If you listen to what Peggy Hall says, use Teflon-based thick grease (SuperLube). Don’t put it into the bowl; rather, unscrew the pump and put it there from the back end. It should last a year or so.
Any oil in your holding tank would only create clogs.

The manufacturer sells something, but suspect there is a generic cheaper alternative. I've used vegetable oil in the past, but that seems gum up the pump. A friend uses motor oil but I worry about it not being compatible with the rubber parts. Fred Hazzard S/V Fury C&C 44 Portland, Or
