As I understand it, water will sometimes stay suspended in gasoline. Normally, though, the water separates out to the bottom of the container showing a distinct surface between it and the gasoline.
Obviously, since they sell it that way, alcohol will stay suspended in gasoline. But, when water and alcohol mix in the gasoline, the alcohol will come out of the gas/alcohol suspension and mix with the water. As far as I know, the alcohol is distributed evenly throughout the water/alcohol mix. Water/alcohol is, I think, a solution, not a suspension. (A solution likes it that way, a suspension just needs an excuse to separate.) If you mix one inch of water with 10 more inches of gasohol in a tube, shake it, it will _look_ like you now have two inches of clear liquid. (10% of the gasohol is alcohol = 1" in the tube.) If your engine gets a slug of water, it will pump it through as long as the prop keeps turning -- but no power is being produced. You might get carb icing for all I know. If the engine is windmilling, the cylinders pump air and, presumably, suck liquid out of the carburetor jets. The common question is: do you contact the ground before the water is pumped out and the engine develops power again? If you have gas line antifreeze in your tank, the gas and water mix, separate and pass through the engine, hopefully continuing to produce power in the process. This works fine in cars. To the best of my knowledge, gas line antifreeze is NOT authorized in aircraft. It certainly attacks sloshing compound inside the tanks and makes a suspension of slush flakes and dirty gas. Perhaps someone knows if it also attacks other fuel system components. After my forced landing from gas line icing, I used HEET some when I was suspicious of water accumulation or contamination. I eventually stopped because of the sloshing compound issue. I've wondered if I could arrange a pump to push a bottle of HEET into the nose tank if the engine stops the next time I fly below zero. Probably won't mess with the HEET injection idea but that stuff sure cleans out gas line ice FAST! [EMAIL PROTECTED] wrote: > > I'm confused (something everyone on the "other" list is well aware of).
