The fight over E15 is not over yet

The Environmental Protection Agency has given the approval for retailers to sell 15% ethanol blended fuel. The fuel we purchase at most gas stations around the country today already has 10% ethanol mixed in. The EPA and other supporters of the plan have wanted to add an additional 5% ethanol to the fuel mix for cars built after 2001.
"Today, the last significant federal hurdle has been cleared to allow consumers to buy fuel containing up to 15 percent ethanol (E15)," said Agriculture Secretary Tom Vilsack. "This gets us one step closer to giving the American consumer a real choice at the pump. The public has a right to choose between imported oil and home-grown energy and today’s action by the Environmental Protection Agency (EPA) advances that goal."
The goal of the plan is to help reduce the dependence on foreign oil by using ethanol derived from corn.
“In the eyes of the federal government, E15 is a legal fuel for sale to cars, pickups, and SUVs made since 2001,” said RFA President and CEO Bob Dinneen. “With all i’s dotted and t’s crossed as far as EPA is concerned, our undivided focus will turn to addressing state regulatory issues, identifying retailers wishing to offer E15, and paving the way to greater use of domestically produced ethanol."
There are still other issues that have to be overcome before E15 makes it to pumps. These issues include pending litigation and threats from Washington. The U.S. House of Representatives has previously threatened to block the EPA's plans to force E15 sales at stations around the country. Many still argue that the use of E15 could cause millions of dollars in damage to engines in vehicles around the country.
One of the organizations opposing the rollout of E15 is the Outdoor Power Equipment Institute or OPEI. According to OPEI, government tests show that E15 is harmful to outdoor power equipment, boats, marine engines, and other non-road engine products. Adding an additional option at the pump could confuse consumers leading to misfueling and damage of engines according to OPEI.
"For the first time in American history, fuel used for some automobiles may no longer safe for any non-road products. It may, in fact, destroy or damage generators, chain saws, utility vehicles, lawn mowers, boats and marine engines, snowmobiles, motorcycles, ATVs, and more," says Kris Kiser, President and CEO of the Outdoor Power Equipment Institute, one of the industry groups who have been sending warnings to the federal government about E15.
Keiser added, "[The] EPA purports to educate tens of millions of Americans using hundreds of millions of engine products, asserting it will educate these users with a 3 inch by 3 inch pump label. It's frighteningly inadequate."
Some major automakers also argue E15 could harm engines in cars and trucks as well.

So it's bad for 2-stroke motor

I understand it can be bad for 2 stroke motors, but 4 stroke? Is it because some 4 stroke motors are less lubricated than some others?

It's because ethanol is more corrosive on seals and gaskets, requires different fuel/air ratios and flow rates for proper combustion, and it breaks down into water over time to clog up occasional use items (snowblowers, mowers, weedwackers).

Ethanol does NOT break down into water, dunce. It cannot do that. Guess you skipped your high school chemistry class, eh?

The water problem with ethanol is that it attracts and bonds with water much more readily than pure gasoline does. That's the problem, not ethanol breaking down into water.

Who teaches you kids these days?

Yeah, that's a pretty hilarious error. Oh the educational system.

As for ethanol, it gets worst. Not only does it attract a high degree of moisture unlike other alcohols such as isopropanol or menthol, or gasoline, but also liquid ethanol always has a trace amount of dissolved acetic acid in it. Anyone care to guess what happens when all that ethanol attracted water interacts with the acetic acid?

That's why the gas line on my old lawn mower gradually desolved from the inside out. Hate to see this happen on a car. (wonder how much of an increase in car fires we will see)

It has to do with seals and other "rubber" bits in places like fuel pumps and carburetors -- and the fact that with more alcohol you need more fuel for a given amount of air, which your carburetor or fuel injection system may not be able to compensate; you will definitely get worse mileage from a gallon of E15. The DOT says their tests show no significant performance loss, but their tests do not contradict the auto makers, who report not significant performance loss but rather significant economy loss and significant engine life loss. Apples and Oranges.
