Ceramic IKBS - To Lube or Not to Lube?

[Tasmaniac]

I recently acquired a FG Bodega with the Ceramic IKBS upgrade. It's just incredibly smooth but after dozens of flips I've noticed that it can occasionally feel stiffer... almost like a "dry" feel. I've blown it out with compressed air and that seems to help, but I was wondering if a drop or two of nano-oil or another type of lubrication would do any good.

My gut feel is that it's probably better to leave it dry, but I would appreciate any insight that others may have.

Note: I'm sorry if this question has already been asked and answered but I couldn't find anything that specifically pertained to ceramic IKBS.

Thanks!
