What how are you all getting such good fuel economy. I only get 14mpg. I have a 2007 Ford Fusion SEL V6 AWD. I went to Ford and they said well there are no check engine lights on dash so there is nothing they can do. They want me to record the next time i put gas in the tank and how many kms it gets me, it pisses me off I told them it costs me $70 a week in gas and that gets me 186 miles.
