What fuel do you run in your EcoBoost pickup? (not HO)

I ran mostly 87 in my personal Ecoboost truck that I put over 80k on. I didn't see much of an improvement over 87 and saw better performance improvement from my 5 star tune.

I ran nothing but 87 on my company Ecoboost truck that I put over 130k on. My company has well over 150 Ecoboost F150s that are used as parts deliver and outside sales trucks, and we run nothing but 87 in all of them. Some tow heavy on a regular basis and some don't. We generally auction them off between 150k to 200k miles.
