Engine oil
Engine oil specifications
The engine in your Audi needs the righ t kind
of oil.
The engin e in your Audi is a sophisticated
powerpl ant that was bu ilt to exacting spe cifi­
cations . Thi s engine needs the righ t kind of
engine oil that meets specification s regarding
quality and v iscosity so that it can run
smoothly and reliably . Choosing the right oil
and changing oil within the tim e and mileage
intervals printed in you r vehicle's Warra nty
&
Maintenance booklet matters a lot more to­
day than it did years ago . Audi has developed
a special quality standard for engine oil that
will h elp assur e that your vehicle's engine wi ll
get the lubr ication it need s for proper opera -
tion. ..,.

Modern eng ine lubrication has taken a quan ­
tum leap in the last few years . Many synthetic
oils available today provide better engine lu­
brication that can outlast traditional petrole­
um-based oils, making them a smart choice
for use throughout the life of your Audi.
Whether you use synthetic or petroleum­
based engine oil, the oil that you use must
conform to Audi's oil quality standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (veh icles with diesel engine) to
he lp keep your vehicle's eng ine running
smoothly and help prevent the fo rmation of
harmf ul depos its, sometimes ca lled "sludge,"
that over time can lead to expensive repairs.
At the time of pr inting, engine o ils availab le in
the U.S. and Canada tha t meet the exacting
specifications of A udi oil standard VW 502 00
(vehicles with gaso line engine) or VW 50 7 00
(vehicles with diesel engine) are synthetic en­
gine oils . This does not mean, however, that
every synthetic engine oil will meet Aud i oil
standard VW 502 00 (vehicles with gasoline
engine) or VW 507 00 (vehicles w ith diese l
engine). So always be sure that you use an ap­
proved oil.
To help prevent the formation of harmful de­
posits use only oil with the follow ing spec ifi­
cations printed on t he oil container:
- Aud i oil standard VW 502 00 (gasoline en ­
gine )
- Aud i oil standard VW 50 7 00 (d iesel en -
gine )
Oil conta iner labe ls may carry the specif ica ­
tion singly or in comb ination with other desig­
nations and oil qua lity standards.
Vi scosi ty
Eng ine oils are graded acco rding to their v is­
cosity. The prope r viscosity grade oil for your
engine depends on cl imac tic or seasonal con­
d itions where you dr ive. You can use oi l with a
viscosity grade of SAE SW40 across all tem ­
pe rat ure ranges for normal d riving conditions .
H oweve r, if eng ine oi l viscosity grade
SAE SW40 is not ava ilable, you can a lso use
Checkin g and fillin g 22 7
viscosity grade SAE 5W -30 or SAE OW-40 as
long as it meets Audi oil q uality standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles w ith diese l eng ine) spec­
ifications.
Because engine oil that meets the Audi oi l
standard may not be available everywhere
when you need it, we strongly recommend
that you always carry with you an extra quart
( li ter) of oil that express ly conforms to the
VW 502 00 (veh icles with gasoline engine) or
VW 507 00 (vehicles w ith d iese l eng ine) spec­
ification, in case you have to top off the oil
wh ile on the road.
App lie s to vehicle s with gasoline engin e on­
l y:
Only if the level of the o il is at or below the
minimum ma rk on the o il dipstick -and no oi l
that expressly conforms to Audi o il st andard
VW 502 00 spec ificat ions is available - may
you top off with a high quality engine o il, pre f­
erably synthetic -based, that meets ACEA A3
or API SM specificat ions, but even then, only
in v iscosity grades SAE SW-40, SAE SW-30, or
SAE OW-40. However, during the entire time
between oil change intervals, never top off
with more than a total of 0 .5 qt/liter engine
o il that does not conform to Audi o il specifica­
tion VW 502 00.
App lie s to vehicles with die sel engin e only:
Only if the level of the o il is at or below the
min imum ma rk on the o il dipstick - and no oi l
t h at exp ressly conforms to Audi o il standard
VW 507 00 spec ificat ions is available - may
you top off with a high quali ty engine o il, that
meets ACEA C3 or API CF specifications, but
even t hen, only in viscosity grades SAE
SW-40, SAE 5W-30, or SAE OW-40. However,
during the entire time between oil change in­
terva ls, never top off with more than a total
of 0. 5 qt/liter engine oil that does not con-
for m to Aud i oil spec ification VW 50 7 00.

names etc.) that conform to Aud i oi l standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine).
C hang in g th e en gin e oil
The engine oil and o il filter must be changed
according to the m ileage (ki lomete rs) and
time inte rva ls spec ified in your vehicle's War­
ranty
& Maintenance booklet . Do not exceed
these intervals - harmful deposits from old
engine o il can reduce engine performance and
can lead to expensive engine repairs .
Changing the oil at the recommended inte r­
va ls is so very important because the lubricat­
ing properties of oi l decrease grad ually during
norma l vehicle use. If you are not sure when
you have your oil changed, ask your author­
ized Audi Service Advisor .
Under some circumstances the engine o il
should even be changed more frequently .
Change oil more often if you drive mostly
short d istances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
d itions, or when you use your vehicle where
temperatures stay below freezing point fo r
l ong periods.
Detergent add it ives in the o il w ill make fresh
oil look dark after the eng ine has been run­
n ing fo r a short time. This is no rma l and is not
a reason to change the o il more often than
recommended.
Dama ge or ma lfun cti ons du e to la ck of
maint enan ce
It is essential that you change your oil at the
recommended intervals using only engine oil
that complies with Audi oil standard
VW 502 00 (vehicles wi th gaso lin e engine) or
VW 507 00 (veh icles with diese l engine) . Yo ur
Limited New Vehicle Warranty does not cover
damage or ma lf u nctions due to failure to fol­
low recommended maintenance and use re­
qu irements as set forth in the A udi Owner's
Manual and War ranty
& Maintenance book let.
Your dea ler will have to deny warranty cover­
age unless you present to the dealer proof in the form o
f Service or Repair Orders that all
scheduled maintenance was performed in a
t imely manner.
Engine oil consumption
The 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
cooling of interna l engine components, all in­
ternal combust ion engines consume a certain
amount of oil. Oil consumpt ion varies from
engine to engine and may change sign ificantly
over the life of the engine. Typically , engines
with a spec ified break- in period (see
¢ page 201) consume more oil during the
break -in pe riod t han they consume afte r o il
consumption has stabilized.
Under normal cond it ions, the rate of oil con­
sumption depends on the q ua lity and viscos ity
of the oil , the RPM (revol utio ns per minute) at
which the engine is opera ted, the ambient
temperature and road conditions . Furt her fac­
tors are the amount of oil dilution from water
condensation or fue l residue and the oxida ­
tion level of the oil. As any engine is subject to
wear as m ileage builds up, the oil consump­
t ion may increase over time until replacement
of worn components may become necessary .
With a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be es­
tablished or spec ified . There is no alternative
to regular and frequent checking of the o il lev­
el, see
Not e.
If the yellow engine oil level warning symbol
in the instrument clus ter
II lights up, you
shou ld check the oil leve l as soon as possib le

- Observe and follow lega l regulations
when disposing of empty oil containers.
Changing the engine oil
We recommend that have your oil changed by
an authorized Audi dealer or a qualified serv­
ice station.
Before you check anything in the engine com­
partment,
al ways read and h eed all WARN ­
INGS c::> &. in Working in the engine compart­
ment on page 224.
The engine oil must be changed according to
the intervals spec ified in your Warranty
&
Maintenance book let . This is very important
because the lubricating prope rties of oil di­
minish gradua lly dur ing normal veh icle use.
Under some c ircumstances the eng ine o il
should be changed more frequently . Change
oil more often if you drive most ly short dis­
tances , operate the vehicle in dusty areas or
under predominantly stop-and-go traffic con­
ditions, or have your vehicle where tempera -tu res remain below freezing for extended pe­
riods.
Detergent additives in the oil will make fresh
o il look dar k after the engine 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 required, we strongly recommend that
you have your oil changed by an authorized
Aud i deale r or a qualified service station.
If you choo se to chan ge your o il yours elf ,
please note the fo llowing important informa ­

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-
gine 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 run­
