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
The engine oil and oil filter must be changed
according to the mileage (kilomete rs) 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 addit ives 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
Checking
and filling

the form of Service or Repair Orders that all
scheduled maintenance was performed in a
timely manner.
Engine oil consumption
The engine in your vehicle depends on an ade-
quate amount of oil to lubricate and cool all
of its moving parts.
In order to provide effective lubrication and
cooling of internal engine components, all in-
ternal combustion engines consume a certain
amount of oil. Oil consumption varies from
engine to engine and may change significantly
over the life of the engine. Typically, engines
with a specified break-in period (see
¢ page 204) consume 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 oil , the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road conditions . Further fac-
tors are the amount of oil dilution from water
condensation or fuel residue and the oxida-
tion level of the oil. As any engine is subject to
wear as mileage builds up, the oil consump-
tion may increase over time until replacement
of worn components may become necessary.
With all these variables coming into play, no
standard rate of oil consumption can be es-
tablished or specified. There is no alternative
to regular and frequent checking of the oil lev-
el, see Note .
If the yellow engine oil level warning symbol

should check the oil level as soon as possible

convenience 9 page 232.
