Engine oil consumption
The engin e in your v ehicl e dep ends on an ad e­
quat e amount of oil to lubricate and cool all of
its moving parts.
In order to provide effect ive lub rication and cool­
ing of inte rnal engine components, all inte rnal
combustion engines consume a certain amount
of oil. Oil consumption varies from eng ine to en­
gine and may change significantly over the life of
the engine. Typ ically, engines w ith a specified
break -in period (see
c> page 86) consume more
o il dur ing the break-in per iod than they consume
after oil consumption has stabilized .
Under normal cond itions, the rate of oil con­
sumption depends on the qua lity and viscos ity of
the oil, the RPM (revolutions per m inute) at
which the engine is operated, the amb ient tem­
perature and road condi tions. Further facto rs a re
the amo unt of oil di lution from water co ndensa­
tion or fue l resid ue a nd the oxidation level of the
oi l. As any engine is subject to wear as mileage
builds up, the oi l consumption may increase ove r
time unt il replacement of worn components may
become necessary.
With a ll these variab les coming into play, no
standard rate of oi l consumption can be estab­
lished or spec ified . There is no alternative to reg­
ular and frequent checking of the oi l level, see
Note .
If the y ellow engine oil leve l warning symbo l Bl
in the instrument cluster lights up, you should
check the o il level as soon as possible

venience
