One of the best things that ever happened to engines was the elimination of lead in the gasoline.
Before the introduction of catalytic converters, I worked in a dealership in the heave mechanical department. Most of the work was various engine repairs, transmissions, clutches, rears, brakes, and enything that might get the boys' hands dirty in the ''tune-up'' department.
One of the things that I observed was that engines that had failed for one reason or another had gobs of gray sticky gook in all of the little corners and crevices of the engine. There would be gobs of it in the oil pan. It was a big pain in the butt to clean up.
With the introduction of unleaded gas and catalytic converters, I observed that major engine repairs became less frequent. Those that did require repairs were so much cleaner inside. No more pockets of gray gook all over! Could it be that the lead was actually harming engines? Well, that is MY opinion anyways.
Over the years, I have used unleaded gas in many older engines. I never had any issues caused by the absence of lead in the gas. Personally, I think that the whole objection to removing lead from the gas because of the valve seats was just an excuse and nothing more.
What to do with the lead substitute? My vote is to just get rid of it.
