Ok - was just going on my experience with my E350 where it just got better and better consumption wise over the years - best I ever had was just before I sold it around 65,000 miles. Perhaps I just drove it more carefully!Not really anymore, the tolerances are far better than they were years ago and there isn't the losening up effect there was in cars from the 70-s to 90's. You should be at optimal economy within a thousand miles with a modern car.
