I see sheetz has 88 gas with 15 percent E junk in it for 3.99 for this upcoming weekend only. I am pretty sure that’s the stuff I ran out west “one” time and only got half the mileage. So is my thinking wrong? If you fill up with 88 E15 it will take 1.5 fill ups to get the same distance with 87 E10 so you’re actually spending more. Am I correct in this thinking?
