Nobody buys a Mustang for gas mileage, not 2010s, 2011s or 2015s... As another member posted, for gas mileage buy a Prius. I was asking to check if my car was behaving normally. I don't expect 40 MPG, but I expect what other member are getting, 18,19,20 MPG.

Be sure you're resetting the on-board at each fill-up. By not resetting it, it's only giving you a running average from the last time it was reset. The on-board is typically off by 1-2 MPG but a rare few are pretty close. Hand calculate your mileage. Also, there are so many variables that you can drive the same stretch of road under near identical conditions and still vary by 2-3 MPG's or more. I've been keeping strict fuel mileage records for over the last 1,200,000 miles and I can tell you that the only valid method is to average your hand-calculated fuel mileage each month and to take into account and document any variables that you encounter. Since the BTU content and quality of fuel will vary from tank to tank, it's a real crapshoot.
It's not uncommon for a V6 to get what appears to be lousey fuel mileage if you're doing mostly city driving.

mine has 5.3k miles annd I'm hitting well under 20mpg. I'm gonna see how I do on my way down to florida. Hopefully by then I will have a tuner combo. On a side note, has anyone purchased the JLT CAI and used it on a 2010?

Once you get away from steady-state cruising in the 1500-1800 RPM range on flat smooth roads and ethanol-free fuel, mileage will drop well below the EPA ratings. Even steady state cruising in hilly terrain will cause rather drastic fuel mileage changes. ANY load on the engine beyond steady-state flat cruising and kiss all of those alluring numbers goodbye.
