I have the 08 Nismo 4x2 and my best mileage has been like 23 at about 75, no more than 75, on the straight (and flat) highway to Las Vegas. Doesnt do to good once hills come into play though. The gearing is absolutely gay, even to switch lanes to pass someone who gets in the way for no reason (god that pisses me off) the truck dropps a gear and revs up more than a v6 should just to pass. My father in law has the TRD Tacoma, like 08 or 09, and you cant even tell the engine has accelerated when he passes people on the freeway, you just feel the pull!!!
