Factory chain oil? I've never know a chain to be lubed from the factory.
If you are reffering to the white stuff on your new ride's chain, that is a protective coating that is meant to inhibit rust. It is placed there by the chain mfg., not the bike factory. It may look similar to white lithium (BR SuperClean) but it sure ain't.
When you guys say "It's great stuff" what exactly do you mean? On what are you basing this opinion? You obviously can't reapply the stuff since you don't even know what it is, and one application of any lube will not be a good test....just curious what y'all are talking about when you say it's great???
