Let me try this again, lol. As noted above, an oillite bronze pilot bushing, which is what the better bushings are made from, is an oil infused bushing. It leaches oil. If you grease the id, you seal the pores and the oil cannot leech out and lubricate the tip of your input shaft. So use oil, even if you don't know if your bushing is an oilite type bushing or not. On the od, it does not matter, just the id so use grease if you want on the od.
