Last week while in TN I bought 87 octane 100% gas. $2.44.9 a gal BTW.
I usually get around 11 ~ 11.5 MPG with the 10% corn stuff. I was getting 13.5 MPG. I was amazed!
Twice I filled up with the good stuff and results were consistent.
I THINK the truck felt peppier but that could have just been my joy at the MPG
