Engine oilChecking oil level1. Park the vehicle on a level surface
2. Shut the engine off after it has
reached normal operating tempera-
ture
3. After approx. 5 minutes, pull the
dipstick out and wipe it off with a
clean lint-free cloth, paper towel, or
similar material
4. Carefully push the dipstick all the
way into the guide tube and pull it
out again
5. The oil level should be in between
the two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.390de647
The oil volume between the two marks
on the dipstick corresponds to approx.
1.1 US quarts (1 liter). Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine.460de189
Adding engine oilWhile you should wait until the level has
dropped to just above the lower gradu-
ation before adding oil, you should
never allow the oil level to fall below
this marking.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This is also true for the
manual transmission, the automatic
transmission, the differential, and the
power steering system.<
Recommendation: have the oil changed
by your BMW center only.390de626
