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 inte rnal engine components, all in-
~ ternal combustion eng ines consume a certai n ,....,

amoun t of oil. Oil consumpt ion varies from
engine to engine and may change significantly
over the life of the engine . Typically, engines
with a spec ified break-in period (see
¢
page 193) consume more oil during the
break -in period than they consume after o il
consumption has stabilized .
U nder normal cond itions, the rate of oil con ­
sumption depends on the quality and viscos ity
of the oil, the RPM (revolutions 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 tion or fue l resid ue an d the oxida­
t ion level of the o il. As any engine is subject to
wear as mi leage b uilds up, the oil consump ­
tion may increase over time until replacement
of worn components may become necessary.
With a ll these variab les coming into p lay, no
standard rate of oil consumption can be es ­
tablished or specified. There is no alternative
to regular and frequent check ing of the o il lev ­
el, see
Note .
If the yellow engine oil leve l warning symbo l
El in the instrument cl uster lights up, you
sho uld check the oil leve l as soon as possib le
