Was at a Racetrack fuel station in Florida and filling up with regular 87
The third handle is orange, 88 octane and is 15% ethanol.
I would expect the E15 to cost less, not more.
Your problem is Florida,
E15 should be cheaper by at least 5cents or you don’t buy it.
My guess is your e85 is probably more than rug too while up here you save a buck.
Here in Wisconsin there is one particular station that carries e15 and it’s usually 15 cents + a gallon cheaper than any other stations rug.
My guess is your station figureS they can get someone stupid to think higher octane higher cost.
Around here something equally confusing is when normal e10 “mid grade” 88 octane is 40 cents a gallon more than rug. I honestly don’t know why a station would even offer 88 e10 as a premium mid grade but many do for some reason, not even worth using for even a penny more.
