ON your bearings is entirely pointless. But it can do some good IN your bearings. The kind of bearings used in skateboards do need some sort of lubrication. It can be either oil or grease. Oil does make the bearing spin a little easier, but doesn't stay in the bearing very well. If you run oil you need to relube fairly often, or run the risk of trashing the bearings. Grease will spin a little slower, but it'll stay in place better. You can go longer between cleans and lubes. Your choice. Me, I use grease, but a fairly small amount. Means I don't lose that much spin, and the bearings will survive rolling through an occasional puddle. Speaking from personal experience where my step dad was trying to be nice and grease my bearring for me so I would have a smoother ride. No. If it is just a normal wheel grease it is not good. It will give you a smoother and quitter ride, but be expecting to go much slower and getting much more leg exercise from pushing.
