E-85 detection for non E-85 cars and trucks, Specific Gravity?

Lately I have been seeing cars and trucks on the repair shop floor with overly rich running black spark plugs low power. And find out after major repair the car runs the same. Driveability diagnosis with only a P-0300 code can be difficult. I am looking for a test device for checking if the owner put the wrong fuel in there car. Most of the time the "owner says" My Wife drives that SUV? I don't know what she filled up with last...

Update:

I know what it is called I just want to be able to detect it and at what percentage. Non Flex Fuel cars run really poorly on anything greater than 20% Ethanol.

Update 2:

It appears that you can add a cap full of water to E-85 and it gets asorbed and the fluid turns clouldy. A simple test of Ethanol Alcohol fuels. Now just how much did that customer add to there tank?

Update 3:

I could not find any OTC tool for fuel checking?

    Sorry I have no answer for you at this point. Have you tried talking with the different vendors you use such as Snap On etc. JC whitney, or different diagnostic equipment companies. if you work for a dealer I know some of them have ways to ask the "know it all or expert tech guys" questions by phone or computer. Also how about the fuel companies they must have some way to test their own products.

    I am interested to know what you find.

    E-85 is just alcohol from corn, used to be called "Gasohol" perhaps the proportion in gasoline is greater now, but I don't think it would foul up plugs and would clear up when standard gasoline is used.

    The ECU adjust fuel mixtures anyway. Check with the make of vehicle for any TSBs relating to your issues.
