BRZ Fuel Tank capacity = 13.2 Gallons
E85 = $2.65
Premium = $2.65 + $0.50 = $3.10
Premium Average MPG in City = 22 MPG
E85 Average MPG in City = 22 * (1 - 0.25) = 16.5 MPG
Premium Average MPG Hwy = 30 MPG
E85 Average MPG HWY = 30 * (1 - 0.25) = 22.5
---------------------------------------
Tank of Premium = 13.2 * 3.10 = $40.92
Tank of E85 = 13.2 * $2.65 = $34.98
---------------------------------------
Price Per City Mile Premium = $40.92/(13.2 * 22) = $0.14 Per Mile
Price Per City Mile E85 = $34.98/(13.2 * 16.5) = $0.16 Per Mile
Price Per Hwy Mile Premium = $40.92/(13.2 * 30) = $0.10 Per Mile
Price Per Hwy Mile E85 = $34.98/(13.2 * 22.5) = $0.12 Per Mile

So you may have to check your area for your price difference and you will fill up more often but in general the price difference between both seem to be pretty minimal.
based on national average the price difference was about $0.88
If the price difference is around that or greater the $0.90 you are getting virtually the same price per mile or better. I hope that helps.
