prevent the formation of harmful deposits, sometimes called
"sludge", that over time can lead to expensive repairs.
At the time of printing, engine oi ls 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 deposits use only oil with
the fo llowing specifications pr inted on the oil container:
A ud i oil stan dard VW 50 2 0 0
Oil container labels may carry the specification singly or in combi­
nation with other designations and oil quality standards.
V isc osi ty
Engine oils are graded according to their viscosity . The proper
viscosity grade oil for your engine depends on climactic or seasona l
conditions where you drive. You can use oil with a viscosity grade of
SAE 5W40 across all temperature ranges for normal dr iving condi ­
tions.
However, if engine 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 qua lity standard VW 502 00 specifications .
Because engine oil that meets the Audi oil standard may not be
avai lable everywhere when you need it, we strongly recommend
t hat you a lways carry with you an extra quart ( liter) of oil that
express ly conforms to the VW 502 00 specification, in case you have
t o top off the oil while on the road .
On ly if the 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 oil standard
VW 502 00 specifications is available -may you top off with a high
quality engine oil, preferably synthetic -based, that meets ACEA A3,
ACEA A5 or ACEA B5, API S L or ILSAC GF -3 specifications, but even
then, on ly in viscosity grades SAE 5W -40, SAE 5W -30, or SAE 0W -40.
However, during the ent ire time between oi l change intervals, never top off with more than a total of 0
.5 qt/ liter engine oi l that does not
conform to Audi oil specification VW 502 00.
For more information about engine oi l that has been approved for
your vehicle, p lease contact either your authorized Audi dea ler or
Audi Customer Relations at 1 (800) 822-2834 or visit our web site at
www.audiusa.com or www.audicanada.ca. Here you will also find a current list of o ils (manufacture rs, brand names etc.) that confo rm
to Audi oil standard VW 502 00.
Changing th e engine oil
The engine oil and oil f ilter must be changed according to the
mi leage (ki lometers) and time intervals specified in your vehic le's
Warranty & Maintenance booklet. Do no t exceed these intervals -
harmfu l deposits from old engine oil can reduce engine perfor­
mance and can lead to expensive eng ine repa irs.
Changing the oil at the recommended intervals is so very important
because the l ubricating properties of oi l decrease gradua lly during
norma l vehicle use. If you are not sure when you have your oil
changed, as k your authorized Audi Service Advisor.
Under so me circumstances the engine oil should even be changed
more frequently . Change oil more often if you drive mostly short
distances, opera te the vehicle in dusty areas or m ostly under stop­
and-go traffic conditions, or when you use your vehicle where
temperatures stay below freezing point for long periods .
Detergent additives in the oil will make fresh oil look dark after the
engine has been running for a short time. This is normal and is not
a reason to change the oil more often than recommended.
D amag e or malf unct ions due to la ck of maintenan ce
It is essential that you change your oi l at the recommended intervals
using on ly engine oil that complies with Audi oil standard
VW 502 00. Your Limited New Vehic le Warranty does not cover
damage or malfunctions due to failure to fol low recommended
maintenance and use requirements as set forth in the Audi Owner's
Manual and Wa rranty & Maintenance booklet. Your dea ler wi ll have
to deny warranty coverage unless you present to the dealer proof in _,.
