Simply spraying some lubricant (like Teflon spray for example) onto the chain, running through all the gear combinations, and wiping the excess lubricant off the chain every couple months goes a long way. It helps your bike make less noise, extends the life of your chain, and helps keep your chain from turning totally black with grease. (Which means you're less likely to get grease stains on your pants when you ride.)
