So you are saying, everytime I add a quart of oil, there is a sensor that records it. Not to mention oil changes.
I can hardly imagine.
There must be sensors in the crank case or oil pan all the way from bottom to top.
I did go to the dealer and get the records on the oil changes.
Never occured to me to ask for the record of quarts added.
Thanks for the enlightenment.

Dear Paulwho-
Thank you for the well of information.
Hopefully I will grow to appreciate this Mercedes as much as my Honda's.
