22 8 Ch e ck ing and filling
current list of oils (manufacturers , brand
names etc.) that conform to Audi oi l standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine).
Changing t he eng ine oil
The engine oil and oil filter must be changed
according t o the m ileage (ki lomete rs) and
time inte rvals 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 inte r-
vals is so very important because the lubricat-
ing properties of oi l decrease grad ually 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, 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 fo r
long periods.
Detergent addit ives in the oil w ill make fresh
oil look dark after the engine has been run-
ning fo r a short time. This is norma l and is not
a reason to change the oil more often than
recommended.
Damage or malfun ctions due to lack of
maint enance
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 wit h gasoline engine) or
VW 507 00 (vehicles with diesel engine) . Your
Limited New Vehicle Warranty does not cover
damage or malf unctions due to failure to fol-
low recommended maintenance and use re-
qu irements as set forth in the Audi Owner's
Manual and War ranty
& Maintenance book let.
Your dealer will have t o 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
t imely manner.
Engine oil consumption
The engine in your vehicle depends on on ade-
quate amount of oil to lubricate and cool oil
of its moving ports.
In order to provide effective lubrication and
cooling of interna l engine components, all in-
ternal combust ion engines consume a certain
amount of oil. Oil consumpt ion varies from
engine t o engine and may change sign ificantly
over the life of the engine. Typically, engines
with a specified break-in period (see
¢ page 201) consume more oil during the
break-in period t han they consume afte r oil
consumption has stabilized.
Under normal cond it ions, the rate of oil con-
sumption depends on the quality and viscosity
of the oil , the RPM (revol ut ions per minute) at
which the engine is operat ed, the ambient
temperature and road conditions . Furt her fac-
tors are the amount of oil dilution from water
condensation or fue l residue and the oxida-
tion level of the oil. As any engine is subject to
wear as mileage builds up, the oil consump-
t ion may increase over t ime until replacement
of worn components may become necessary.
With all these variab les coming into play, no
standard rate of oil consumpt ion 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
in the instrument clust er
II lights up, you
shou ld check the oil level as soon as possib le
