Non- Ethanol gas observation

Well I’m glad I posted my observations. I thought it was more the lack of ethanol than the fact it was premium that was making a difference. This makes it easy for me to start using premium from my regular gas station all the time now.
One other observation - as I said I’ve been doing this once a year for many years. With my previous ‘09 FX4 w/5.4l I never noticed any difference. But today is was obvious. My typical 70 mile round trip to town is nothing but hills and bends on a 55mph road. My old 5.4 would constantly be shifting between 6th and 5th the entire way. I would bet it would happen at least 30 times in the round trip. There was no way to lock out gears like my new-to-me Lariat. Even without locking out 6th this truck behaves much more nicely. And today it acted even better holding on to 6th all that much longer.
Thanks everyone for chiming in! Premium it is for me!
rngtntl - my choice for my small engines is non-ethanol fuel. It just so happens that the only non-ethanol available happens to be premium. I am active in a tractor forum where we talk a lot about small engine equipment also. The consensus is that using and storing non-ethanol fuel in carbureted small engines proves to be worth it.

Yes, I know that. But up until 3 months ago my ‘09 FX4 had no such thing. It drove me nuts down shifting and up shifting all the way to town.
This is one on the many new features I have on my new-to-me ‘15. This one is pretty behaved even without locking out 6th - seems it will hold 5th quite nicely on its own. But on a couple certain hills I lock it out myself and am very happy that I now have that option.

Boost with high octane
I'm new to the 3.5L eco and the forum for that matter. I see a lot of discussion and both good and mis information on ethanol vs high octane vs mileage.
In my mind, high octane fuels should allow higher boosts=more compression. I have a boost gauge in my 7.3 but haven't seen much about that on an ecoboost.
Has anyone measured actual boost pressure differences on high octane vs 87 fuels? Is there an easy aftermarket A pillar add on for the F150?
Thanks.

Have not read entire thread, but, how does one know if its really ethanol free?
No state out there is testing for this like they do pumped volumes of gasoline.
I've tried it with no differences observed.
I also have stored ethanol-blend gasoline in clear containers (test) for one yr with and without preservative. And it takes almost an entire year before any visible suspended solids begin to form. Preservative Stabil use made no difference.
Maybe I'll post pics someday.

I have a 2016 2.7. My last fill was with premium in my 36 gallon tank. I have about 24k on the truck. I am getting 2-3 mpg better on premium over the 87 I have been burning. I average about 22 mpg on my trip from Vancouver, WA to Ocean Park, WA. On premium, I have made 2 round trips and I am at 25 mpg according to the trip computer. I paid about a 10% increase for the premium gas and I seem to be getting it back in increased gas mileage.

I find this hard to believe. I very much doubt you can get 20 plus hp and 40 plus torque going from regular unleaded to premium. That is a very big difference.
