The AFE in the dash was reading 31.6 and when I actually calculated it out it was 30.5 when I filled to the brim with 10.33 gallons. I figure I had about 1.5 gallons of actual ethanol left and added 3.1 more from the E30 making it about E40. By the time I drove the ten miles home the AFE was on 42.5 so if you guys are right, if I put straight E0 in it should get about 60 mpg. The E30 is priced 30 cents more than E85 and 30 cents less than E0 87 octane. E30 was $3.399.
Excuse me for the noob question. You have been running E85 in a 2012 focus without any problems?
