The engine oil us ed in your Audi needs the right kind of
oil.
The engine in your Audi is a sophisticated powerplant that was built
to exacting specifications. This engine needs the right kind of engine oil that meets specifications regarding quality and viscosity
so that it can run smoothly and re liably. Choosing the righ t oil and
changing oil within the time and mileage interva ls printed in your
vehicle's Warranty
& Ma intenance book let matters a lo t more today
than it did years ago. Audi has developed a special quality standard
for engine oil that wil l help assure that your vehicle's engine wi ll get
the lubrication it needs for proper operation .
Mode rn engine lubrication has taken a quantum leap in the last few
years . Many syn thetic oils available today provide better engine
lubrication that can outlast traditional petroleum-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 oi l
that you use must conform to Audi's oi l qua lity standard VW 502 00

to help keep your vehicle's engine running smoothly and help
prevent the formation of harmfu l deposits, sometimes called
"sludge, " that over time can lead to expensive repairs .
At the time of printing, engine oils available in the U.S. and Canada
that meet the exacting specificat ions of Audi oil standard VW 502 00
are synthetic engine oils. This does not mean, however, that every
synthetic engine oil will meet Audi oi l standard VW 502 00. So
a lways b e sur e that you use an approved oil.
To help prevent the formation of harmful deposits use only oi l with
the following specifications printed on the oil container :
Audi oil sta nda rd VW 502 00
Oil container labels may carry the specification singly or in combi
nation with other designations and oil quality standards.
V iscosi ty
Engine oi ls are graded according to their viscosity . The proper
viscosi ty grade oi l for your engin e depends on climactic or seasonal
conditions where you drive . You can use o il with a v iscosity grade of
SAE 5W40 across all temperature ranges for normal driving condi
tions.
However , if eng ine oil viscosity grade SAE 5W40 is not available, you
can a lso use viscosity grade SAE 5W -30 or SAE 0W -40 as long as it
meets Audi oil quality standard VW 502 00 specifications.
B ecause engin e oil that meets the Audi oi l standard may not be
avai lable everywhere when you need it, we strongly recommend
that you a lways carry with you an extra quart !liter) of oil that
express ly conforms to t he VW 502 00 specification, in case you have
to top off the oil while on the road.
Only if th e level of the oil is at or be low the minimum mark on the
oi l dipstick -and no oil that express ly conforms to Audi oi l standard
VW 502 00 specifications is avai lable -may you top off with a high
quality engine oi l, preferably synthetic -based, that meets ACEA A3,
ACEA A5 or ACEA B5, API SL or ILSAC GF -3 specifications , but even
t hen, only in viscosity grades SAE 5W -40, SAE 5W -30, or SAE 0W -40.
However, during the entire time betwe en oil change int erva ls, nev er 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 vehic le, please contact either your authorized Audi dealer or
Aud i Customer Relat ions at 1 (800) 822-2834 or v isit our web s ite at
www.audiusa.com or www.audicanada.ca. Here you will also find a
current list of o ils (manufacturers, brand names
etc.I that conform
to Audi oi l standard VW 502 00.
Ch an g in g t he en gin e oil
The engine oil and o il filter must be changed according to the
mileage (ki lometers) and time intervals specified in your vehic le 's
Warranty & Maintenance booklet . Do not exceed these intervals -
harmful deposits from old engin e oil can reduce engin e perfor
mance and can lead to expensive eng ine repa irs.
Changing the oil at the recommended intervals is so very impor tant
because the lubricating properties of oi l decrease gradua lly during
normal vehicle use. If you are not sure when you have your o il
changed, ask your authorized Audi Service Advisor.
Under some circumstances the eng ine oil should even be changed
mor e frequen tly . Change oil more oft en if you drive most ly short
distances, operate the vehicle in dusty areas or mostly under stop
and -go traffic conditions, or when you use your vehicle where
t emperatures stay be low freezing po int for long per iods .
Detergent add it ives in the oi l wi ll make fresh oil look dark after the
engine has be en running for a short time. This is normal and is not
a reason to change the oi l more often than recommended .
Dam age or malfun ction s du e to lack of m aint enan ce
It is essential that you change your oil at the recommended interva ls
using on ly engine oil that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle Warranty does not cover
damage or malfunctions due to fai lure to follow recommended
maintenance and use requirements as set forth in the Audi Owner's
Manual and Warranty

Engine oil consumption
The engin e in your vehicle d ep ends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effect ive lubrication and cool ing of internal
engine components, all internal combustion engines consume a
certain amount of o il. Oil consumption varies from engine to eng ine
and may change significantly over the life of the engine . Typically,
eng ines wi th a specif ied break -in period
(see => page 2771 consume
more oil during the break -in period than they consume after oi l
consumption has stabi lized .
Under normal conditions, the rate of oil consumption 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
conditions. Further factors are the amount of oil dilution from water
co ndensation or fue l residue and the oxidation level of the o il. As
any engine is subject to wear as mileage builds up, the oil consump
t io n may increase over time until rep lacement of worn components
may become necessary .
With all these variables coming into play, no standard rate of oil consu mption can be estab lished or specified. T here is no a lternative
to regular and frequent checking of the oil level, see
Note .
If the yellow eng ine o il level warni ng symbol in the instrume nt
cluster ~ lights up, you should check the oil level as soon as
poss ible
with the oil dipstick => page 311 . Top off the oil at your
earliest
convenience=> page 312.
& WARNING
Bef ore you che ck anything in the eng ine comp artment , alw ay s
read and heed all WARNINGS
=> & in "Working in the engine
c ompartment " on
page 307 .
0 Note
Driving with an insuff ic ie n t o il level is l ikely to cause severe damage
to the engine.
[ i ] Tip s
• The oil pr es sure warning displ ay
regular inter vals, preferably ea ch time you refuel , and al ways before
going on a long trip.
• I f you have the impression your engine consumes excessive
amounts of oi l, we reco mmend that you consult your Audi dealer to
have the cause of your concern properly diagnosed . Keep in mind
t hat t he acc urate measureme nt of oil consump tion requ ires g reat
care and may take some time. Your Audi dealer has instructions
about how t o measure oil consumpt ion accurately. •
