Default 89 Octane

I mistakenly put 87 octane in my 05' Quad Cab Thunder Road. I noticed first that the truck was not pulling as hard. I secondly noticed teh MPG was lower with the 87 octane. I put 89 octane in my second fuel load, I definitely noticed a better MPG with the 89 octane. I wonder if i go up to premium if the 5.7l will like it better.
