The use of ethanol in motor fuels is still vexing to me. It’s supposed to make cars run cleaner, but ethanol has half the btu’s of gasoline, only a govt could mandate higher mpg from the car manufacturers while mandating a fuel that has less energy. Add to that it takes 1.3 units of energy in to produce 1 unit of energy out in ethanol. Call me crazy, but that means its a net gain of emissions. Interestingly in the article, it mentions the repeal in 2019 of E15 use during summer, apparently it produces more ozone aka smog in the summer ??!! Wait what? It produces more smog, but it’s supposed to be a cleaner fuel… can’t make this stuff up.
The ethanol industry aka the farm bureau is always looking for more govt handouts, this started with FDR when farmers got paid to burn oranges and slaughter millions of pigs to drive the consumer prices up.. go figure. So now they want to increase the amount of ethanol used in fuels to create greater demand for their product..
Where I live 88 octane is non ethanol, there also 85 and 91 non ethanol. I blend 91 and 85 together in the correct amounts to get 86. All of the non ethanol fuels are clearly marked. The ethanol laced fuels, mainly 87, are clearly marked. There is also E85 here for the flex fuel cars that Ford and Chevy make. Again, way less btu’s in this fuel so way less mileage, and it’s not that much less that regular gas, doesn’t make any sense at all.
I did not know that it was illegal per fed law to use E15 in certain power sports or lawn equipment due to the damage it causes to those fuel systems. I can tell you that E10 has caused me several issues, lost a fuel pump regulator on my dirt bike, carburetors completely destroyed by this fuel as well.
Thanks for the post, it is enlightening information !
