Good test Ed. Could you give a hint as to how much of an increase you might expect to see in that size sample of gasoline and about how much water the test should start with? Thanks

When you have water and gasoline in a jar, there will be a clear dividing line between the two fluids. This is made much more prominent when there's dye in the gasoline. If you put water in the tall, thin jar and mark the level, then add gasoline, put on the lid and shake it, then let it settle out, the water will separate from the gasoline. Alcohol will stay in solution (suspension?) in the gasoline as long as water is not present. But the alcohol prefers to be in solution with the water. So, this process lets the alcohol depart the gasoline and join the water. If there was alcohol in the gasoline when you start, then after the shaking and settling it will look like the amount of water increased (and the gasoline decreased). So, you know the gasoline was "contaminated" with alcohol. Note that some gas pumps have one hose they share with three grades of gasoline and some of their gasoline grades DO have alcohol. If that's so, then don't use the first bit out of the hose for this test. Put the first gallon or two in the car, then do the test. If it passes, then you can fill your gas cans for airplane use.

What do you mean by "if the water level goes up"? Do you mean the total liquid in the jar? Or, is there a clear dividing line between the gas and water that is actually higher than the original water? Or what?
