My auto fuel STC does NOT allow fuel containing alcohol. Some aircraft fuel system components may not be able to tolerate the alcohol. There may be other reasons. I think there're some real reasons and it's not just the certification testing for the STC not wanting to bother.
Testing for alcohol is pretty easy. I get a tall, thin olive jar. When going to the gas station, I put an inch or so of water in the jar. Then I mark the water level carefully with a marker. Next, I fill the jar mostly full with fuel, shake it and see if the apparent "water" level has changed. Alcohol will stay suspended in gasoline unless there's water present. If water (the stuff I put in the jar) is present, the alcohol comes out of the gas to dissolve in the water. Since water/alcohol just looks like water, if the apparent "water" level has gone up, I know that batch of gasoline has measurable amounts of alcohol. Larry wrote: > > Contaminated Av or Auto gas?
