The engine oil and oil filter must be changed
according to the mileage (kilometers) and
time interva ls specified in your vehicle's War-
ranty & Maintenance booklet. Do not exceed
t hese 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
norma l 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, ope rat e the vehicle in dusty
areas or mostly under st op-and-go traffic con-
ditions, or when you use your vehicle whe re
temperatures stay below freezing point for
long periods.
Detergen t add itives in t he oil will make fresh
oil look dark after the eng ine has been run-
ning for a short time . This is norma l and is not
a reason to change the oil more often than
recommended.
Damage or malfunction s due to lack of
maintenance
It is essen t ial that you change your oil at the
recommended inte rvals using only engine oil
that complies with Audi oil standard
VW 502 00 . Your Limited New Vehicle War-
ranty does not cover damage or malfunctions
due to failure to follow recommended mainte-
nance and use requirements as set forth in
t he Audi Owner's Manual and Warranty &
Maintenance booklet . Your authorized Audi
deale r will have to deny warranty coverage un-
less you present to the dealer proof in the
form of Service or Repair Orders t hat all
sched uled maint enance was performed in a
time ly 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 interna l eng ine components, all in-
te rnal combust ion engines consume a certain
amount of oil. Oil consumpt ion varies from
engine to engine and may change significan tly
over the life of the engine. Typically, engines
with a spec ified break-in period (see
¢
page 150)
consume more oil duri ng the
break-in period than they consume afte r oil
consumption has stabili zed.
Under normal cond itions , the rate of oil con-
sumption depends on t he quality and viscosity
of the oil, the RPM (revolut ions per minute) at
which the engine is operated, the ambient
temperature and road conditions. Further fac-
tors are the amount of oil dilut ion from water
condensa t ion or fue l residue and the oxida-
tion level of t he oil. As any eng ine is subject to
wear as mileage builds up, t he oil consump-
t ion may increase over time until repla cement
of worn components may become necessary.
With all these variables coming into play, no
standard rate of oil consumpt ion can be es-
t ablished or spe cified . There is no alte rnative
to regular and frequent checking of the oil lev-
el, see
Note.
