Just completed my first full tank on the Silver Beast. First, the fuel mileage for a full size extended cab truck is outstanding, 19.9 mpg, something that my diesel F350 never reached in mixed city / highway driving. The truck is bone stock, no special hypermiling, just kept it at the speed limits and kept accelleration reasonable.
Also, the instument cluster has an average mpg meter. The mileage reported on this gage and the FE calculated by odometer / gas pump were the same.
Capitalism: The cream rises. Socialism: The scum rises.
2010 Ram 1500 Crew Cab 4x4 4.7L SOHC 2V V8 3.55 17" Wheels.
Ratings: 13/18 and 15 Combined. It had 2700 miles on it when I bought it.
It has never gotten less than 19 mpg on straight gas or 18 mpg on E10. Lifetime average is 19.5 mpg with a best of 21.5 mpg on Straight Gas.
Your truck is rated 16/21 18. I wouldnt be surprised if you average over 22+ MPG on straight gas or 21+ mpg on E10 once its broken in.
