I have a low power Daisy Grizzly 840 which I maintain properly but accuracy seems to be falling of. Do pumpers lose FPS over time even if properly cared for? There are no operational signs that it malfunctioning.

Yes. Dust and other stuff can get suspended in the oil, and slowly deteriorate the pump cup or o rings, Or polishing or erodes the metal.

Or pumping alot, causes friction and heat. Nothing much you can do, and it's not your fault.
