09 Sport with more than a few mods. I avg around 22 in town and on the highway was pushing 40mpg. That's if all hwy. As you can see my avg speed was ummm up there. Beats driving a Prius at any mpg.
My 05 Frontier Nismo gets 15.9 regardless. Same with 4wd or 2wd. Used to be 16.9 but got knocked slightly when I went to 17" wheels and BF Duratrack meaty tires. Still happy with that considering. Can't live in CO without a mountain/winter truck.
