Raven turntable owners:oiling & what type?

It seems the instructions for oiling the axle/bearing/bearing well indicate a very small amount of oil. I've found extra oil is needed to allow the platter to be more smoothly laid into place and lifted off for cleaning and re-oiling. Too little, and things dry out. What has been your experience with this, and do any of you use a brand or type of oil different from that supplied by TW Acustic? If so, how does it compare regarding effectiveness?
