My 2010 is still breaking in and getting about 24 mpg. I do drive a lot and with the cost of gas, is there any modifications that can be done to improve mileage? Thanks

 

Lighten your shoes and feet. lol
Really, you have a heavy car with a blunt shape. Comparatively speaking the engine has to make more power to make the car start from a stop, and has to make more power to keep it going. The only thing that will make the fuel economy any better, is to take driving lessons from granny. Most of the stuff you see advertised that promises better fuel economy is a lot of BS. Keep the tires inflated to factory spec, and use the recommended lubricants.
