i have tracked the fuel on my 2012 ram 2500 hemi, crew, 6.5ft, 4x4 since new (november 2012). so far i am at 12.12 mpg average over the winter being remote start happy. i hope I see over 14 average this summer having already averaged over 13 on a couple tanks when i don't have to do a bunch of running around. it seems the sweet spot is about 67mph with my 3.73 gears on the highway where it showes me about 16-17 mpg on the readout (always within .3mpg of my tracked true mileage). with 3.73 gears and .625 6th gear ratio it seems to bog alot if you go under 65 and ends up sucking down more fuel, over 70 the aero drag makes it start guzzling dino juice.
