I'm with Geno on this. A very thin application of synthetic clean and lube product such as Tri-Flow or Breakfree applied after each cleaning and allowed to dry is all the lubrication a hinge pin needs for an honest day of hunting or a 200 target day at the range. If you shoot more than that between cleaning/lubricating I suppose you could be needing to pack your hinge pin like a wheel bearing with a product like the Mobil Oil synthetic lubricants.
