I really would not use oil in a ball bearing; it will lead to very premature failure unless you are going to do a lube after every ride.
If you want to try light weight grease, the best possibilty would be would probably be Lubriplate available at almost any hardware store.
Of course, I also think this whole thing is an exercise in futility.
