I have not greased it, its only been used on one trip and the drag was extremely smooth out of the box, if it becomes rough i will grease it.
These are much better than the standard spool, more drag and a steeper curve and cast huge
I will say that the line capacity was overstated i feel, it said it could hold 260m of pe 8 but i would not push it past 220, also took bang on 300m spool of pe 6
