Coming out of 20yrs of diesel, into a 2015 ecoboost i was pleasently surprised at the power it had towing. I then went to my current 6.2. At first i had the same somewhat disappointed opinion too. But 10k miles later and having towed a bunch of different stuff i have come to really like the 6.2. It is not easy going from powertstroke to the 6.2 because i got so used to the low end turbo power. I dont have to buy another 6.2 but i want to. The 4.30 gears alone will make a big difference for the 6.2.

I think, now that we have a 2.7L EcoBoost F-150 in the family, that the GDI twin turbo gas engine can perform every bit as well as a full-fledged diesel. I think a 4.5L V8 EcoBoost would be a monster producing an easy 500HP and 700lb-ft.
The two areas where the diesel would still always win out are actual fuel economy and longevity. Fuel economy is simply a result of required boost, and the diesels don't need as much boost as often as the gas turbos. When they do, however, they suck down the fuel just as well. The diesel engines also tend to have engine components designed to run for a longer lifespan. There won't be a timing chain stretch or guide issue on an HD diesel. No DI fuel pump wearing down a cam lobe. Tougher cranks and generally tougher blocks, although the 27L is a partial CGI as well. However, I think a lot of people could be well served by an EcoBoost engine in the Super Duty. Honestly, the high-output Raptor V6 would be a pretty interesting Super Duty engine.

The Raptor version of the 3.5L would definitely be interesting in the F250.
The 3.5 is rated at 365/420. Going to a F250 gas just doesn't seem logical for my use. IF I were to go F250 it would have to be diesel to warrant the F250 IMO.
I pulled a 12k trailer full of rough sawn heart pine beams and the truck did fine. It wasn't a real long trip, probably 200 miles. Not sure what the new engines will do but hopefully the gas will go up with power.

I, too, came to appreciate the 6.2L. The 4.30 gears will help considerably as will the power bump and potential throttle recalibration. I think it is a great engine choice for the Super Duty if you want headache free operation and cheap maintenance.

I loved my 15 diesel however had a water in fuel scare that without going into to much detail ford really took care of me and made me a customer for life!! Just seems to be to much risk vs the reward for me in these newer diesels. God they are beast mode though!!!

Since WIF (like any other super rare diesel issue) already happened to you, you are the safest person to buy a new 6.7. Lightning striking twice and all... Don't fear the unicorn bud.

A gallon of gasoline contains approximately 114,000 BTU's, and a gallon of diesel contains approximately 139,000 BTU's......BTU's are what make horsepower!

Also, the fact is, a gallon of gasoline can not produce as much horsepower as a gallon of diesel fuel, no matter how you roll, simply because the energy is not there. Therefore, a 500 hp diesel will use less fuel than a 500 hp gasser.

You're right, the diesels do better (see EcoBoost 2.7L economy vs RAM EcoDiesel economy) but gas turbos have other advantages they are just beginning to exploit. Manufacturers are experimenting with mixed ignition strategies...such as compression ignition for gasoline engines at certain points.

Wow, 6.2's are awful, gutless, gas hogs.
On my my recent 1600 mile road trip with 8500lbs, scaled, through the gorge on i40 at the TN/NC line from Knoxville TN to the outer banks of NC I averaged over 9 mpg while towing, hand calculated, not the lie-o-meter. But the meter was very close as usual. The truck had just rolled 4K miles before we left. I got stuck in the right lane behind two big rigs before black mountain opened to 3 lanes and was down to 30 mph, the truck pulled itself back up to 60 no problem(5 over the posted speed limit) and I held it to the top. Oh, and I have 3.73's. My dad has the 4.30's, and I would recommend them, mainly because city mpg is a bit better, and it's faster, but the 3.73 is no dog. 4.30's are also nice for when you put the big tires on.

And to the one that says a gas 250 doesn't seem logical to them, this load is over payload in any f150.

There is also a member on here by the name of flatbed Ed, he has 323,000 miles on his 6.2 with no major issues. And obviously by his name and the miles, he uses his truck. Many with 200,000+.
