I have one of those old engine assembly books that show the piston being dunked in oil just before they slide it into the bore. I had an instructor at a trade school i attended some 40yrs ago(Lincoln Technical Institute) that instructed us on not putting anything on the rings. He said the rings would seat immediately on start up and get oil soon enough. I never used either method in any of the engines i have assembled, but i just spray the rings with an aerosol lubricant (WD40) or whatever i have on hand and wipe the cylinder with the same lubricant and let it rip. Being this build will sit a few years before it runs, thinking it needs some kind of motor oil like others have said. Thanks guys.
