Speaking of dip sticks and idiot lights...

Does anyone know (or have a good idea) why BMW recommends waiting until the 35d engine is a full quart low before adding oil?

Some possible 'reasons'...
It is dangerous to over fill a diesel engine.
It makes it easy to just 'add a quart'.
It reduces the number of times owners show up at the dealer for them to add a little oil.
They don't want us to get our pretty little fingers dirty checking the oil level with the obscurely located dip stick.

Call me old school but I feel like I've neglected any of my vehicles that get a full quart low before I top it up.
