“Perhaps instead of fighting ASTM certification, GAMI would allow outside testing…”
From what I had heard, GAMI initially did try to get their fuel ASTM certified but apparently one of the ASTM members tried to effectively steal their fuel formula, so they backed out. I don’t know if this is true or just a false rumor, but it wouldn’t be the first time an “industry-consensus standards body” tried to do something like that. Industry consensus standards look great on paper, but they often end up just being protectionist cartels opposed to any outsiders that come in with actual competitive products.
