After 22,850 miles my lifetime hand calculated MPG is 45.2 while driving primarily in Minnesota. This is without purchasing premium gas, fuel injector cleaner, a scan gauge, grill blockers, attaching angle irons to the bottom of the transmission or running with 51 PSI in the tires. My MPG is 1.7 MPG less than yours but I also spend less dollars/mile and this is achieved with driving techniques that are not dangerous/annoying to other motorists.
Unfortunately, many of your posts are a disservice to members of this forum who are looking for common sense help with their FFHs. Excellent MPG can be achieved relatively easily in a FFH without resorting to the nonsense you continue to advocate.
If you use EPA # you are only getting 4mpg better as to I'm getting 10mpg better than EPA#. BTW I use 50psi.
Some members come here looking for help with their FE problems and I give them options that have worked for me for 122K mi. I also drove 2014 FFH for month and did testing on it to prove my ideas worked for FFH also. I don't see you offering any solutions for FFH members with FE problems. IMO
