Mercury No. 6 mystery. I have a reprint of Bowden's "Diesel Model Engines" (1951) where he mentions a fuel called Mercury No. 6. (on page 98) It was a NON-ETHER fuel composed of 6 components that, according to Bowden, ran engines quite well. He mentions that all 6 components were necessary or the fuel would not work.

Does anyone have any idea what was in this mysterious "Mercury No. 6?"
