    Went to farm yesterday and decide to hand jam my mpg. 320mi @75-80mph mostly hills, some driving around the farm and quite a bit of idling “it’s hot and my truck was cool” lol. Anyways evic says 12.7 average. My hand cal was wait for it........12.6:gr_grin: I’ll try it again but I was glad it was that close. I don’t worry about mpg but I was curious

    That's pretty close. I've been hand calculating mine since day 1 (just for the fun of it) and mine is never closer the 1mpg high and up to almost 4 worst case.

    We returned Monday from a 3500 mile trip EVIC said 18.9. Hand calc(fuelly) was 15.7.

    I had been checking mine for a while and it was within +- 1 mpg.

    Hot damn, that is a huge difference. Usually when mine says 18.9, I am a little over 17 mpg.

    Yeah, 1mpg +/- is about the delta I see if I bother......maybe 0.8 one time and like 1.3 another but I also rarely do back to back full tanks to hand calc.

    Wether or not mine is accurate seems to be speed dependent. I’ve had trips where I was around 65mph most of the time be really accurate. On this trip most of the highway speed limits were 75/80/85. That seems to make it a bigger liar.

    Looking at the last 23 fill-ups, you can tell that mine is consistently off.
