I lubricate the felt rings on the Flex 3401's in our garage anytime I'm swapping out backing plates.

If you use this tool as a full time detailer and punish it then probably once a month it would be a good idea to add 2-3 drops or spread a thin film over the face of the ring.

If you over do it you'll find oil being spit out as you buff, do keep in mind, sometimes...
