smoothly and reliably. Choosing the right oil
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 special quality standard for engine oil that
will help assure that your vehicle's engine 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 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 time 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-
posit s 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 specificat ion, 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 - and no oil that expressly
conforms to Audi oil standard VW 502 00
specifications is available - may you top off
with a high quality engine oil , preferably syn-
thetic-based, that meets ACEA A3 or API SM
specifications, but even then, only in viscosity
grades SAE 5W-40 , SAE SW-30, or SAE
OW-40. However, during the entire time be-
tween 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 specification
vw
502 00.
For more information about engine oil that
has been approved for your vehicle, please
contact either your authorized Audi dealer or

or visit our web site at www.audiusa .com or

current list of oils (manufacturers, brand
names etc.) that conform to Audi oil standard
vw

Changing the engine oil
The engine oil and oil filter must be changed
according to the mileage (kilometers) and
time intervals specified in your veh icle'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
