Pull up to just about any gas station pump in America and you’ll see a sticker noting that the gas in that pump contains ethanol. It’s all around you, but most people don’t know much about ethanol.
What’s it doing to your car, and why’s it there in the first place. Aah, now that’s a good story.
What is fuel ethanol?
Ethanol is alcohol. It’s the same stuff that’s in vodka and every other alcoholic drink, and it’s made the same way – by fermenting corn or other biomass. But when it’s used for fuel purposes, the refineries put some extra chemicals in it to make it poisonous and unfit for human consumption, then they mix it with gasoline. In case it’s not obvious, you really don’t want to consider fuel ethanol as an alternative to your favorite cocktail. Heck, if you’re bringing cocktails to the gas station, you’ve got bigger issues. Drive responsibly and all that. but we digress.
