Engine oil
Engine oil specifications
The engine in your Audi needs the right kind
of oil.
T he eng ine in your Audi is a sophisticated
powerplant that was built to exacting specifi
cations. This eng ine needs the right k ind of
engine oil that meets specifications regarding
quality and viscosity so that it can r un
smooth ly and reliably. Choosing the right o il
and changi ng oil within the t ime and mileage
in tervals p rin ted in you r vehicle's Wa rranty
&
Maintenance booklet matters a lot more to
day than it did years ago . Audi has deve lope d
a specia l quality sta ndard for engine oil t hat
will help assure that your vehicle's engine w ill
get the lubrication it needs for proper opera
tion.
216 Check ing and filling
Modern engine lubrication has taken a quan
tum leap in the last few years. Many synthetic
oils ava ilable 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 to he lp keep your vehicle's engine
running smoothly and help prevent the for
mat ion of harmfu l deposits, sometimes called
"s ludge ," that ove r time can lead to expensive
repairs .
At the time of pr int ing , engine o ils available in
the U .S . and Canada that meet the exacting
specifi cations of A udi oi l standard VW 502 00
a re synthetic engine oils. This does not mean,
however, that every syn thetic engine oi l wi ll
meet Audi oil standard VW 502 00. So always
be sure that you use an approved oil.
To help prevent the format ion of harmful de
posi ts use only oi l with the fo llow ing specifi
cations printed on the oil container :
Audi oil standard VW 502 00
O il container labe ls may carry the specif ica
tion s ingly or in comb inat ion with other des ig
nations and oil qua lity standards .
Viscosity
Engine oi ls are graded according to their vis
cosity. The proper viscosity grade oil for your
engine depends on cl imactic or seasonal con
d itions where you drive. You can use oil with a
viscosity grade of SA E SW40 across all tem
pe ratu re ranges for normal driving conditions .
However, if eng ine o il viscos ity grade
SAE SW40 is no t ava ilable, you can a lso use
viscosity grade SAE SW-30 or SAE OW -40 as
long as it meets Audi o il quality standard
VW 502 00 specifications .
Because engine oil that meets the Audi oil
standard may not be available everywhere
when you need it, we strongly recommend
that you always carry with you an ext ra quart (
li te r) of oil that exp ress ly con forms to the
VW 502 00 spec ification, in case you have to
top
off the oil while on the road.
Only if the level of the o il is a t or be low the
min imum mark on the o il dipstick - and no oi l
that expressly conforms to Aud i oi l standard
VW 502 00 spec ificat ions is ava ilable -may
you top
off with a high quality engine oi l, pref
erably syn thet ic-based, that meets ACEA A3
or AP I SM spec ificat ions, but even then, only
in v iscosity grades SAE SW-40, SAE SW-30, o r
SAE OW- 40. However, during the ent ire time
be twee n oil change intervals, never top
off
with more than a total of 0.5 q t/lite r engine
o il that does no t conform to Audi o il specifica
tion VW 502 00.
For more informa tion about eng ine oi l tha t
has been approved for your veh icle, ple ase
contac t either yo ur authorized Aud i deale r or
Audi C ustome r Re lations at 1 (800) 82 2-2834
or visit o ur web site at www .audiusa.com or
www.aud icanada .ca. Here you w ill also find a
current list of oils (manufacturers, brand
names e tc.) tha t conform to Audi oil s tanda rd
vw 502 00 .
Changing the engine oil
The eng ine oi l and oil fi lter m ust be changed
according to the mileage (kilometers) and
time intervals specified in your ve hicle's War
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil ca n reduce eng ine performance and
can lead to expensive engine repa irs .
Changi ng the oil at the recommended inter
vals is so very important because the lubricat ing proper ties of oil decrease gradually during
norma l veh icle use . If you are not sure when
you have your oil changed, ask your author ized Audi Serv ice Adv isor.
Under some circumstances the engine oil
shou ld even be cha nged more frequent ly .
Change oil more often if you drive mostly
sho rt distances, operate the ve hicle in dusty
areas o r most ly unde r stop-and-go t raff ic con-
di tions, o r when you use your vehi cle where .,..
temperatures stay below freezing point for l ong periods.
Detergent add itives in the o il w il l make fresh
oil look dark after the eng ine has been run
ning fo r a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
D am ag e or m alfun ction s due to lack of
ma intenanc e
It is essential that you change your oil at the
r ecommended inte rva ls using only engine o il
t hat complies wi th A udi oi l standard
VW 502 00 . Your Limited New Vehicle War
ranty does not cover damage or malfunctions
d ue to fa ilure to fo llow recommended mainte
nance and use requ irements as set forth in
the Audi Owner's Manua l and Warranty
&
Maintenance book let . Your dea ler will have to
deny warranty coverage u nless you present to
the dea ler p roof in the fo rm of Serv ice or Re
pa ir Orde rs that all s chedu led maintenance
wa s pe rformed in a t imely manner .
Engine oil consumption
The engine in your vehicle dep ends on an ade
quate amount of oil to lubricate and cool all
of its moving parts.
In o rder to provide effective lubrication and
cool ing of i nternal engine components, a ll in
ternal comb ustion eng ines consume a cert ain
amo unt of o il. Oil cons umption varies from
engine to engine and may change significantly
over the life of the engine. Typ ica lly, engines
with a specified break-in per iod (see
¢
page 198) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under norma l conditions, the rate of oil con
sumpt ion depends on the quality and viscosity
of the oil, the RPM (revo lutions per m inute) at
which the engine is operated, the amb ient
temperature and road condit ions. Furthe r fac
tors ar e the amount of o il d ilution from wate r
condensation or fuel residue and the ox ida
tion level of the oi l. As any engine is s ubje ct to
Checkin g and fillin g 217
wear as m ileage builds up, the oil consump
tion may increase over time until replacement
of worn components may become necessary.
Wi th a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be es
tablished or specified. There is no alternative
to regular and frequent check ing of the o il lev
el, see
Note .
If the yellow engine oil leve l warning symbo l
in the instrument cluster
II li ghts up, you
sho uld check the oil leve l as soon as possib le

convenience

(D Tips
- The oil pressure warning display. is
not an indicator of the oil le vel. Do not
rely on it . Instead, check the oil level in
your engine at regu lar intervals, pref
erably ea ch time you refuel, and always
before going on a long trip .
-If you have the impression yo ur engi ne

properly diagnosed . Keep in mind that
the accurate meas urement of o il con
sumption requires great care and may
take some t ime. Y our Audi dea ler has in
