Rcpilot,
90 % damage to an engine occurs as a result of starting friction ( Taking the assumption that the engine is not run lean or overheated by over proping) when the engine is not wet with fuel.
I wish we had a lube for R/c engines which had polarized molecules to reduce this wear.

The engine are allready overlubricated (between 15% and 33%) after the engine are primed and very very very little to damage the engine while starting the engine.. I has many modelengines from 1950 to modern engines.. they are still in good contition and good compression.
The castoroil is highly polar and has a great affinity for metal surfaces. Castor oil are better to care the engine than syntetics oil, read here:
