I have a 15 sv cc 4x4 and I get about 16mpg on average over the 10k I have had it. I play plenty, but I learned from years with my 06 kc that mashing the pedal killed the mpg. Most of my driving is back roads and town driving, with the exception of a few trips. I have a bullydog gt, s&b cai, and run 87 at the pump. I also have a roof rack and run 33" duratracs. I think the mileage is there if you keep your pedal off the floor.
