Whether I burn gasoline or E10, my truck burns 10 gallons of gasoline. Unfortunately when I use E10, I have to buy and pay for 11 gallons of fuel. If the gas mileage is reduced by the proportion of ethanol in the mix, then 100 percent ethanol shouldn't run at all. Someone should tell the Brazilians. <g>

This is a vast program based on faulty reasoning Interesting post, thanks for sharing. So this seems to be a problem created by an air-fuel system that wasn't designed to work with ethanol. Wouldn't the problem disappear, or at least be mitigated, if the air-fuel system was calibrated to not be fooled by ethanol? Derek

Alcohol is an "oxygenate" which on modern cars (with closed oxygen sensor fuel injection control) means that the computer is "fooled" into thinking that the mixture is too lean with 10% alcohol, therefore the computer enriches the system to "compensate" (using more fuel). More alcohol is also therefore ingested into the engine and it becomes a spiraling effect of enriching the mixture to some extent (in theory). Therefore, a measured 10% to 20% reduction in MPG with gasohol and a total waste of the ethanol. Is this necessary or a defect of the present system? Anyhow, if my choice is to pay Hugo Chavez or the House of Saud vs. ADM, I'd rather pay ADM.
