Was in a junkyard in South Pa.in the mid 70's getin parts for my 53 and saw a group of guys workin on an old 40's Plymoth. Watcht them for a bit. They got that car runnin. So I went over to find out how they did it. Marvel Mystery oil in the gas and the crank case with the old oil. They hand cranked it first with MMO in the cylenders first. Been sold on the stuff ever since. Slick 50, used it in my 98 S10 blazer. 174000 miles later still runs great. Dosn't burn or leak oil. Does anyone know where to get Slik 50 I can't find it anymore? I used to inject water in my intake,it cleand and raised my compresson on my 292. MMO great stuff.
