I NEVER use ethanol but a lot of people complain about its performance.
It should perform better, as long as it's under 20%. If they are using 50% or more, they need to make changes to their fuel system to allow for richer fuel air mixtures. The problem with that is fuel millage will go down, but performance will be fabulous.
That's why it's best to stick to ethanol blends under 20% And if you make the modifications to properly burn 50% or higher blends, you can't burn regular gas anymore. Combined with lower fuel millage, ethanol sucks in that regard.

I am glad to hear that some people in this country still have the option. In Minnesota all our gasoline has 10% ethanol, and last year they were thinking over raising it to 20% until they were told that a 20% blend would void the manufacturers warranty of many new cars.
