My dealer tells me that the o-ring chain really does not need the oil type lubrication and that it would just make a horrible mess to have to deal with. He reccommends using the chain wax aerosol which acts more as an anti-corrosive than a lubricant. Is this correct advice? Also, all my riding is on paved, dry roads so what shoud be the frequency of lubrication. The owner's manual says to clean the chain prior to applying a lube if it appears to be dirty. What is "dirty"? Greasy? How can you tell if the chain should be cleaned before applying the lube?
