My OM642 took 8qts to get to the top range of the dip stick as did the OM606 before it. Would be surprised if yours didn't also.

Glad they added the dip stick back on the OM642, sensors go out and get dodgy and are silly except as a low oil warning system IMO.

I'd rely on the dip stick if you have the factory tool.
