Eli5 Ethanol added to gasoline

1.45K views

Almost every station I go to has ethanol (up to 10%) added to gas. For a long time I had the option in my area to buy non ethanol gas but now it’s harder to find.

If a gallon of ethanol gets less mileage per volume than gasoline, then how is it better for the environment if I have to fill that much sooner on gas because the ethanol component lowers my tank range?

Ethanol is also a cheap way for manufacturers to increase octane rating of lower quality gasoline.

It’s a win-win for the producer and a lose-lose for the customer. And it does little for the environment, especially if you consider the entire process from production to use.

Ethanol causes many long term issues, especially with small engines from lawnmowers to outboards.
