 I am a true car person. I have owned way to many new cars over the years and this is truly the best.  The first thing to do for gas mileage is to change the air filter to the K&N.  Use Mobil 1 oil and my mileage has ran as high as 41MPG when trying.  I get a constant 30MPG when my wife drives and that is great.  She just drives and does not worry about mileage.  She has never gotten any better than 17MPG with any other car that she has had both large and small cars of many makes and models.  Thank you Ford for taking a large step for fuel. The others have a lot of catching up to do. Ford rules
