Commodity price of Pure Ethanol is now $1.80 per gallon. Commodity price of Pure Gasoline (not RBOB) is $2.01 per gallon. The difference in price is $0.21 or 21 cents per gallon.Oddly, the E0 87 at the Exxon convenience store near me was only .02 more than the E10 -- $2.49 vs. $2.47. Then I get .06/gal. off for using my Exxon card.
A 10% ethanol blended gasoline is about 2.1 cents per gallon lower cost to the gas station than a pure gasoline.
The Exxon convenience store is making the same sales profit margin on E0 as they are on E10.
They don't care which gasoline blend (E0 or E10) you buy.
They just want you to buy something in the convenience store.
