In my opinion, a lead substitute IS NOT NEEDED IN OUR OLD TRACTORS.
1) Lead can help to a small extent in providing lubrication and a "cushioning" when and where the valves mate into the seat and in theory lead can reduce the extent of the valves recession down into the seat BUTTTTTTTTTTTTTTT in these old low RPM tractors and especially when they arent used for longggggggggggggg hard use, I just dont envision the use or non use of a lead additive as causing much, if any, noticeable difference.......
2) Since our old tractors are NOT high compression, I just dont envision any pre ignition spark knock problem that would require any lead additive.
Im NOT a chemist or mechanical or materials scientist or metals engineer BUTTTTTTTT thats my story n Ima stickin to it lol This is an area we may get allllllllll sorts of OPINIONS and were all entitled to them right or wrong, including my own
