BTW, ethanol in gasoline certainly is about pollution. Do a smog test with 100% gasoline and then switch to E85 and see which comes out better in HC's.
Speaking of confusing.
How can burning more gasoline, not enathanol, nor ethanol / gasoline blend, result in anything MORE pollution?
I don't know what you mean by burning more gasoline? If you burn 100% gasoline you have the most energy content. If you burn E10 you will have slightly less energy (as explained above) but it will be a cleaner fuel (air pollution wise) than straight gasoline and you will burn a less "amount" of "straight gasoline" because you will now be burning a % of alkie in it's place.
Look at it this way:
It takes fuel to clean the DPF in diesels. Somewhere around 1 to 2 gallons average/ tank of fuel. Some would say that is a waste of fuel. But what they don't get is the exhaust that comes out of the diesel pipe by using this tiny amount of fuel is now EXTREEMLY clean.
It took energy to clean the air that comes out of the pipe. Another way to look at it is this. It takes energy (electricity) to run your vacuum cleaner. So it takes energy to clean the carpets in your house.
Do you want to use a tiny bit of energy to have clean carpets? Or do you want to use no energy and have nasty carpets forever? Do you want to use a tiny bit of energy to clean the air that comes out of your tail pipe? Or do you want nasty air forever?
BTW, mpierce's figures are slightly off. E10 in a modern EFI engine typically burns about 3 to 4% more fuel than E0. Lets not miss the point of his great post though. It takes a very small amount of energy to have clean air.
Let me close by saying I'm no alkie fan. (Well, EverClear is pretty good) :) I personally think E85 is a VERY poor idea because "I" think it's negative energy. But, E10 is a great idea for air pollution because it works. How do I know it works? I have seen it and dealt with it first hand.
