Same here right at 10 mpg to 11 mpg.

 

I have about 1800 miles on mine now. Every tank I have checked so far, the dashboard has been 0.3 MPG higher than the hand calculation. With such a small difference, I will just use the dashboard numbers. I have not reset trip one yet. Lifetime is 12.4 MPG so far. Yesterday I drove 100 miles or so on a 2 lane highway. MPG was 15.0 running 65 to 70 empty. Best run so far. See my signature for truck configuration.

 

Thanks for the info, but there's no signature (that I can see).

Regards,
Jim / crewzer

 

Not sure why my signature did not show up in my previous post, maybe because I sent it from my tablet ?

Anyway please see my signature this time !!
