I switch to E85 four years ago and still use it
My bracket current car has two very small oil coolers for the radiator due to it being a blown methanol burning car that was towed all over at the race track except for the burn out and run before I bought it
It runs very consistently from early morning to late afternoons and cools down quickly, I have to drive it around a lot more than I would on gasoline to get the coolant and oil temps up in the morning
I do use the local pump E85 so your fuel deal will probably by be more consistent than my fuel supply
