Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil.
The engine in your Audi is a sophisticated
powerplant that was built to exacting specifi
cations. This engine needs the right kind of
engine o il that meets spec ificat ions regarding
qua lity and viscos ity so that it can run
smoothly and reliably . Choos ing the righ t oi l
and changing oil w ith in the time a nd mileage
interva ls printed in your vehicle's Warranty
&
Maintenance book let matters a lot more to
day than it did yea rs ago. A udi has developed
a special quality standard for engine oil that
will help assure that your veh icle's eng ine will
get the lubrication it needs for proper opera
tion .
Modern engine lubrication has taken a quan
tum leap in the last few years. Many synthetic
oils ava ilable today provide better engine lu
b rication that can outlast traditiona l petrole
um-based o ils, making them a smart choice
for use throughout the life of you r A udi .
Whether you use synthetic or petroleum based engine oil, the oil that you use must
conform to Audi's oil qual ity standard
VW 502 00 to help keep your veh icle 's eng ine
r unning smoo thly and help prevent t he fo r
ma tion of harmfu l deposi ts, some times called
"s ludge," that over t ime can lead to expensive
repairs.
A t the time of pr intin g, engine o ils availab le in
the U .S . and Canad a that meet the exact ing
specifications o f A udi oil standard VW 502 00
are synthetic engine oils . This does not mean,
however, that eve ry synthetic engine oil wi ll
meet A udi oil standard VW 502 00. So a lways
be sure that you use an approved o il.
To help preve nt the formation of harmful de
posits use only oi l with the fo llow ing spec ifi
cations printed on the oil container :
Audi oil standard VW 502 00
Oil container labels may car ry the specifica
tion sing ly or in combination with othe r desig
nations and oil quality standa rds .
Viscosity
Engine o ils are graded accord ing to their vis
cosity . Th e pr oper viscos ity grade oil fo r you r
engine de pends on clim actic o r seaso nal con
di tions where yo u drive. You can use o il wit h a
viscosity grade o f SAE SW40 across all tem
perature ranges for norma l driving conditions.
However, if engine oil visco sity g rade SA E
SW40 is not ava ilable, you can a lso use v iscos
ity grade SA E SW -30 or SA E OW -40 as long as
it meets Audi oil q ua lity standard VW 502 00
specificat ions.
Beca use engine o il that mee ts the Audi o il
standard may not be availab le everywhere
when you need it, we strong ly recommend
t h at you a lways carry with you an extra quart
( li ter) of oil that express ly 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 be low the
min imum ma rk on the o il dipstick - and n o oi l
that expressly conforms to Audi o il standard
VW 502 00 specifications is availab le -may
yo u top off with a high quali ty engine o il, p ref
erably synthet ic-based, that me ets ACEA A3,
AC EA AS o r AC EA B S or A PI SL spec ifi cat io ns,
but even t hen, only in v iscosi ty g rades SA E
SW -40, SA E SW-3 0, or SAE OW-40 . However,
during the entire time between oi l change in
te rva ls , never top
off with more than a tota l
of 0 .5 qt/liter engine oil that does not con
form to Audi oil specification VW 502 00.

Audi C ustomer Re lations at 1 (800) 822-2834
or v is it our web site at www.audiusa.com or
www .aud icanada .ca. Here you w ill also find a
c ur rent l ist of oils (manufacturers, bra nd
names etc.) that conform to Aud i oil standa rd
vw 50 2 00.
Changing the engine oil
The engine oil and oil filter must be changed
according to the mi leage (kilometers) and
time interva ls specified 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 o il 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 oi l changed, ask your author
i zed A udi Service Advisor.
Under some circumstances the engine o il
should even be changed more frequently.
Change o il more often if you drive mostly
short distances, ope ra te the vehicle in dusty
areas or mostly under s top-and-go traffic con
d itions, or when yo u use your vehicle whe re
temperatures stay below freezing point for
l ong periods.
D etergen t additives i n the o il w il l make fresh
oil look dark after the eng ine has been run
ning for a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
Damage or malfunction s due t o lack of
m aintenance
It is essen tial that you change your oil at the
r ecommended inte rva ls using only engine o il
that complies with A udi oil standard
VW 502 00. Yo ur Limited New Vehicle War
ranty does not cover damage or malfunctions

Engine oil consumption
The engine in your vehicle depends on an ade
quate amount of oil to lubricate and cool all
of its moving parts .
In order to provide effective lubrication and
cooling of interna l eng ine components, all in
te rnal combust io n engines consume a certain
amount of oil. Oil consumpt io n va ries from
engine to e ngine and may change sig nifican tly
ove r the life of the engine. Typically, engines
with a spec ified break -in pe riod (see
c::> page 158) consume more oil d uri ng the
break-in pe riod than they consume afte r oi l
consumption has stabilized.
U nder normal cond itions, the rate of oi l con
s u mption depends on t he q uality and viscos ity
of the oil, the RP M (revolut ions 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
condensa tion or fue l residue a nd the oxida
tion level of the oil. As any eng ine is subject to
wear as m ileage builds up, t he oil co nsump
t ion may increase over time until repla cement
of wo rn components may be come necessary.
Wi th a ll these va riab les coming into p lay, no
standard rate of oil consumpt io n can be es
t a bl is h ed o r spec ified . There is no alte rnative
to regular and frequent chec king of the o il lev

Engine cooling system
Coolant
The coolant provides cooling for the engine.
The percentage of the coolant additive deter
mines the freeze protection of the coolant in the winter.
The cooling system has been filled at the fac
tory with a permanent coo lant which does not
need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly
col-based coolant additive Gl2++ ant ifreeze
with ant icor rosion add itives (SO% fo r USA
models; 60% for Canad ian models).
Checkin g and fillin g 181
Coolant additive
The percentage of the coo lant add itive de
pends on the climatic cond itions in wh ich the
vehicle is operated . If the percentage of
freeze protection i n the coo lant is too low, the
coolant can freeze, leading to a failure o f the
cooling and heating circuit.
T he percentage of coolant addit ive has al
ready been adjusted at the factory for the ve
hicle's climatic conditions.
T he m ix rat io for USA models is SO% wa ter
and SO% coolant addit ive, for Canadia n mod
els 40% water and 60% coolant additive. This
mixture both ass ures the necessary frost pro
tection (-31 °F/-3S °C for USA models, -40 °F/-40 °C for Canada models) a nd protects
metal components i n the engine's cooling sys
tem from corrosion and scaling. It also ra ises
t h e boili ng poi nt of the coo la nt.
Summer time
Do not reduce the concentrat ion of the cool
ant in the summer by adding p la in water.
The
proportion of coolant additive must be at
least 50 % but not more than 60 %
to main
ta in an tifreeze pro te cti on and cooling eff ic ien

- To avoid being bu rned, do not spill an
tifreeze or coolant on the ex haust sys
tem or hot engine pa rts. Under certain
cond itions, the ethylene glycol in en
gine coolant can catch fire .
- Antifreeze is poisonous . Always store an
tifreeze in its origina l container and well
out of the reach of children .
- If you dra in the coo lant, it m ust be
caught and safely stored in a proper con
taine r clearly marked " poison" .
CD Note
- Coolant pollutes the environment and
