Filled up my first recordable tank today since I bought this truck. 319 miles, 14.2 gallons, about 22.5 mpg. Now I gotta get the ultragauge dialed in.
Believe it or not, I'm stoked. It can only go up from here! Temperature never reached 40F during the whole tank and it's been in the teens every morning for a week, so of course winter gas as well; about 40 miles were at 74 mph; it has the dealer's 5w30 conventional oil in the sump; and it's riding on all terrain tires that roll like sandbags. LOTS of room for improvement.
