I have achieved the feat of getting 15.5 to 16 mph consistently city. I use my cruise control to coast to a stop and accelerate, and hardly ever over 2k rpm. I have a k&n CAI and do most my driving in Panama City beach. I have a 2wd non BT crew cab titan. Gas Milage can be achieved with dicipline. And I fill my tank till after the auto shutoff every time, till gas overflows a little bit and spits at me. I don't know what I get highway yet, cause I don't highway drive much. I'm also on 20 inch rims with street tires. It's so crazy. Like everyone tells me I'm driving a gas hog and It isn't hurting my wallet more than my old frontier v6 did!(which I had to stomp alot to get power out of) sorry about my poor post structure. But, honestly gas Milage doesn't worry me much, it's really not that expensive. I spend far more in food and beer than I do to feed my titan. So buying a titan is a weight loss and fitness strategy. Who knew!
