Motorcycle Forum / General / Motorcycles / September 2008Gasohol Considered Harmful
A young guy on a Honda Silverwing MC about the same vintage as Geraldine pulled in behind me at the one filling station in town where you can buy gasoline instead of gasohol. I asked him what he thought of running gasohol through the Kehin carbs, and he said that's why he had taken the trouble to turn in there, the implication being he didn't think much of it. I guessing that the gasoline in Sheboygan County is oxygenated almost to the same degree as the gasohol. It all burns lean IMNSHO -- lots of stumbling under acceleration particularly when cold and lots of missing at the city-street speed limit of 25 mph in second gear, which is ameliorated by lugging down the engine in third. Gasoline just seems to burn a little better, but the effect could be all in my head. I'll tell you what cures the problems, though: Riding a day or two west.  Signature.. Be Seeing You, ..

Using E10 could cause some problems in hot weather due to increased vapor locking and in cold weather riding due to phase separation of the alcohol from the gasoline and the water held in solution by the alcohol may wind up in the bottom of your float bowl. Your carbs would be more prone to icing. The FAA doesn't like gasohol and neither does the Experimental Aircraft Association... http://www.eaa.org/news/2006/2006-11-01_faa.asp FAA Warns STC Holders Against Ethanol In Auto Fuel November 1, 2006 — The FAA has issued a Special Airworthiness Information Bulletin (SAIB), warning aircraft owners and operators with auto fuel supplemental type certificates to ensure the fuel they use does not contain alcohol (ethanol or methanol). The SAIB reinforces EAA's ongoing efforts to ensure availability of compliant autogas by heading off or modifying legislative attempts in several states to require ethanol in all gasolines sold. EAA, one of two primary sources of automobile gasoline STCs for general aviation aircraft, advocates that at the very least, states should exempt premium grade fuel from ethanol mandates to ensure a readily available and safe fuel supply for aircraft. The FAA cites numerous reasons that alcohol and airplanes do not mix. Alcohol: Adversely affects the volatility of auto gasoline, which could cause vapor lock. Is corrosive and not compatible with the rubber seals and other materials used in aircraft, which could lead to fuel system deterioration and malfunction. Is subject to phase separation, which happens when the fuel is cooled as an aircraft climbs to higher altitudes. When the alcohol separates from the gasoline, it may carry water that has been held in solution and that cannot be handled by the sediment bowl. Reduces the energy content of the fuel. Methanol has approximately 55 percent of the energy content of gasoline, ethanol 73 percent. More alcohol equals reduced range. (But E10 is 90% gasoline and 10% alcohol, so 0.90 + 0.73 = 0.973. Apparently your range or power output would only be reduced by 2.7%.) http://www.faa.gov/aircraft/safety/alerts/saib/media/CE-07-06.pdf has a water absorbtion test that indicates how much alcohol is present in gasohol of unknown composition... >> A young guy on a Honda Silverwing MC about the same vintage as >> Geraldine pulled in behind me at the one filling station in town where [quoted text clipped - 54 lines] >a water absorbtion test that indicates how much alcohol is present in >gasohol of unknown composition... Yeah - just what you said. Don't stop in traffic or vapor lock will kill it. Rust corrosion also a problem but slower. You don't ever want to keep a bike sitting there with gasohol in it if you aren't running it. Take gasahol in a calibrated cylinder (chemical supply shop or make one) pour in 50% fuel, top with water and shake - see where the meniscus is between the gas and water after shaking - that's the gasoline content. - old sport fisherman trick.

Or move where they don't put crap in the gas. ;^) I'm amazed at all the people who think gasahol is an answer. There is NO practical way to make enough. Not when they waste Natural Gas to make it or divert food crops for production. We'd be better off with one of the synth gas made from coal or biomass from a dump. I figured out the impracticality of gasahol back in the 90's. -- Keith >> A young guy on a Honda Silverwing MC about the same vintage as >> Geraldine pulled in behind me at the one filling station in town where [quoted text clipped - 18 lines] >gas made from coal or biomass from a dump. >I figured out the impracticality of gasahol back in the 90's. We had the crap in the 70's gas shortages. Didn't like it then and it is no better now. Rust out gas tanks and lines, runs up the cost of my Cheerios.
