Again it still depends on ambient conditions, driving style and time.
I was wondering how you knew all that about the FSS computer, etc. You have been reading the Merc manuals. How does the computer know that the car has been sitting for 6 mths or so. Is there a running timer, clock that keeps track of date, etc.?
and if this is the case, presumably it will continue timing with the battery disconnected.
