One and ONLY gas mileage thread please

Dashboard still says 10.8 on my 6.2L 2011 raptor crew with 37's and top perch running 91 octane tune by Henessey and Volant intake.

does using 37 inch tires underestimate both mph and mpg?

Must say I don't know much about the tunes available for the Raptor, but don't they offer an adjustment for different tire diameters?

After picking up my Tux black Raptor SCREW this last Friday, I've finally started my journey back to SoCal. I'm near Amarillo, Tx on I-40 W. I'm doing 80mph with the cruise set, slight head wind. I'm getting 12.6 avg mpg. 2 total persons in the vehicle with just a few extra bags. I hope it improves.

Don't go 80 and it will 55-65 will get you best MPG

I would, but going 55-65mph on I-40 when everyone else is running 80mph would be a bit hazardous, and I'd like to get back to Cali sometime this week.

don't use cruise control for the first 1000 miles and be sure to vary your speed. if you don't do this it may only run good at 80mph. this is in the manual. and the way I have broke in all my vehicles . I just drove back from northern Cal. and the raptor wants to go 80 real bad.

I get around 16 mpg on the freeway if I can keep it around 70 or under. I average 7.6 around town.

Made it to Albaquerque, NM. Now reads 12.8mpg. It's getting better. 1,200 miles on her.

I get 11mpg around town in San Diego. 8mpg when towing the 5000lb. travel trailer.
