1,200-2,200 rpm isn’t where the extra power is needed. When you need extra peak power you are giving it gas and it’s going to rev much past 2,200 rpm. E-85 will supply more power.

We tried the e-85 for a while, went back to regular gas, seemed like we were always needing fuel, didn't seem cost effective.
Supply more 'power' how? Your engine runs on 87 octane. Using 100 octane, should run the same, but maybe a little hard starting cold. I don't think you can use E85 in the EcoBoost.

Not 4th gens. Many 07-14’ 3rd gens are flex fuel capable. Previous to that and after that not available.

I'd go one step further and specify only 09-14 Expeditions/Navigators wereFlex Fuel capable. 06-08 5.4 3 valve were not. Suspect is related to the 06-08 being 300HP where 09-14 got bumped to 310.
Fun fact: first factory Flex Fuel vehicle was famous Ford Taurus in 1996.
Another fun fact, every gallon of gasoline I put in my Expedition, regardless of variety .... is Flex Fuel

Are you sure on that? You could be correct but I am pretty certain my neighbors 08 has the Flex Fuel badge on the back. Also you could order a F-150 5.4L with either E-10 or Flex Fuel capability in the 11th gen (04-08). Ford rates it (09) at 310 HP/ 365 lb ft on 87 octane gas and 320 horsepower/ 390 lb ft on E-85.

I live in the Midwest.
When fuel prices suddenly spike overnight (all stations in tandem), the local media runs (and reruns) their standard stories about how the fuel companies had to raise the prices.
One of the often-cited excuses is that the refineries are doing scheduled maintenance, thus the price increase.
I always wonder why my local Kroger store doesn’t raise prices when they do scheduled maintenance on the store?

Yeah no! Theres huge amounts of supply that are controlled.
The industry has found essentially a consumer's approved per se cost per gallon you'll notice the cost float around.
Also, Kroger's has a massive supplier network and is largely southern based aswell.

I've never used E85 but recently thought about running a tank of it. Even though the car is designed to run on it my concern is it's an 09, now suddenly throwing E85 in it will it cause sudden leaks or other issues?
I mainly want to run it as it's allegedly a good cleaning method. I know it's going to get about 20% less mileage but sometimes the fuel is more than 20% less expensive so it breaks even. Besides, not planning on running E85 on a regular basis.

I wasn't aware there was a flex-fuel option (3.5L, '18-'20).
E85 is gubermint subsidized - hence the artificially low price.
These days all fuel is e10 unless you can find/buy the ethanol free stuff (bu-cees carries it in lots of location).
From the '20 owners manual....
