Why or why not?

I'm assuming the EPA numbers are with premium gas anyway. What mpg are you getting at highway speeds?Still burning through my first tankful that the dealer put in it. I’m sure it’s 87 octane.
I intend to use 93 octane on my next fill up to see how the mileage and performance differs. Mileage has been borderline atrocious so far, but I’ve been doing a lot of idling and giving into the urge of “opening it up” on more than a few occasions. On the flip side, performance is in-freaking-credible!
As long as I can afford it thereafter, I’ll run 93 in my truck as consistently as possible. I just like the extra power, and I’ve always thought it burns a bit cleaner. I’ve got the 3.5L EcoBoost for reference.

Good to know. I'm assuming the 93 is better for the longevity of the engine too so there's that to consider as wellI have about 3500 miles on my 3.5 EB and most of it has been 87 octane. But, a few weeks ago was filling up at Costco and we had a day trip planned for the next day so I filled with 93. I got about 1.5 mpg (20 mpg for the tank) better on that tank so I filled the next tank with 93 as well for my regular mixed driving. Same thing, about 1.5 mpg better. last tank I filled up with 87 and so far has been back down to about 17-18 but lots of short trips on this one. It’s impossible to really do a side by side comparison on MPG but it does seem to get about 8-10% better mpg with the 93. Around her the 93 is more than 10% increase from 87 so not really more economical. But, with 93 in sport mode it does seem to have a little more punch.
The trucks computer takes a while to start to get the benifits from 93. I’ve heard a couple tank fills before it starts adapting to it according to other threads with this same topic.Still burning through my first tankful that the dealer put in it. I’m sure it’s 87 octane.

Do you know if the 93 had the same % of ethanol as the 83 or was it possibly a higher % of gas?I have about 3500 miles on my 3.5 EB and most of it has been 87 octane.

I noticed on my recently generated window sticker that the driving range with the 5.0 is 742 miles with gasoline, compared to 519 miles with ethanol. I thought that was interesting.Why or why not?
