Had a few days/50 miles of poor mpg, around the 40mpg mark. My car seems to bounce from 47-49 mpg at it's best to 40-42mpg at it's worst (regenning) on my commute, averaging 44-45mpg for the tank. The car is a lot looser, so I might find myself putting my foot down a little more when conditions allow. Still poor that my car is noticeably regenning for around 40 miles every 250 miles or so and the oil temp variance between regenning (car touched 101C yesterday) and not (90C at low load, 92 at high load) seems larger than it was in the Scirocco. Maybe regens would be less frequent if the car's normal running temp was a little higher. Seems a daily commute of 12 miles is not quite enough to keep the regens at bay, but 15 miles each way is (when I was going to Benfield for warranty work).
