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
