I usually fill up when the gas light comes on (it comes on really early, so I have like 3.5 gal left in the tank). For the 13.5 gal I use, I get about 360 miles give or take 20-40 miles depending on weather/driving habits. I have a lift and 32" tires. I average about 25-26 mpg, but have gotten as low as 23 mpg when hauling TONS of stuff going about 75-80, and as high as 28 mpg. (all calculations done per fill up). Oh, I have 4.56 gears.
