Water mixes with alcohol. Alcohol mixes with gasoline. The water is "removed" when it is sucked into the engine along with the gasoline and alcohol, and goes out the exhaust as steam. Since it's mixed with the alcohol and gasoline now, the water goes through in small enough amounts that it does not cause problems. [Reply]   [No Email]

I think it's fine at 10% or less in equipment that is compatible with it. I do avoid using it in fuel that I mix for two-stroke engines. We used to buy a different kind of heet for our snowmobiles, but haven't done that for 30 years. [Reply]  [No Email]

Considering the octane, stablity of the fuel, even flash point, and so forth, many modern engines will become more efficient at that blend rate, and offer the best bang for the buck in fuel usage. That might seem counter intuitive to some, as ethanol has less BTU per gallon. But the deal is, it burns more efficiently _if_ the engine can be tuned to use that efficiency. Modern computers can monitor and use the good atributes of ethanol, and thus would do better with around a 20% blend. Unfortunately, it's not legal to sell a 20% blend in a common fuel pump, so few people get to see this, unless they do their own blending using an e85 pump and a calculator. I understand this does not apply to small engines or old carb engines, etc. --->Paul [Reply]  [No Email]
