Benefits
- Ethanol is domestically produced and allows us to reduce our use of imported petroleum
- Ethanol emits less carbon monoxide than gasoline
- Adding oxygenates like ethanol to gasoline reduces carbon monoxide emissions
- Ethanol production supports U.S. farmers and creates jobs
Performance
All auto manufacturers approve the use of low-level ethanol blends. Ethanol blends (10% or less) are successfully used in all types of vehicles and engines that require gasoline. From a consumer perspective, there is no noticeable difference in vehicle performance when low-level ethanol blends are used. Because there is a slight difference in the energy content of ethanol and gasoline, there may be a slight reduction in vehicle fuel economy when using ethanol.
Availability
Fuel ethanol blends are sold in every state, and ethanol blends make up nearly 100% of the gasoline sold in carbon monoxide and ozone nonattainment areas during certain months of the year.
Cost
Although ethanol is more expensive to produce than gasoline, federal tax incentives reduce the price to a competitive level. Ethanol prices tend to vary regionally due to availability and promotional efforts by retailers.

they are not sold at special pumps... you can't pull up to a gas station and go "hmm, I wonder if I want ethanol or not"
it's something that is added into the gas automatically at certain times of the year, etc.
but hey, what do I know... it's not like I live in the US or not

Thanks Saxman for pointing it out
Been trying to point out that fuel in the states are blended with E10 I think I read it somewhere that its blend all the time now in all major cities and other small places are blend like 270day of the year, so I guess the other 95days is good fuel day lol , the main thing I am saying is Ethanol needs to burn more to create the same energy. E10 has a higher vapor pressure than pure fuel, which gives the fuel a higher volatility. This increased volatility can cause higher evaporative emissions of light hydrocarbon from the fuel. It is this Higher vapor pressure which cause problems through fuel system components, although this is expected to decrease as fuel systems continue to meet new standards for evaporative emissions.

Congrats on assuming I've lived here all my life and never travel out of state.

I think for someone that lives in the US would know more than someone living in Thailand.
EuroAccord13, I think it will soon be about Aus and Jap fuel soon lol. 
not going to reply anymore I give up.

Ethanol content does not only vary from state to state but can even change in larger cities vs. state wide - I live between Detroit and Chicago and we get a much lower percentage blend year round compared to the bigger cities.
The EPA don't ya know
