Hi All, I recently purchased a 2012 with the Ecoboost thinking I would average low to mid 20s mpg. After about 3 months I am averaging 17.3 mpg:( Can someone give a me a checklist, in order, of things to look for that would be causing such poor fuel economy? For example: 1) Check tire pressure 2) Check tire alignment 3) etc I'd really like to get this solved as I love the car but am going to get rid of it if I can't get better mpg.
