Engine oil
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 oil that meets specifications regarding
quality and viscosity so that it can run
smoothly and reliably . Choosing the right oil
and changing oil within the time and mileage
intervals printed in you r vehicle's Warranty
&
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 help assure that your vehicle's engine wi ll
get the lubrication it needs for proper opera-
tion. ..,.
Page 235 of 310

Modern eng ine lubrication has taken a quan
tum leap in the last few years . Many synt hetic
oils ava ilable today provide better engine lu
brication that can outlast traditional petrole
um-based o ils, 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
mat ion of harmfu l deposits, sometimes called
"s ludge," that ove r time can lead to expensive
r epairs .
At the t ime of pri nting, engine o ils available in
the U .S . and Canada that meet the exacting
specifications of Audi oi l standard VW 502 00
are synthetic engine oils. This does not mean, h owever, that every synthetic engine oil w ill
meet Audi oil standard VW 502 00. So always
be sure that you use an approved oi l.
To help preve nt the format ion of harmful de
posits use only oi l with the fo llowing spec ifi
cations printed on the oil container:
Audi oil standard VW 502 00
O il conta iner labels may carry the specif ica
tion s ingly or in comb inat ion w ith other des ig
nations and oil qua lity standards .
Viscosity
Engine oi ls are graded according to their vis
cosity. The proper v iscosity grade oi l for your
engine depends on cl imactic or seasonal con
d itions where you dr ive. You can use oil with a
viscosity grade of SAE SW40 across all tem
pe rature ranges for normal d riving conditions .
However, if eng ine oi l viscosity grade
SAE SW40 is not 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 st rongly recomme nd
that you always carry with you a n ext ra quart
Checkin g and fillin g 233
(li ter) of oil that exp ress ly con forms to the
VW 502 00 specificatio n, in case you have to
top
off the o il while on the road.
Only if the level of the o il is at or be low the
minimum mark -and no oi l that expressly
confo rms to Audi oil standard VW 502 00
spec ifications is available -may you top
off
with a h igh quality engine o il, preferab ly syn
thet ic-based, that meets ACEA A3 or API SM
spec ifications, but even then, only in v iscosity
grades SAE SW-40, SA E SW-30, or
SA E OW-40 . However, during the ent ire time
betwee n oil change in tervals, never top
off
wi th more than a total of 0.5 q t/ li ter engine

Changing the engine oil
T he eng ine oi l and o il f ilter m ust be changed
according to the mileage (kilometers) and
time intervals specified i n your ve hicle's War
ranty
& Maintenance booklet. Do not exceed
these interva ls - harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive engine repairs.
Changi ng the oil at the recommended inter
vals is so very important beca use the lubricat
ing propert ies of oil decrease gradually during
norma l veh icle use . If you a re not sure when
yo u have your o il cha nged, ask your author
i zed Audi Se rv ice Adv isor.
Under some circumstances the engine oil
shou ld eve n be changed more frequent ly.
Change oil more often if you dr ive most ly
sho rt distances, operate the ve hicle in dusty
areas o r most ly under stop-and -go traff ic con-

temperatures stay below freezing point for long periods.
Detergent additives in the oil 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 malfun ctions due to lack of
maintenance
It is essential that you change your oil at the
recommended intervals using only engine o il
that complies with Audi oi l standard
VW 502 00. Your Limited New Vehicle War
ranty does not cover damage or malfunctions
due to fail ure to fo llow recommended mainte
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty &
Maintenance booklet . Your dealer will have to
deny warranty coverage unless you present to
the dea ler proof in the form of Service or Re
pa ir Orders that all scheduled ma intenance
was performed in a timely manner.
Eng ine 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
cool ing of internal engine components, all in
ternal combustion eng ines consume a certain
amount of oil. Oil consumption varies from
engine to engine and may change significantly
over the life of the engine. Typically, engines
with a specif ied break-in period (see
¢ page 204) consume more oil during the
break-in period than they consume after oil
consumption has stabilized.
Under norma l conditions, the rate of oil con
sumption depends on the quality and viscosity
of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road condit ions . Further fac
tors are the amount of oil d ilution from water
condensat ion or fuel residue and the oxida
tion level of the oil. As any engine is subject to wear as mi
leage builds up, the oil consump
tion may increase over time until replacement
of worn components may become necessary.
With all these variables coming into play, no
standard rate of oil consumption can be es
tablished or specified. There is no alternative
to regu lar and frequent checking of the o il lev
el, see Note.
If the yellow engine oil leve l warning symbo l
in the instrument cluster
II lights up, you
sho uld check the oil leve l as soon as possible
c:> page 235. Top off the oil at your earliest
convenience
c:> page 235.
A WARNING '"---
Before you check anythi ng in the engine
compartment, always read and heed all
WARNINGS
c:> A in Working in the engine
compartment on page 230.
(D Note
Driving with an insufficient o il level is like
ly to cause severe damage to the engine.
(D Tips
- The oil pressure warning display . is
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 th e impression your engine
consumes excessive amounts of oil, we
recommend that you consult your Audi
dealer to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate meas urement of oil con
sumption requ ires great care and may
take some t ime. Your Audi dealer has in
structions about how to measure oil con
sumption accurately.

Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro
te cts the engine from freezing in the winter .
The cooling system is sealed and generally re
qu ires little attention .
The cooling system has been filled at the fac
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly
col-based coolant additive G13 ant ifreeze
w ith anticorrosion add itives (50% fo r USA
models; 60% for Canad ian models). This mix
ture bot h assu res the ne cessary frost protec
tion and protects metal components in the
engine's coo ling system from corrosion and
scaling. It also raises the boili ng po int of t he
coolant.
D o not red uce the concentration o f the coo l
ant in the summer by adding plain water .
The
proportion of coolant addit ive must be at
least 50% but not mo re than 60 %
to main
tain antifree ze protection and cooling efficien
cy. If the coolant frost protection is too low,
the coolant cou ld freeze and damage the veh i
cle heating and eng ine cooling system .
For year-round driving, antifree ze is added at
the factory for temperatures down to:
- -3 1°F (-35°C)USA
- -40 ° F ( - 4 0 °C) Canada.

The location of the coolant expansion tank
can be seen in the engine compartment illus
tration
¢ page 232.
To obtain an accurate reading, the engine
must be switched off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning light in the Auto-Check System¢
page 16 will
illuminate until you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level sensor , we
still recommend you check the coolant level
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cool
ing system should be inspected immediately
by your authorized Audi dealer.
It is not
enough merely to add coolant.
In a
sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
_& WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald
ing from hot coolant by following these
steps. -
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise direction while ap
plying light, downward pressure on the
top of the cap .
- To avoid being burned, do not spill anti freeze or coolant on the exhaust system
or hot engine parts. Under certain condi
tions, the ethylene glycol in engine cool
ant can catch fire .
(D Note
Do not add any type of radiator leak seal
ant to your vehicle's engine coolant. Add
ing radiator repair fluid may adversely af
fect the function and performance of your
cooling system and could result in damage not covered by your New Vehicle Limited
Warranty .
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine com
partment,
always read and heed all WARN
INGS ¢&. in Working in the engine compart

Replacement engine coolant must conform to
exact specifications ¢
page 23 7, Coolant. We
recommend using only coolant additive G12+
+, G13 or in an emergency G12+. Do
not use a
different additive. In an emergency use plain
water until you can get the correct additive
and can restore the correct ratio. This should
be done as soon as possible .
If you have lost a considerable amount of
coolant , then you should add cold antifreeze
and cold water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex
cess coolant will be forced out through the
