Any input
a 1:13 ratio of E85 to 91 will not create any issues for you. I run 4:10 in my car (and the last two B58 cars I've had) to achieve E30ish and have had zero negative experiences

note: I figure a full tank is about 14 gallons but I know that's off a little bit but not enough that it bothers me
