The owner's manual for my 2014 F150 Ecoboost engine says to use 87 octane or above at all time, including in the mountain areas that may have as low as 85 octane.
My owner's manual also says 87 octane is good for my Ecoboost, but further says that premium 92+ octane is probably best for the engine, when pulling a trailer, and especially when in the mountains.
It actually says:
3.5L V6 EcoBoost Engine
Regular unleaded gasoline with a pump (R+M)/2 octane rating of 87 is recommended. Some stations offer fuels posted as Regular with an octane rating below 87, particularly in high altitude areas. Fuels with octane levels below 87 are not recommended.
Premium fuel will provide improved performance and is recommended for severe duty usage such as trailer tow.

You will not find the reduction of "regular" grade from 87 to 85 octane until you get to higher altitudes, approaching Front Range of the Rocky Mountains.
What you will find in the Midwest, particularly the Corn Belt, is wide availability of E-85 at reduced prices. If you are concerned about anti-knock properties and your vehicle is flex-fuel, you can get higher octane properties (typically low 100s) by going to E-85, at some cost in fuel consumption.

Thank you for any help you can provide.

Probably fine with 85... however I use the next higher grade as my owner's manual says 87 minimum.
