gstallons Posted July 23, 2011 Share Posted July 23, 2011 The lead acts as a lubricant for the valve seating surface. A hokey-pokey way of lubrication, but it started back when the atmosphere was just something to breathe. You can purchase enough addatives to help replace what is now removed from fuels to where you can run vintage iron. BZZZT! Nice try, but unfortunately, incorrect. The removal of lead from fuel revealed a need for different valve seat material, but that was a by-product that had never been accounted for, not the reason lead was added to fuel. And by "lead," I'm talking about the octane booster tetra-ethyl lead [hence, the nickname "ethyl" for high octane gas, vs. "regular" for the standard grade.] And modern octane boosters don't work anywhere near as well as a shot of avgas 100LL ["Low Lead" here is a relative term: 100LL has much more TE-lead in it than any road-going version of gasoline ever had...] All of which is great for those of us w/ Guzzi's w/o a cat in the pipe. Thank you for your correction............. Link to comment
