Flex Fuel E85
Anyone use E85 fuel in their super duty?
Just passed a gas station and saw it for $1.72 gallon. Regular 89 was $2.20 a gallon.

That won't be a large enough price difference to justify the drop in mpg. 22%, you need greater than 30% if I recall.
Edit - this says 28%.

Yes, the 89 is also wasting your money. Use what your manual specifies.
In general, E85 is only cost effective in corn-belt states.
