As you might be able to guess since there seems to be two solid sides to this issue, it likely really doesn't matter which you choose to do. But do choose to care for it on a regular basis by keeping it clean and lubed. There are many choices on both the cleaning and lubing. Pick one and do it regularly and you won't be dealing with the rusty, dirty chain we likely all have seen on friends and neighbors neglected chains. Which ever you choose, if done regularly, will give you good chain and cog life.
