Engine oil
Engine oil specifications
The engine in your Audi needs the right kind
of oil.
The eng ine in your Aud i is a sophist icated
powerplant that was built to exacti ng spec ifi­
cations . T his eng ine needs t he right k ind of
engine oil that meets specifications regarding
quality and viscosity so that it can run
smoot hly and reliably . Choosing the right o il
and changing oil within the time and mileage
intervals printed in your vehicle's Warranty
&
Maintenance booklet matters a lot more to­
day than it did years ago. Audi has developed
a specia l quality standard for engine oil t hat
will help assu re that you r vehicle's engine w ill
get the l ubr ication i t needs fo r proper opera­
tion.
Modern engine lubr ication has taken a q uan­
tum leap in the last few years. Many synt het ic

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 to help keep your vehicle's engine
running smoothly and help prevent the for­
mation of harmful deposits, sometimes called
"sludge," that over t ime can lead to expensive
repairs .
At the time of printing, engine oils available in
the U .S . and Canada that meet the exacting
specifications of Audi oil standard VW 502 00
are synthetic engine oils. This does not mean, however, that every synthetic engine oil will
meet Audi oil standard VW 502 00. So always
be sure that you use an approved oil.
To help prevent the formation of harmful de­ posits use only oil with the following specifi­
cations printed on the oil container:
Audi oil standard VW 502 00
Oil container labels may carry the specifica­
tion singly or in combination with other desig­
nations and oil quality standards .
Viscosity
Engine oils are graded according to their vis­
cosity. The proper viscosity grade oil for your
engine depends on climactic or seasonal con­
ditions where you drive. You can use oil with a
viscosity grade of SAE 5W40 across all tem­
perature ranges for normal driving conditions.
However, if engine oil viscosity grade SAE
5W40 is not available, you can also use viscos­
ity grade SAE 5W-30 or SAE OW-40 as long as
it meets Audi oil 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 extra quart (liter) of oil that expressly conforms to the VW 502 00 specification, in case you have to
top
off the oil while on the road.
Only if the level of the oil is at or below the
minimum mark on the oil dipstick - and no oi l
that expressly conforms to Audi oil standard
VW 502 00 specifications is available -may
you top
off with a high quality engine oil, pref­
erably synthetic-based, that meets ACEA A3
or API SM specifications, but even then, only
in viscosity grades SAE SW-40, SAE 5W-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
oil that does not conform to Audi oil specifica­
tion VW 502 00.
For more information about engine oil that
has been approved for your vehicle, please
contact either your authorized Audi dealer o r
Audi Customer Relations at 1 (800) 822-2834
or visit our web site at www.audiusa.com or
www.audicanada.ca . Here you will also find a
current list of oils (manufacturers, brand
names etc.) that conform to Audi oil standard
vw 502 00.
Changing the engine oil
The engine oil and oil filter must be changed
according to the mileage (kilometers) and
time intervals specified in your vehicle's War­
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive engine repairs.
Changing the oil at the recommended inter­
vals is so very important because the lubricat­
ing properties of oil decrease gradually during
normal 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 oil
should even be changed more frequently. Change oil more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
ditions, or when you use your vehicle where
temperatures stay below freezing point for
long periods.

Detergent additives in the oil will make fresh
oil look dark after the engine has been run­
n ing for a short time . This is norma l and is not
a reason to change the o il more often than
recommended.
D amage o r m alfu nctions due to lac k of
m ainten ance
It is essen tial that yo u change your oil at the
recommended inte rva ls using only engine oil
that complies with A udi oil standard
VW 502 00 . Your Lim ited New Vehicle War­
ranty does not cover damage or malfunctions
due to failure to follow recommended mainte­ nance and use requ ireme nts as set forth in
the Audi Owner 's Manual and Warranty
&
Maintenance book let . Your dea ler will have to
deny warranty coverage u nless you p resent to
the dea ler proof in the form of Serv ice or Re­
pa ir Orde rs that all scheduled maintenance
was performed in a timely manner.
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving ports.
I n o rder to prov ide effective l ubr ication and
cooling of internal engine components, a ll in­
ternal comb ustion engines consume a certain
amo unt of oi l. Oi l cons umption varies from
engine to engine and may change significantly
over the life of the eng ine . Typ ically, eng ines
with a specified break-in per iod (see
¢ page 150) consume more o il during the
break-in per iod than they consume after oil
consumption has stab ilized .
Under normal conditions, the rate of oil con­
sumpt io n depends on the quality and viscosity
of the oil, the RPM (revolutions per m inute) at
which the engine is ope rated, the ambient
temperature and road condi tions. Furt her fac­
tors are the amo unt of oil d ilution from wate r
condensation or fuel residue and the oxida­
tion level of the oi l. As any engine is subject to
wear as mileage bui lds up, the oil consump ­
tion may increase over time until rep lacement
of worn components may become necessary.
Checkin g and fillin g 169
With a ll these variab les coming into p lay, no
standard rate of oil consumption can be es ­
tab lished or spec ified . There is no alte rnative
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
Ill li ghts up, you
sho uld check the oil leve l as soon as possib le
with the oil dipstick¢ page 170. Top off the
o il at your earliest convenience ¢
page 170 .
A WARNING
Before you check anything i n the engine
compartment, always read and heed a ll
WAR NINGS ¢

compor tment on page 165.
(D Note
D riving w it h an insufficient o il level is like­
l y to cause severe damage to the engine.
© Tips
- The oil pr essur e warn ing display. is
not an indicator of th e oil level. Do not
rely on it . Instead, che ck the oil level in
your engine at regu lar int ervals, pr ef­
erably e ach time you r efuel, and always
before going on a long trip .
-If you have the impression yo ur engi ne

recommend that you consu lt your Aud i
dea ler to have the cause of your concern
properly d iagnosed. Keep in mind that
the accurate meas urement of o il con­
sumption requires great care and may
take some t ime . Your Audi dea ler has in­
st ruct ions about how to measure oil con­
sumption acc urately.

172 Checking and filling
@ For the sake of the environment
- Before changing your oil , first make sure
you know where you can properly dispose
of the used o il.
- Always dispose of used engine oil proper­
l y. Do not dump it on garden soi l, wood­
ed areas, into open streams or down
sewage dra ins.
- Recycle used engine oil by taking it to a
used engine o il collection facility in your
area, or contact a service station .
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­ tects the engine from freezing in the winter.
The cooling system is sea led and generally re­
q uir es little attention .
The cooling system has been filled at the fac ­
tory with a pe rmanent coolant which does not
need to be c hanged. The coolant consists of a
mixture of spec ia lly condi tioned water and the
manuf acturer 's glyco l-b asedcoolan t addi -
tive G l3 antifreeze with ant icorros ion addi ­
tives (50% for USA models ; 60% for Canadian
mod els). This mixture both assures the nec es­
sary frost protection and p rotects metal com ­
ponents in the engine's cooling system from
corrosion and scaling . It a lso raises the boil­
ing point of the coo lant .
Do not red uce the concentration o f the coo l­
ant in the summer by adding plain water.
The
proportion of coolant add itive must be at
l e a st 50 % but not more than 60 %
to main­
tain antifreez e protection and cooling efficien­
cy . If the coolant frost prote ct ion is too low,
the coo lant cou ld free ze and damage the veh i­
cle hea ting and eng ine cooling system.
For yea r-round d riving, antifreeze is added at
the fac to ry for temperatures down to:
-- 31°F( -35°C)USA
- -40 °F ( -40 °C) Canada. If
you must add coolant, use a mixture o f wa ­
ter and coolant additive . Mixing the coo lant
additive with distilled water is recommended.
A WARNING

(D Note
- Before winter sets in, have the coo lant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­ m ate conditions . This is especia lly impor­
tan t if you live in a reg io n wher e the win ­
