I'm not real sure it possible to lube the internals of an o ring chain, the same rubber seal that keeps the miniscule amount of grease the chain comes with, will inhibit any new lubricant from entering the internal barrel and pin component of the chain. All one can accomplish is to slick up the contact areas of the sprockets and chain. Any substance that attracts and accumulates grit, speeds up wear in that respect. I use a baked on teflon/moly coating for guns from Brownells on the sprockets and leave the chain dry. Do my methods have any real lubrication benefits, I really have no clue. So when my chain stretches excessively, compared along side a new example I have hanging on a finish nail, I change the sprockets and chain out. The worst thing you can do is to use a spray solvent like WD-40 and wash the petroleum component out of the factory grease and that I'm relatively sure of from experience and just don't practice.
