dont run e85. the 4.0 isnt mean to run on it.
Usually, they put more ethanol in the fuel in the winter. That, plus being colder out will make the truck get worse gas milage. I see about a 3mpg drop from summer to winter. Also, I warm up my truck in the winter so that also takes a toll on the milage.
