Never bothered, myself. To quote SRAM
Regular lubrication will extend the chain's service life. Apply oil to the chain links rollers and allow to work in. Clean dirty chains before oiling. Do not use any grease-dissolving or acidic agents. Cleaning agent must be rinsed off after a few minutes with water. Apply oil after chain is completely dried.
I just wait 'till the first time I ride in the rain (not long, usually) after which the chain will need cleaning and oiling with a decent lubricant.
