator of the oil level. Do not
rely on it. Instead , check the oil level in
your engine at regular intervals, pref­
erably each time you refuel , and always
before going on a long trip .
-If you have the impression your engine
consumes excessive amounts of oil, we r ecommend that you consult your Audi
dealer to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate measurement of oil con­
sumption requires great care and may
take some time. Your Audi dealer has in ­
structions about how to measure oil con­
sumption accurately.

230 Check ing and filling
- If your skin has come in contact with the
engine oil, you must subsequently
cleanse it thoroughly.
- Check the oil leve l using the MMI. If the

@ For the sake of the environment
- Under no circumstances can the oil come
in contact with the sewage network or
the soil.
- Observe and follow lega l regu lations
when disposing of empty oil containers.
Changing the engine oil
We recommend tha t have your oil changed by
an authorized Audi dealer or a qualified serv ­
ice station .
Before you check anything in the engine com­
partment,
alway s read and heed all WARN­
INGS
~ .& in Working in the engine compart­
ment on page 225 .
The engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance booklet . This is very important
because the lubricating properties of oil di­
minish gradua lly dur ing no rmal veh icle use .
Under some circumstances the engine o il
should be changed more frequently . Change
oil more often if you drive most ly short dis­
tances , ope rate the vehicle in dusty areas or
under predominantly stop-and-go traffic con­
d itions, or have your veh icle where tempera­
tures remain below freezing fo r ex tended pe ­
riods .
Detergent addit ives in the o il w ill ma ke fresh
oil look dark after the eng ine has been run- ning for a sho
rt 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 specia l tools and necessary ex­
pertise req uired, we strongly recommend that
you have your oil changed by an a uthorized
Aud i deale r or a qualified service station.
If yo u choo se to chan ge your oil yours elf ,
please note the fo llowing important informa ­
t ion:
A WARNING
=
To reduce the risk of personal injury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protect ion.
- To reduce the risk of burns from hot en-
g ine oil, let the engine cool down to the
touch.
- When removing the oil dra in p lug with
your fingers, stay as far away as possible.
Always keep your forearm parallel to the
ground to help prevent hot oil from run­n ing down you r arm.
- Dra in the oil into a container designed
for this purpose, one large enough to hold at least the tota l amount of o il in
your engine .
- Engine oil is poisonous . Keep it wel l out
of the reach of children.
- Continuous contact with used eng ine o il
is harmful to your sk in . Always protect
your skin by washing oil off tho roughly
wit h soap and wate r.
(D Note
Neve r mix oil additives with you r engine
oi l. These additives can damage your en­
gine and adversely affect your Audi Limit­
e d New Veh icle War ranty.
@ For the sake of the environment
- Before changi ng your oil, first make su re
you know where you can prope rly dispose
o f the used oil. ..,.
