Probably because the water test with a graduated tube was a lot easier,
cheaper and probably more accurate. When we first got the ethanol here, I was filling my plane from cans that I had for awhile before I noticed the ethanol sticker. (I always looked, too) I dumped 5 gallons into a partial tank before I checked just to make sure. It came up exactly 10%, which is what the pump label says (no more than 10%). I shook up the plane to mix the gas and took a sample. That came up as 3%. I siphoned it all into my car. Fortunately, I hadn't started the plane with it. mike "Tri-Pacer" wrote in message . .. The reagent appears to be methylrosaniline chloride. See U.S. Pat. 5,229,295 issued to Basil B. Travis of Lodi, CA. A colorimetric test for alcohols (any alcohol) comprises 0.1% gentian violet dye in mineral oil suspension which when shaken with fuel causes the fuel to become purple when there is at least 1% alcohol present. The purple color is proportional to the alcohol concentration in the range 1% to 5% where the percentage of alcohol may be estimated by the intensity of the purple color. snip As it is perhaps well known, gentian violet dye is chemically methylrosaniline chloride and has been used as both a bacteriological and histological stain ... Wow we're getting somewhere. I wonder why he quit packaging it and selling the stuff. Paul N1431A KPLU |

It was a very easy to test the fuel. They claim that their supplier no longer exists. I bought a bunch of the kits and have about 1/2 a vial of the chemical left. I sure would like to know what the reagent is that was used.

Don't tell Jim, he'll try to corner the market like the Hunt Bros... See if you'd held onto that silver for 25 years, you'd have something, besides silver... |

Call up Sportys and tell them you need an MSDS for it.
