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.

- In states that do not use E10 stickers on pump to identify ethanol was added, check the gas with an ethanol fuel test kit or quik-check solution

- Beware:  Your engine owner's manual and/or warranty may forbid use of E-10 gas. View Manufacturer warnings.

- Adding alcohol-based fuel additives, octane enhancers, etc. may decrease fuel efficiency even more.  View additive list.

There are many other measures you can take to improve your vehicle's mpg. 
Even something as simple as checking and changing filters frequently, to prevent fuel restriction, will improve your mpg.
(Filters will become dirty quicker when using E10, due to it's cleansing & solvent abilities).

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 Gas:
Fuel Efficiency/MPG
CORN FUELS...
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.

Ethanol Alcohol Fuel Test Kits

Consumers have not been properly educated on E10 and often are unaware of actions they must take to prevent problems (damage) from ethanol fuel blends and to maximize fuel efficciency.

A report published by the EPA titled Fuel Economy and Engine Performance, states,
"...oxygenates (ethanol) cause minimal reduction in mpg"...
And
"...many engine performance problems are due to factors other than gasoline and may be corrected by relatively simple consumer actions..."
And
"...fuel economy loss that can be attributed to the presence of oxygenates is 3%...".
See http://www.epa.gov/otaq/regs/fuels/ostp-3.pdf for complete report.

Fuel-testers Note: A larger engine in poor condition or with outdated emissions system should expect to have much greater than 3% drop in mpg.
