Duratech had an add that was my favorite. Couple of clods who were so deeply impressed by an engine running with the oil pan removed. The one even commented on how it was so good the oil pressure light didn't even come on. Think about that for a moment. On to slick-50. Dupont, the original patent holder on the chemical PTFE, trade name Teflon, attempted to stop the Slick-50 makers from using their PTFE because they knew it not only didn't work, but was bad in internal combustion engines. Dupont lost in court, so Slick-50 continues. PTFE absolutely will not adhere to an oily surface. It requires the same sort of metal prepping that paint requires. PTFE is the exact same substance that is used on Teflon coated skillets. Again, it absolutely cannot adhere to an oily surface. To cure, PTFE requires temperatures several hundred degrees higher then what an engine runs at. PTFE in a free floating form tends to clump and expand. Usually the oil filter catches it, but not always. It can clump up in an orifice, doing rather unpleasant things. So it can't stick to the metal in the engine, can't be cured on if it were to stick, clumps in the oil, and gets trapped out by the oil filter. Other then that...
