I recently had the 30,000 mile maintenance work done on my 09 Forester. This was on January 20th. Before having this work done I was averaging anywhere from 27 to 30 mpg driving to and from work. (I work 2 hours from where I live and drive back country 55mph highways) After the maintenance work I am now only getting 22 to 25 mpg. I have since had it back into the dealership twice for that problem and they have told me there is nothing wrong with my car. The 2nd time I was up there they hooked it up to the scanner and they reset the emissions values (I think is what they said they did) with no change. I called 2 other dealerships who have said that they have no idea what could be causing the problem and the place I bought it from can't figure it out either. I bought the car 1. because of the drive and I needed something better for winter and 2. because I heard nothing but great things about the MPG. Has anyone else with an 09 Forester had this same problem? Or even any other model. If so what was done or what was wrong with it? Any help would be greatly appreciated. I have to take it back in next Tuesday for them to once again look at it. And I'm hoping that maybe I'll find an answer for them to fix.
