At lunch I'll go drive by the Valero and see what the price of 93 is compared to e85. Last I checked it was less than $1.00 difference.
So I never got those prices.. I did today..

Valero @ 1604/Culebra

93 oct 3.44/gallon
E85 3.04/gallon

Assume you're getting 20 mpg over 14 gallons on 93 octane = 280 miles
28% less fuel economy on the e85 is 14.4 so 14.4*14=201.6

Your results may vary, but this is just to give you an idea.
