10%more Back on the fuel mileage issue, my EVIC keeps going up. Lately have not been doing even light towing. Near all the time I am showing 22-22.8 mpg on the EVIC. My fueling technique is to wait 30 seconds after "click-off" and do that again. Have never calculated 20 mpg yet. Now with the EVIC reading even higher I expect to see a real 20 mpg run if I can get a distance over 400 miles without towing.

Time will tell.

Yeah I watched the TFL video on the Ike Gauntlet on the 7.3. As my ‘16 gets closer and closer to 6/100,000 warranty powertrain expiration, that Ford is looking pretty good. Will be interesting to follow this motor over the next year for any reliability issues that may crop up.

Not sure why, theoretically we were expecting the HO to get a little worse mpg. It might be that the HO gets better mpg towing and so the lower mpg dd comes out in a wash. Not sure, just thinking out loud.
So what you have said so far is your dad had a 2017 and now has a 2019, those are the facts.

Yes I know many people that have had the internal struggle and swapped back and forth. The 4.10s they put in the gassers make them 'quick' feeling for a big gas truck. As long as youre empty or light. Put 10k+ back there and the true difference in power is startling.

For the hobby truck, a gas engine makes alot of sense. I hate to say it, but did yall see that 7.3 OHV gas V8 ford is bringing back. If I couldn't work on a diesel engine myself it would be alot harder choice for me too.

Mine evic is optimistic by 0.5 to 1 mpg on a consistent basis regardless of towing, bobtailing, 4wd, summer, stupid cold or ac use.

Can't comment on that comparison. What I pull and how my girlfriend uses her 6.4 is entirely different. As is the driving style.

What I can say is that initially my 6.7 got slightly worse mileage than the '14 6.4 I used to have, towing the same (light) trailers.
Also, I have no good numbers for running my 6.7 unloaded. The one time I bob tailed for any distance (some 850 miles, I think), the rear tank didn't get completely filled, which obviously skewed the numbers.

Sorry I can't be more specific, but it doesn't help that she doesn't keep a log book, so the 6.4's mileage is whatever the EVIC decides to call it. I have no idea what it really is.

Jimmy N. Thanks, but I wouldn't exactly call it patient. Very impatient is more like it.

Just last week I started on yet another painful break-in procedure, and now have 496 miles to endure before I can unleash that vehicle's full potential.
Still, to me it's the diff gears that really count, so suffering for 100 miles worth of slow poking and not exceeding 25-30 miles before cool down periods is worth it to me.

Noisy gears suck, and setting up new ones may not be hard work, but it's not fun work.

I guess thats the kind of restraint you have to have when these trucks get this expensive. I commend your patient right foot.

Heck, I hadn't even added the heavy flatbed yet. It's too hilly around here, I guess.
On a C&C I wouldn’t even expect it.
Problem is, You are too darn honest.
