Engine oil
Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil.
T he eng ine in your Aud i is a soph ist icated
powerplant that was built to exact ing spec ifi­
cat ions . T his engine needs the right kind of
engine oil that meets specifications regard ing
quality and viscosity so that it can run
smooth ly and reliably . Choosing the right o il
and changing oil within the time and mileage
i ntervals printed in your vehicle's Warranty
&
Maintenance booklet matters a lot more to­
day tha n it did years ago. Audi has developed
a spec ia l quality standard for engine oil that
will help assure that you r vehicle's engine w ill
get the lubr ication it needs fo r proper opera­
t ion.
Modern engine l ubr ication has taken a q uan­
tum leap in the last few years. Many synthet ic
1J.

184 Checking and filling
Detergent additives in the o il 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 oil more often than recommended.
D am ag e o r m alfun ction s due to lack of
m ainten ance
It is essent ial that yo u change your oil at the
recommended intervals using only engine oil
that complies with Audi oi l 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 irements as set forth in
the Audi Owner's Manual and Warranty
&
M aintenance book let . Your dea ler will have to
deny warranty coverage un less you p resen t to
the dea ler proof in the form of Servi ce or Re­
pa ir Orde rs that all schedu led 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 lubr ication and
cooling of internal engine components, a ll in­
ternal comb ustion engines consume a certain
amount of oil. Oi l consumption varies from
engine to engine and may change significantly
over the life of the eng ine . Typically, eng ines
with a specif ied break-in per iod (see
c::;, page 159) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
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 operated, the ambient
temperature and road cond it io ns. Furthe r fac­
tors are the amo unt 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 subject to
wear as mileage bui lds up, the oil consump­
tion may increase over t ime until replacement
of worn components may become necessary. Wi
th 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 instr ument cluster
II lights up, you
sho uld check the oil leve l as soon as possib le
with the oil dipstick c::;, page 185. Top off the
o il at your earliest conven ience
c::;, page 185 .
A WARNING
-Before you chec k anything in the eng ine
compartment, a lways read and heed a ll
WAR NINGS
c::;, .& in Working in the engine
comportment on page 180.
CI) Note
D riving with an insufficient o il level is like­
l y to cause sever e damage to the engine.
(D Tips
- The oil pressure warn ing display. is
not an indicator of the oil level. Do not
re ly on it . Instead, check the oil level in
your engine at regular intervals, pr ef­
erably ea ch time you refu el, and alway s
before going on a long trip.
- If you have the impression yo ur engine
cons umes excessive amoun ts of oil, we
recommend that you consult your Aud i
dealer to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate meas urement of o il con­
sumption requ ires great care and may
take some t ime . Your Audi dea ler has in­
struct ions about how to measure oil con­
sumption acc urately.

Contact an authorized Audi dealer to
draw off oil, if necessary.
- Audi does not recommend the use of oil
additives. They may damage the engine
and adversely affect your New Vehicle
Warranty.
@ For the sake of the environment
- Under no circumstances can the oil come
in contact with the sewage network or
the soil.
- Observe and follow legal regulations
when disposing of empty oil containers.
Changing the engine oil
We recommend that have your oil changed by
an authori zed Audi dealer or a qualified serv­
ice station .
Before you check anything in the engine com­
partment,
always read and heed all WARN·
INGS
¢ & in Working in the engine compart­
ment on page 180 .
The engine oil must be changed according to
the intervals specified in your Warranty &
Maintenance booklet. This is very important
because the lubricating properties of oil di ­
minish gradually during normal vehicle use .
Under some circumstances the engine oil
should be changed more frequently . Change
oil more often if you drive mostly short dis­
tances , operate the vehicle in dusty areas or
under predominantly stop-and-go traffic con­
ditions, or have your vehicle where tempera­
tures remain below freezing for extended pe­ riods. Detergent
additives in the oil will make fresh
oil look dark after the engine has been run­
ning for a short 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 special tools and necessary ex­
pertise required, we strongly recommend that
you have your oil changed by an authorized
Audi dealer or a qualified service station .
If you choose to change your oil yourself,
please note the following important informa­
tion:
A WARNING
=
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot en-
gine oil, let the engine cool down to the
touch.
- When removing the oil drain plug with
your fingers, stay as far away as possible. Always keep your forearm parallel to the
ground to help prevent hot oil from run­
ning down your arm.
- Drain the oil into a container designed
for this purpose, one large enough to
hold at least the total amount of oil in
your engine.
- Engine oil is poisonous. Keep it well out
of the reach of children.
- Continuous contact with used engine oil
is harmful to your skin. Always protect
your skin by washing oil off thoroughly
with soap and water.
(D Note
Never mix oil additives with your engine
oil. These additives can damage your en­
gine and adversely affect your Audi Limit­
ed New Vehicle Warranty.

@ For the sake of the environment
- Before changing your oil, first make sure
you know where you can properly dispose of the used oil.
- 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 drains.
- Recycle used engine oil by taking it to a
used engine oil 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
qu ires little at tention.
The cooling system has been filled at the fac ­
tory with a permanent coolant which does not n eed to be changed. The coolant consists of a
mixture of wa ter and the man ufacturer's g ly ­
col-based coolan t addi tive Gl3 ant ifree ze
with ant icorrosion add itives (50% for USA
models; 60% for Canadian models) . This mix­
ture both assures the necessary frost protec ­
tion and protects metal components in the
engine's cooling system from corrosion and
scaling. It also raises the boiling po int of the
coolant.
Do not reduce the concentration of the coo l­
ant in the summer by adding plain water.
The
proportion of coolant add itive must be at
lea st 50°/4 but not more than 60°/4
to ma in­
tain antifreeze protection and cooling efficien­ cy. If the coolant frost pro tect io n is too low,
the coolant cou ld freeze and dam age the veh i­
cle heating and eng ine cooling system.
For year-round driving, antifreeze is added at
the facto ry for temperatures down to:
- -31°F( -35°C)USA
- -40 °F ( -40 °C) Canada.

(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your v ehicle is sufficient to meet the cli­
mate conditions. This is especia lly impo r­
t an t if you live in a region where t he win­
t er is ex treme ly cold. If ne cessary, in­

for your veh icle. This coolant additive is
ava ilable at autho rized Aud i dea le rs.
Othe r types of antifree ze can sig nifi­
cantly reduce cor ros io n protec tion. The
res ulting co rrosion can cause a loss of
coolant an d serio us en gine damage.
- Do not add any type of rad iator le ak seal­
