I get around 300 miles per tank and thats driving normal with a few burn outs but noticed when I use Shell gas that I get 240 miles per tank. I tried this with my son's STX and had a similar result with the mileage. I used the highest octane for both the trucks. I seem to get the best mileage from using gas from Quick Trip, Valero stations and always use the high octane gas. Anyone had any of those results from using Shell gas?
