Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil .
-
The engine in your Audi is a sophisticated
powerp lant that was b uilt to exacting specifi ­
cations . This engine needs the right kind of
engine o il that meets specificat ions regarding
q ua lity and viscos ity so that it can run
smoothly and reliably . Choos ing the right oil
and changing oil within the time and mileage
in terva ls pr inted in your veh icle's War ranty
&
M aintenance book let matters a lot more to­
day than i t did yea rs ago . Audi has developed
a special quality s tanda rd fo r engine oil th at
will he lp assure that your veh icle's eng ine will
get the lubrication it needs for prope r opera ­
tion .
M odern eng ine lubrica tion has taken a qu an­
tum leap in the last few years . Many synthetic
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 A udi.
Checkin g and fillin g 231
Whether you use synthetic o r petro le um­
based engine oil, the oil that you use m ust

VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles w it h diesel eng ine) to
help keep your veh icle's engine ru nning
smoot hly and he lp prevent the format io n of
harmful deposits, sometimes ca lled "s ludge, "

Viscosity
Engine o ils are graded accord ing to their vis­

engine depends o n climactic or seasona l con­
ditions where you d rive. You ca n use o il wit h a
vis cosity gr ade of SA E SW40 across all tem ­
pera ture ranges for norma l driv ing con ditions.
Howeve r, if engine oil v iscos ity grade SA E
SW40 is not available, you can a lso use v iscos­
i ty grade SA E SW -30 or SA E OW -40 as long as

232 Check ing and filling
when you need it, we strongly recommend
that you always carry with you an extra quart (liter) of o il that expressly conforms to the
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (veh icles with diesel engine) spec­
ification, in case you have to top off the oil
while o n the road .
Applies to veh icles w ith g asol ine eng ine on­
l y:
Only if the level of the oil is at or below the
minimum mark on the oil dipstick - and no oil
that expressly conforms to Aud i oil standard
VW 502 00 specif ications is avai lab le - may
you top off with a high quality eng ine oil, pref­
e rably synthetic -based, that meets ACEA A3
or AP I SM specifications, but even then, only
in viscosity grades SAE SW-40, SAE SW-30, or
SAE OW-40. However, during the entire time between oi l change interva ls, never top off
with more than a total of 0.5 qt/liter eng ine
oil that does not conform to Audi oil specifica­
tion VW 502 00 .
Applies to veh icles with diesel engine onl y:
Only if the level of the oil is at or below the
minimum mark on the oil dipstick - and no oil
that expressly conforms to Aud i oil standard
VW 507 00 specifications is available - may
you top off with a high quality eng ine oil, that
meets AC EA C3 or A PI CF specifications, but
even then, only in v iscosity grades SAE
SW-40, SAE SW-30, or SAE OW-40 . However,
during the entire time between oil change in­
tervals, never top off with more than a tota l

Changing th e engine oil
The eng ine oi l and oil fi lter m ust be changed
according to the mileage (kilometers) and
t ime intervals specified in your veh icle's War ­
ranty
& Maintenance booklet. Do not exceed
these interva ls - harmful deposits from old
engine oil ca n reduce engine performance and
can lead to expensive e ngine repa irs.
Changi ng the oil at the recommended inter­
vals is so very important because the lubricat­
ing propert ies of oil decrease gradually during
normal veh icle use . If you are not sure when
you have your oil changed, ask your author­ ized Audi Serv ice Adv isor.
Under some circumstances the engine oil
should even be changed more frequent ly .
Change oil more often if you drive most ly
sho rt distances, operate the ve hicl e in dusty
areas o r most ly unde r stop-and-go traff ic con­
ditions, or when you use your vehi cle where
temperatures stay be low freezing point for
long pe riods .
Detergent addi tives in the oil will make fresh
o il 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 t han
recommended.
