One of the great controversies of chain maintenance is whether you should oil a chain or not. The downside of oiling a chain is that the oil may carry grit into the interior of the chain, and that this grit-mixed-with-oil will act as grinding compound, causing accelerated wear. Many experts whose judgement I highly respect hold this opinion, but I do not believe that this is always the case. I have no doubt that this "grinding-compound" effect can occur, but the severity of the risk depends upon the sort of dust/soil prevalent in a given area, and, particularly, the oiling technique used.
