not much but technically yes.. I'll use the 2:1 ratio from above, and today's Actual Gas prices from the station at which I work.(and Yes, we only get regular and premium, the Mid is blended by the dispenser) We (and most stations in our area) have a 30Â¢ Spread between grades, and it's all E10. as of 2pm today, Reg:$2.959 Mid:$3.259 Prem:$3.559 (don't forget gas prices always end with 9/10ths of a cent) so on a 15gal tank(makes the math a bit easier), you'd need 5 gal of Premium (93), and 10 gal Regular (87) 5*3.559=17.795 10*2.959=29.590 29.590+17.795=47.385 vs 15*3.259=48.885 48.885-47.385=1.50 1.50/15=.10 so in that scenario, you'd save $1.50 overall, or 10Â¢/Gal.
