"  Repairman and small-business owner Rich Herder doesn&amp;#039;t mince words about the damage ethanol in gasoline is doing to the small engines in outdoor power equipment. &amp;quot;It&amp;#039;s the biggest disaster to hit gasoline in my lifetime,&amp;quot; Herder says. He owns McIntyre&amp;#039;s Locksmith &amp;amp;amp; Lawnmower, a service business in Westfield, N.J. Founded in 1898 to refurbish saddles, the business today repairs more than 5000 machines a year\u2014mostly pieces of outdoor power equipment, and many of them, according to Herder, damaged by the alcohol in today&amp;#039;s gasoline, known as E10 for the 10 percent of alcohol it contains.  Herder estimates that as much as 75 percent of that work is not due to normal wear and tear, but results from the use of ethanol, which can cause rust and carbon deposits inside the engine, dissolve plastic parts and more. And if repair shops like Herder&amp;#039;s are already busy, you have to wonder what will happen this summer when gas pumps begin dispensing E15 gasoline; the Environmental Protection Agency recently approved the fuel for cars built after the 2000 model year, but the fuel could hit small engines even harder than E10 does. But now, because of all that ethanol-based wear and tear, a nascent industry is starting up: Ethanol-free gas, distributed in cans for owners of small engines.  Why Now? Alcohol in gasoline is nothing new. PM first covered the topic in October 1937, when it reported on a plant in Atchison, Kan., that used corn, wheat or sugar syrup to make alcohol, which it combined with a small quantity of coal distillate to make a fuel called Agrol. But 1937 was long before the advent of today&amp;#039;s small, high-rpm engines. Lawn mowers and chain saws were in their infancy, and other products, such as string trimmers, didn&amp;#039;t even exist.  Deposits and corrosion aren&amp;#039;t the only reasons alcohol is hard on today&amp;#039;s small engines. The power plants are easily ruined by bad fuel because they lack the sophisticated computer-controlled ignition systems found in today&amp;#039;s cars and trucks. The alcohol can cause the fuel to ignite at the wrong time in the combustion sequence, ruining parts in the process. &amp;quot;The pistons are the first to go,&amp;quot; Herder says. &amp;quot;They look like they&amp;#039;ve been hit with a hammer.&amp;quot; Clearly the time for an alternative has come.  Boutique Fuel The phenomenon of fuel-related problems has become so severe that the niche market for specialized fuel is growing fast. Tidily packaged little metal cans containing ethanol-free gasoline were just an oddity a few years ago; now they&amp;#039;re sold in hardware stores and by power equipment dealers, and people are taking specialized fuel seriously. There are at least three brands to choose from: MotoMix, from outdoor power equipment manufacturer Stihl USA, SEF from VP Racing Fuels and Truefuel from TruSouth. Of the three, only Stihl relies on an outside-contract chemical manufacturer to make its boutique fuel: Johann Haltermann, Ltd., a company that makes, among other things, precisely blended fuel for testing vehicles. Stihl was likely the first outdoor power equipment company to enter the boutique fuel market when, more than 20 years ago, it was so concerned about fuel quality in Germany that it introduced packaged fuel for its equipment sold in Europe. The market for these fuels is still so new that there&amp;#039;s no generally recognized name for them. But regardless of whether you call this stuff\u2014boutique fuel, packaged fuel or canned gas\u2014it&amp;#039;s an end run around the gas pump. Sold as straight unleaded gasoline or blended with oil for high-rpm two-cycle engines in chain saws, blowers and string trimmers, it&amp;#039;s expensive stuff, costing anywhere from $5 to $8 per quart. Despite the high price, customers might be willing to pony up if it means seeing an engine or its components run for several trouble-free years rather than seeing the engine destroyed or damaged by ethanol\u2014after all, avoiding just one ruined engine might be worth the cost. An Ounce of Prevention What if you can&amp;#039;t find canned fuel, or don&amp;#039;t want to pay the premium? There are several other things you can do to protect your engine, Herder says. First, he recommends using a gasoline stabilizer. There are too many to list here, but among the most widely sold are Sta Bil, Star Tron, and Sea Foam. &amp;quot;It&amp;#039;s not that the guys who use those products have no problems,&amp;quot; Herder says, &amp;quot;but they definitely have fewer.&amp;quot; Also, buy as little gasoline as possible, so that you run through your gas supply more quickly rather than letting the gasoline sit around and chemically decompose\u2014a process that can start in as little as two weeks. Herder recommends that when you go to fill up the gas container you use for your outdoor power equipment, first top off your car\u2014that will flush any low-octane gas out of the hose. For small engines, always use the highest octane you can find, he says. Typically, that&amp;#039;s around 93 octane, though regionally you will find higher octane blends. Despite the fact that his business has seen something of a windfall because of alcohol-related engine damage, Herder is no fan of the fuel. &amp;quot;It&amp;#039;s driving the customers nuts,&amp;quot; he says, asking, in a bewildered voice, &amp;quot;Who do they think they&amp;#039;re helping by adding more alcohol to gas? What positive thing is this doing?&amp;quot; "^^<http://www.w3.org/2001/XMLSchema#string>
