Either or. I have been running the small Ofna filters because of their size and availability. I just wish that they lasted longer. I don't run at tracks that require INS boxes so the question was more aimed to see what other guys are running at their local tracks/parking lots.
I've tried a few different oils. I actually quite like the Traxxas oil, it's super tacky.
