    Took my 6.4 from northern Indiana to south eastern Ohio this weekend. Mix of two lane and interstate driving. I did the math and hand calculations were within .2 of the evic! I was very happy with it

    Speed and wind are the two factor that influence good MPG well also load. What was your average speed?

    I've had similar numbers but only if I kept the MPH below 60

    On my way home from my mom's this past weekend I had to stop for fuel and reset the evic. When I got to a fuel station close to home it said my average was 17.3 mpg. That was running 73 in a 65 and 64 in a 55 with me and my son in the truck and a few hand tools in the bed and some power tools in the cab.....not too bad for a 7k lb brick with a 392ci V8!

    The truck is capable of 17s in certain cases. I normally sit solidly in the 11-13mpg range with 35s and 3.73s. Towing, I see anywhere from 9-11.5mpg.

    On a road trip from MA to NC, all around Asheville/Brevard for a week and then back with 4 people and 4 bikes off the back with gear under the cap we got 17.Xmpg for 3400 miles of the trip.......blew us away actually. We were not babying it either.....65-75mph

    It can do it, but it is like the sun and moon need to align and you have to sacrifice something to the Gods.......

    5-10 mph light variable wind, average speed 65mph. Keep it under 75 it does good. For the last 40 miles I had the cruise set on 84mph and it was starting to drink the fuel. I have 3:73 gears, crew cab short bed with loaded tool box and had a dog box in the back hauling a dog to get bred. I’m sure it was a little over 7,000lbs rolling
