the studies show that MPG drops when using e10 and even more with e15 fuels. Some reporting drops up to 20% with e85.
go ahead and google, I am not going to be citing links

Greenhouse my a**, here is official government site


https://fueleconomy.gov/feg/ethanol.shtml


Ethanol contains about one-third less energy than gasoline. So, vehicles will typically go 3% to 4% fewer miles per gallon on E10 and 4% to 5% fewer on E15 than on 100% gasoline

Hahahaha, government website my ass. Does that website have scientific controlled real world testing on multiple real cars? No, it recites the relative energy content and the assumed correlation to fuel economy. There are other properties of fuel that impact how efficiently an engine can use it. Unfortunately oil companies are ripping the consumer off by using even lower quality base stock and pocketing most of the benefits of ethanol blended fuel. I think all E15 should be mandated to be 89 octane or better, if they started with 87 base E15 would be 90 or so I think. Higher octane allows many modern engines to tune themselves to run more efficiently.

Back when there was a blender tax credit most companies did a similar thing. Charging more for the ethanol blend than regular even though it was cheaper for them but it was higher octane so they charged more. In the midwest we have a convenience store chain called Casey’s, they were somewhat ethical and charged the same for 89 and 87. That tax credit went away with the reformulated fuel standard many years ago. There are no subsidies anymore the price is based on supply and demand.

Higher ethanol blends are great for making power (if tuned for it), but simply using a fuel with increased ethanol at the same price with the same octane rating as other fuels is a waste.

Also, ethanol is hygroscopic so the more you have in your fuel blend, the more likely you are to have moisture build-up if the vehicle sits for longer periods.

If fueling stations weren't so sparse, I'd definitely do E85. With a tune, you'd be making Type-S power ... and the hit in gas mileage would be a wash seeing as the price of E85 is much lower. With all comparisons being equal, right now, E85 would make far more power than even 93 while still being more economical than even 87.
