Engine oil
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 built to exacting specifi­
cations . This engine needs the r ight kind of
engine o il that meets spec ificat ions regarding
qua lity and viscos ity so that it can run
smoothly and reliably . Choos ing the righ t oi l
and changing oil within the time and mileage interva ls printed in your vehicle 's Warranty
&
Maintenance book let 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 veh icle's eng ine 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 ava ilable today provide better engine lu­
brication that can outlast trad itional petrole -u
m -based oils, making them a smart choice
for use throughout the life of your Audi.
Whether you use synthet ic o r petro le um­
based eng ine oil, the oi l that you use m ust
conform to Audi's oi l quality standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with d iese l eng ine) to
help keep your veh icle's engine running
smoothly and help prevent the format ion of
harmful deposits, sometimes called "s ludge,"
that over time can lead to expens ive repairs.
At the time of printing, engine oils ava ilab le in
the U.S. and Canada that meet the exacting
specifications of Audi oil standard VW 502 00 (ve hicles w ith gasoline eng ine) o r VW 507 00
(veh icles w ith diese l eng ine) are synthet ic en­
gine o ils . This does no t mean, howeve r, that
every synt hetic eng ine oil will meet A udi oi l
standard VW 502 00 (veh icles with gasoline
engine) or VW 507 00 (vehicles with diesel
engine). So a lways be sure that you use an ap­
proved o il.
T o he lp preven t the formation of harmfu l de­
posits use on ly oil with the following specifi­
cations printed on the o il container:
- Audi oil standard VW 502 00 (g aso line en ­
gine )
- Audi oil standard VW 507 00 (die sel en-
gine )
Oil container labels may car ry the spec ifica­
t ion sing ly or in combination with othe r desig­
na tions and oil quality standa rds.
Viscosit y
Engine oi ls are graded according to their vis­
cosity . The proper viscos ity grade oil for your
engine depends on climactic or seasona l con­
ditions where you drive . You can use o il with a
viscosity grade of SA E 5W40 across all tem­
perature ranges for normal dr iv ing cond itions .
However, if engine oil viscosity grade SAE
5W40 is not ava ilable, you can also use v iscos ­
i ty grade SAE 5W-30 or SAE OW-40 as long as
it meets Audi oil quality standard VW 502 00
(ve hicl es w ith gasoline eng ine) o r VW 50 7 00
(ve hicles w ith diese l engine) specifica tions. .,.

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 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine) spec­ ification, in case you have to top off the oil
while on the road .
Applies to vehicles with gasoline engine on­
ly:
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 Audi oil standard
VW 502 00 specifications is available - may
you top off with a high quality engine oil, pref­ erably synthetic-based, that meets ACEA A3
or API SM specifications, but even then, only in viscosity grades SA E SW-40, SAE SW-30, or
SAE OW-40 . However, during the entire time
between 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 specifica­
tion VW 502 00 .
Applies to vehicles with diesel engine only:
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 Audi oil standard
VW 507 00 specifications is available - may
you top off with a high quality engine oil, that
meets ACEA C3 or API CF specifications , but
even then, only in viscosity 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 total
of 0.5 qt/liter engine oil that does no t con­
form to Audi oil specification VW 507 00 .
For more information about engine oil that
has been approved for your vehicle, please
contact either your authorized Audi dealer 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 oils (manufacturers , brand
names etc.) that conform to Audi oil standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine).
Changing the engine oil
Checking and filling 235
The engine oil and oil filter must be changed
according to the mileage (kilometers) and
time intervals specified in your vehicle'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
you have your oil changed, ask your author­ ized Audi Service Advisor.
Under some circumstances the engine oil
should even be changed more frequently. Change oil more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
ditions, 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 run­
ning for a short time. This is normal and is not
a reason to change the oil more often than recommended.
Damage or malfunctions due to lack of
maintenance
It is essential that you change your oil at the
recommended intervals using only engine oil
that complies with Audi oil standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine). Your
Limited New Vehicle Warranty does not cover
damage or malfunctions due to failure to fol­
low recommended maintenance and use re­
quirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet.
Your dealer will have to deny warranty cover­
age unless you present to the dealer proof in
the form of Service or Repair Orders that all
scheduled maintenance was performed in a
timely manner.

Engine oil consumption
Th e e ngine in your vehicle depends on an ad e­
quate amount of oil to lubricate and cool all
of its moving parts.
In o rder to prov ide effec tive l ubrication and
c o oling of i nternal engi ne components, all in­
t e rnal com bustion eng ines consume a certa in
a m ount of o il. O il consumption var ies from
engine to eng ine and may change significant ly
ove r the life o f the eng ine . T ypica lly, eng ines
with a specified break -in per iod (see
<=>
page 207) cons ume more oil during the
break -in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil con ­
sumption depends on the quality and viscosity
of the oi l, the RPM (revo lutions per minute) at
which the engine is operated, the ambient
temperature and road condit ions. Further fac­
tors are the amount of oil d ilution from water
condensation or fuel residue and the ox ida ­
tion level of the oil. As any engine is subject to
wear as mileage bu ilds up, the oil consump­
tion may in crease over t ime un til replacement
of worn componen ts may become necessa ry.
W ith all these var iables coming into play, no
standa rd rate of o il consumption can be es­
tablished or specified. The re is no alterna tive
to regular and frequen t checking of the oi l lev­
e l, see
Note .
If the ye llow eng ine o il level warn ing symbol
in the in strumen t cluste r
II lights up, you
should c heck t he o il level as soon as possible
<=> page 236 or ¢page 237. Top off the oi l at
your ea rliest convenience <=>

(D Note
Driving with an insufficient oi l level is like­
ly to ca use severe damage to the eng ine.
-
(D Tips
- The oil pressure warn ing display. is
not an indicator of the oil level. Do not
r ely on it. Instead, check the oil level in
your engine at regular intervals, pref­
erably each time you refuel , and always
before going on a long trip .
-If you have the impression your engine
cons umes excessive amounts of oil, we
recommend that you consult your Aud i
dea ler to have the cause of your con cern
prope rly d iagnosed. Keep in m ind that
t he accurate meas urement o f oil c on­
sumption requ ires great care and may
take some t ime. Your Audi dea le r has in­
struct ions about how to measu re oil con­
sumption acc urately.
Checking the engine oil level
