You plan on switching plugs to while your filling it up?

Like I said go to the bullet and read... In a lot of cases the mpg ain't gonna change unless you have your foot in it every stop light. The 2 or 3 mpg difference is gonna be offset by fuel cost and again just my opinion
I agree with BigSmokey.. It's more effort than it is worth to run both. E85 is about 25% cheaper here than premium, and you will use about 30% more fuel.
