Changing the engine oil
The engine oil and oil fi lter must be changed according to the mileage
(kilometers) and t ime intervals specified in your vehicle 's Warranty
&
Maintenance booklet . Do not exceed these interva ls -harmful
deposits from o ld engine oil can reduce engine performance and can
lead to expensive engine repairs .
Changing the oil at the recommended intervals is so very impo rtant
because the lubricating properties of o il decrease gradually during
normal vehicle use. If you are not sure when you have your oil
changed, ask your author ized Audi Service Adv isor .
Under some circumstances the engine oil should even be changed
mo re frequently. Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or mostly under stop­
and-go traffic conditions, or when you use your vehicle where temper­
atures stay be low freezing point for long periods.
Detergent addit ives in the oi l wi ll make fresh oil look dark after the
engine has been running for a short t ime. 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 oi l that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle War ranty does not cover
damage or malfunctions due to fai lure to follow recommended main­
tenance and use requirements as set forth in the Audi Owner 's
Manual and Warranty
& Maintenance booklet. Your dealer will have
to deny warranty coverage unless you present to the dealer proof in
the form of Serv ice or Repair Orders that all scheduled maintenance
was performed in a time ly manner. •
Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effective lubrication and cooling of internal
eng ine components, all inte rnal combustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change sign ifican tly over the lif e of the engine. Typically,
engines with a specified break- in period (see~
page 251) consume
more oil during the break-in period than they consume after oil
consumption has stab ilized .
Under normal conditions, the rate of oil consumption 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 factors are the amount of oil dilution from water
condensation or fuel residue and the ox idation level of the oil. As any
eng ine is subject to wear as mileage builds up, the oil consumption
may increase over time until replacement of worn components may
become necessary.
With all these variab les coming into play, no standard rate of oil
consumption can be established or specified . There is no alternative
to regular and frequent checking of the oil level , see
Note .
If the yellow engine oil leve l warning symbol in the instrument
cl uster lights up, you should chec k the oil level as soon as possible
with the oil dipstick~ page 283. Top off the oil at your earliest
convenience ~
