I have 3 Daiwa Fuego LT spinning reels - 2 are 2500 series, one is the 1000 series. I've been very satisfied with them although after 2 years of moderately heavy use the 1000 reel is feeling a little less smooth like it needs oil. I'm curious if the spool shaft should receive grease or oil where it enters the reel body, or perhaps even nothing at all?
