E85? I don’t know what it goes for in Tennessee, but here in AZ it costs more than regular unleaded, and it contains less energy, meaning you get poorer mileage using E85. So you get to pay more to drive less. Yeah, that makes sense.
It’s about the same price as regular unleaded, at least in west Knoxville. Actually, it was more expensive to purchase E85 than unleaded after the huge drop-off (i.e. return to sanity) of gas prices back from the $5/gallon bloat for a week or two.
