I do not claim any Chemical Engineering knowledge but facts are facts. Radial engines like the M-14 and large displacement US types have certain critical differences from "flat" engines. The master rod and main bearing are plated with pure Silver and the plated with Lead to protect the Silver.
Oil Additives designed to scavenge lead from the engine are used in "flat" engines because they run on 100LL. These same additives can erode the lead plating on the main bearing and expose the Silver plating. Silver is highly reactive to additives in the oil and contaminants like acids that are byproducts of combustion.
When plating protection is reduced, the huge loads generate heat which then may result in sudden seizure. You know when that happens when pistons start flying out through the cowl or the spinning thing up front stops moving. At that point your day doesn't go as well as you wanted it to!
Many automotive oils contain wear additives that can harm radials, don't use them. Be careful what gets dumped into the oil. MMO has been around before WW-II and has been used in radial gas and oil ever since. Many engine builders use MMO to coat moving parts during installation. Even "flat" engine builders. MMO gets many of it's properties from the small molecular size that result from selective refining of base stocks rather than blending of exotic chemicals.
Just my opinion.

I never would have believed that 2 chloro benzene could be so effective but it apparently is.
