My 5.0L SuperCrew has landed me a 541 mile tank once, on 26.2 Gallons of my 26.4 Gallon tank, lol. I was getting concerned, was a big time mistake by me, but the truck somehow pulled it off.
Rear gears are 3.73's and it's a FX2 with the 20's. Cruise was set at about 60-62mph, but construction and such lowered the average down to about 55mph.
(the actual fill-up was 99.3L if memory serves me right, just a touch worse than estimated)
