That makes two of us who won't buy from an unsealed drum.

I know you deal with water contamination given Aviation gas. I remember the couple times I got to pilot a single engine plane when I was younger when I was considering getting my pilots license. I remember pulling a bit of fuel off the plane's wing and making sure that the fuel wasn't contaminated. (Or so I remember being told that's why we did that. Years ago, I could be wrong. Not gonna look it up). I don't care what they add to the fuel to help reduce its ability to pick up water, it still will. Removing water from substances that are miscible in it isn't always as easily done as it can be said. Or at least that's my personal experience. I've seen ethanol concentration drop as much as 15% in the lab based on results of gas chromatography. I will admit that this is lab grade pure Ethanol that was diluted with ddH20 and it may more readily absorb water due to its purity.

While you may be aware of them, fact is that most people who want to convert their performance vehicles over do not. If you approach it right, I don't have a problem with E85 in a performance application that sees primarily track time. But a daily driven performance car I just personally don't like the idea.
