For the first couple of tanks after the recall service I noticed a 2 MPG drop during my usual commute (75-80% highway). Then the car went through a few burn off cycles (where, after you park, the engine appears to be burning off excess soot/particulate matter). Since then, it has improved a little -- I'm within 1 MPG of my average from before the service.
I'm trying to build a map of stations selling premium diesel fuel:,41.52832&z=5 . If you know of any in your area, please contact me and I'll add them to the list.
