More discussion on ethanol gas fuel efficiency, mpg...
Who reaps the profits of increased gasoline consumed, caused by the lower efficiency of E10 and E85?
Answers very widely, and this issue is widely debated. Gas suppliers receive tax credits and financial incentives (subsidy) for sale of E10 and E85 gas; But, most consumers do not notice a drop in pump sticker prices when a station switches over to ethanol enriched gas.
Sadly, consumers all to often incur additional costs beyond the price of gasoline when using E10.
Mechanical problems when using alcohol fuels are common, especially in older engines when switching from non-alcohol to alcohol gasoline. The release of years of accumulation of rust, sediment, and other material in your engine, will also be removed and released or dissolved or disintegrated from your engine and engine parts - Result is costly repairs from clogged filters, disintegration and drying of parts (especially rubber and plastic) and numerous other malfunction of motors caused by ethanol/alcohol.
Excess water, which ethanol will attract into fuel, can dramatically decrease mpg and engine performance. (Lean, water-diluted fuel).
- Service and maintain your engines to obtain the highest fuel efficiency.
- Where available, purchase conventional non-alcohol fuel.
QUOTE: "Gas prices are up, and so is the volume of advertising for "gas-saving" products. When gasoline prices rise, consumers often look for ways to improve fuel efficiency. Although there are practical steps you can take to increase gas mileage, the Federal Trade Commission (FTC) warns you to be wary of any gas-saving claims for automotive devices or oil and gas additives. Even for the few gas-saving products that have been found to work, the savings have been small..."

E10 & E85 attract water into gas and reduce fuel efficiency (mpg).
E10 gasoline usually lowers MPG by about 2 to 7 %.
* Many studies report E10 gas can decrease MPG as much as 20%!
* The actual reduction in mpg is dependent on your engine type, age, size, condition, fuel injected or carbureted, etc.
E10 gas blends always have lower energy and often drive fewer miles.
The EPA and ACE (ethanol.org) report a 2 to 3 % reduction in studies performed on newer, small engine cars in excellent condition.
A 2 to 3 % reduction in fuel economy = 1 mile/gallon fuel economy reduction in a car that averages 27 mpg.
A 4 to 6 % reduction in fuel economy = 2 miles/gallon fuel economy reduction in a car that averages 27 mpg.
E85 (85% ethanol) generates only about 75 percent as much power as a gallon of gasoline. That means that ethanol would have to be roughly 25-40 percent cheaper per gallon to be a bargain for consumers, which it is not true today.
The damage and negative effects alcohol gasoline can have on engines and parts is often more costly than the reduction in mpg.
