Seems like I have read somewhere on this forum that one should not use grease on fly reels, but should use oil only. I think it was Mikechell, but I am not certain. I would hope that this were true as I don't like using grease for it being messy and sometimes hard to apply. I would prefer to use only oil for it's ease of application if nothing else. If one should not use grease, then why do most reel manufacturers say to apply grease on certain parts of the reel? I could see using a small amount of grease on the gear teeth only, but oil everywhere else. I collect vintage fly reels and most of them I get are caked with old dried out grease on the spool shaft, the drag or click gear and on anything that moves or turns. Once this old grease is cleaned off and replaced with a good oil, they work great.
