Motor- checking oil level
Like fuel consumption, engine oil con-
sumption depends on driving style
and operating conditions.
The oil level should therefore be
checked regularly, approximately
every 1000km (approx. 600 miles), or
sooner if the car has been driven
hard. The car should stand on a flat,
level surface.
Maximum measuring accuracy:
Before a cold engine is started.
If the engine is already at its normal
operating temperature, wait a short
time so that the oil can drain back in
the sump (for instance while refuel-
ling).
Push the dipstick fully into its tube.
Examine the oil level: it must be
between the two dipstick marks.
Motor- adding engine oil
Do not add more oil until the level has
fallen almost to the lower mark on the
dipstick. However, the oil level must
not fall below the minimum level mark.
The space between the two dipstick
marks represents approx. 1 litre
(1.8 Imp. pints) of oil. Never add oil
beyond the upper dipstick mark. Add-
ing too much oil will harm the engine
because it will be burned off more
rapidly, thereby implying that con-
sumption was too high.
BMW engines are designed not to
need separate additives in the engine
oil, and adding these substances
could even be harmful. The same
applies to the gearbox or automatic
transmission, the final drive and the
power steering.
