I did ask that if this fuel is as good as the existing one (UL91) then what's the problem?
I have heard that posters have issues with the tone/content of the article or the characters involved etc. This fuel can be used as a direct replacement for an existing fuel without any need to modify the engine. As others have said, synthetic fuels have been around for a long time, even longer than most folks on this forum! There seems to be an emotional backlash against it, but no constructive objections.
