The reason for this is that the crankshaft counterweights are splashing vigourously in the oil when the engine is running, which will push oil up the dipstick a ways.
When checking oil, NEVER use the newly withdrawn dipstick as representing the actual oil level. Put it in after wiping it off, wait 1 minute then withdraw it, to get a proper reading.
I did it the proper way. Except because I had just changed oil, only engine was warm, not oil. I was checking that I had put in the correct amount.
To be honest, I had not read the manual. But I just did, and that is how I would check oil level on any car.
What I was saying, is that I get a high reading first time I check by inserting cleaned dipstick. Then if I repeat the clean and insert, subsequent readings are all lower. Can only think that first time some oil on side of tube gets deposited on stick first time it is inserted. Either way, I am either 90% full or 75% full! But will check it again (haven't driven car since oil was changed).
BTW - Just got a flyer from West Marine - They have their vacuum oil extractors on sale for $59.95. 6.5L, I believe. I have a larger unit of similar design made by Mity-Vac. It sucks and discharges. Great unit - I have had it for quite a while and use it on all cars except my SL (which has to be drained). On most MBs, the oil can be sucked up the diptube - that is how many shops do it. I imagine that is how MB intended cdi engine to be done too, although it seems a little extra oil can be sucked out by inserting tube all the way.
