I only have 3300 miles on my 09. When I passed 1200 miles the fuel mileage improved by 8-9 mpg from one tank to the next. Funny thing was I was running in the mountains when the mileage improved. I figure the engine is still tight and it will improve with age. I currently get about 43-45 mpg, don't do a lot of WOT stints, and it's all stock.
