[QUOTE="mercurycrest, post: 27626, member: 64"] Here's a tidbit to chew on.... I seized my 1938 A Comet idling 1/2 hour, in a line of traffic on a hot day, two up, a couple of months ago. I was useing "Diesel rated" 10-40 mobiloil, and had .0065 piston clearance. When I took it apart, the underside of the piston was clean/clear but very sticky to the touch, almost like some kind of invisible glue was on it. Yes, I was using 10 or 15% ethanol, that's what we have here. Was it the oil or the ethanol affecting the oil? Out in the shed, I've found at least four cases of left over Castrol R from my misspent youth, if I can figure out how to completly seal the engine from the primary, you already now my "Plan B. So my question is: Will Bean Oil overcome Ethanol? Cheers, John [/QUOTE]
