Does biofuel with 10% ethenol get the same gas mileage as regulare unleaded fuel?
I filled up with it once feeling good about my descicion. The lady at the station said that an average American using only unleaded biofuel would save a barrel and a half of oil per year, but it seemed like I may not have had as good of gas mileage, which means I’d have to fill up more often, counteracting the saving of oil. Can anyone give me any information on this?

yes
I think you better learn about BTU or British thermal unit. That is to say that everything that burn’s has a rating and it is all about how hot it is when it burns and at what rate it burn’s. So the less there is in something that is burnt the less power, heat or energy it give’s off. Gas has certain ingreadients like sulpher, benzine and other things. Well to get to the point ethenol has less to burn so less energy so you need more of it compaired to gas to get somewhere. The oil companys have lied again! Enjoy! Its only going to get worst. You need it, I need it, so let’s all bend over and take it where they want to stick it to us!
Non-political answer:
The energy content of ethanol is less than the energy content of a like volume of gasoline. Therefore, your engine needs more of it to develop the same power.
Biofuels are more costly right now than fossil fuels, so there’s no economic advantage to switching. The advantage comes from the fact that by using less fossil fuel, the USA becomes less dependent on foreign governments for our energy needs. It’s unlikely we will ever become 100% free of fossil fuels, but every little bit helps. And as more biofuel plants are built, the costs will eventually come down.
Ethanol gets less mileage than pure gasoline. Ethanol takes a lot of energy to make. Ethanol is made from corn, which takes a lot of energy to grow, such as fuel for tractors and energy for running the farms that produce it. In reality, it probably takes more petroleum to make and use ethanol than it saves. You could save more than a barrel and a half of oil a year by changing your driving habits, and in the process you can cut our dependence on foreign oil.
