FRS- intake, exhaust, tune etc.... All that has made my MPG worse over time. My MPG read out in the display is a filthy dirty liar and says 29ish MPG. There's lies, damn lies and the MPG read out on your car.

I do the calculation by hand and get at best 27, at worst 25. On a recent trip to TN, on open highway all the way on a full tank I did get over 30- going 65 (cops everywhere in GA) with few stops. I got a little under 25 in the mountains of TN having fun on the Tail and cruising around

Half highway from 60-90 (long bridge on my commute) and half city/stop and go. Yeah I do have a tendency to DILYSI at times.

I'm still trying to get the balance right on my car. Between the battery and the bag of groceries in the front seat sometimes, things get thrown completely off.

Just managed 28.83 MPG on my last fill up.

28.7 since i bought the car 6 months ago. On the freeway i use cruise control a lot, but on surface streets i tend to gun it and have fun. I usually get up near redline at least once or twice for every tank of gas and hit at least 5k every time i drive unless its a short trip. gas mileage is actually probably slightly better than stated since i have 18" rims which throws off the speedo/odo a bit.

I know everyone hates dragging these threads back up but after two tanks of a my normal commute getting 27.5mpg I finally did a long motorway trip with the cruise set at 75mph for the majority of the time, I was pretty astonished to get 33.3mpg.

Even better, I think if you consumed the entire tank on an interstate I can now see 34-35mpg being a very real possibility!
