Ethanol has a higher octane but doesnt have the same amount of energy per gallon that gas does, therefore giving you less mpg. If you look at a window sticker for a car that is capable of running E85 you will see a different set of parameters for the two kinds of fuel.
The only alternative fuels I see having a future are hydrogen and biodiesel.
so do you guys notice a diff. between the gas and the 10% ethanol? i heard eathanol likes to eat rubber also
i remember emay saying it will take quite a while for the rubber components in the fuel system to break down, maybe 6mo to a year it won't show damage immediately but they will inevitably break down.Someone (Emay?) had some info on converting gasoline engines into E8, I also read a brief summary by an auto journalist in Canada about GM's trial fleet with E85 in Alberta or somewhere cold up there... aside from having to replace the entire fuel system with stainless steel, possibly the fuel tank and other pieces.
I don't know how long a fuel system not designed for ethanol would hold up to the stuff, but they've probably found a way to replace it at the factory if they're selling the vehicles new with long term warranties....
That's why they're looking into alternative bio sources to replace corn. Last article I read about it said people were hopeful algea could be used (what about farmers' industry lobby...) that produces substantially more ethanol with relatively no water input and doesn't require arable land.Not only is E85 less efficient compared to gasoline, but production is also less efficient. I read a study somewhere a while back that said if ALL of the available farmland (not just current farms, but all available land capable of growing crops) in the US were converted to growing corn and other crops for the production of E85, it wouldn't be enough to supply the US demand for fuel. Also, the production of ethanol itself uses a tremendous amount of energy and water,[...]
