Engine oil consumption
Th e e ngin e in your v ehi cle dep ends on an ad equate
amount of oil to lubricate and cool a ll of its movin g parts.
In order to p rovide e ffect ive lubric ation and cooling of inter na l
eng ine components, all internal combust ion eng ines consume a
c ert ain a mo unt o f oil. Oil co nsump tion va ries from e ngine to eng ine
and may change sign ifican tly over the li fe of the engine . Typically,
eng ines w ith a sp ecifie d brea k-in period (s ee =>
page 261) co nsum e
more o il dur ing the break -in period t han they cons ume a fter oil
cons umption has stabilize d.
Under norm al cond itions, th e ra t e of oil con su mp tio n depe nds on t he
quality and v iscosi ty of the oil, the RPM ( revolutions pe r minute) at
w hich the engi ne i s op erate d, the ambie nt te m pe ratu re and r oad
conditions. Further factors are the amount of oi l di lution from water
co ndens ation or f uel re sidue and th e oxid ation level of the oil. As any
eng ine is s ubject to wear as mileage builds up, the oil consumption
may increase over time until replacemen t of wo rn components may
become necessa ry .
With all these varia bles comin g into play, no stan dar d rate of oil
co nsum ption can be establis hed o r spe cified. Th ere is no alte rnative
to regular and frequent chec kin g of the o il level, see
Note .
If the yellow e ngine oil leve l w arning symbol in the ins trumen t

[ i ] Tips
• The oil pressure warn ing display 'e.::1; is not an indicator of the oil
level. Do not rely on it . Instead, check the oil level in your engine at
regular intervals, preferably each time you refuel, and always
before going on a long trip .
• If you have the impression your eng ine consumes excessive
am ounts of o il, we recom mend that you cons ult your Audi dea le r to
have the cause of your concern properly d iagnosed. Keep i n m ind that
t he accurate meas urement of oil co nsum ption re quires great care
and may take some t ime. Your Audi dealer has instruct io ns about how
t o meas ure o il cons umption a ccu ra tely .•
