Nice. yea your mpg will improve to at least 18. BTW if you are concerned about gas mileage etc, just try and figure out how much you expect to drive the car, figure 18 mpg for a low end ballpark and then calculate your estimated annual fuel cost based on how much you think you'll pay on average per fill up, and then you will have a good idea of how much gas you'll use per year and how much it'll cost you. Then, you can forget about it and enjoy the car and just know that is how much it will cost instead of watching the MPG meter change as you go up a hill or give it gas and go
