30% of 14.5 (14.5x.3) is 4.35 gallons of ethanol and 10.15 gallons of 93
Except that you want to put in 30% ethanol, not 30% E85.
Gasoline is usually 15-20% ethanol, E85 is obviously 85%ish ethanol.
So estimating 10 gallons of fuel. You'd want to add 8.5 gallons of 93 octane and 1.5 gallons of E85. This would give you an estimated 29.75% ethanol content. Or E30 fuel.
