Fifteen(+?) years ago, there were only about 2000 to 4000 E0 sources, yet some stations were selling E0 for only pennies to 10cents more per gallon. Now that there are nearly 15,000 E0 sources, the price gap between E0 & E10, even at "well" priced E0 stations is wide.
Ah..... advanced tech used to make ethanol, that when only 10% of it is blended & diluted into gasoline, causes MPG to collapse to 8% to 5% BELOW that of standard 87 octane gasoline(E0). Advanced tech, to ya.
Because the sellers can charge that much more, and people still buy it. Being able to charge more for E0 is why more stations have bothered to make the investment to carry it.
Nah! You don't talk to E0 sellers. I've talked to many E0 sellers. They truly believe in E0 (as all sellers should). E0 sellers are proud of the E0 they sell..... & sell it DESPITE E0 not making a pile of cash for them.
I guess that you're lucky you're not going through Florida, because, by law you're not allowed to use NON-Ethanol gasoline in FL. It's only legal for Off-Road applications. With the E10, I can get MPG up into the 40's on a typical road trip. Yesterday, I took my 2020 Kia Soul LX (2.0L) IVT (intelligent variable transmission) out for a little jaunt of 127.2 miles, on mostly two lane state roads, and got 41.7 mpg according to the computer on the car. Gawd, I love this car!
Generally, car computer MPG readouts over-estimate 87 octane E10 MPG. The use of 87 octane ethanol-free gasoline(E0) tends to accurize car computer readouts AND at higher numbers. My last five 87 octane gasoline cars have greater MPG than 87 octane E10, by 8%, 8%, 7%-8%, 7%, & 5%, by using 87 octane E0.
That law was over-turned many years ago. Now, Florida has well over 900 E0 sources to legally use E0 on the highway.
