I've changed my driving habits a good bit so I think I will try different octanes again on the next couple of fill ups. By the way...Chevron Premium for me...from a month old station in my neighborhood.

Definitly NOT true I have found out. My truck is now averaging about 21.4 mpg on the way to work after switching back to the low octane 87. Lower octanes burn hotter. Higher octane is for high compression engines to eliminate pre-ignition which causes knocking that can damage these engines.
I will add a video for the non-believers HERE.
I set the cruise at 70 and put it in Sequential 6. Still doing more testing. Truck has about 870 miles on it now.
See ya'
