@Straight up rather than oiling my blades, I prefer to Renaissance wax them after stropping on 0.1μm pasted balsa. I do this because my SR's can spent a few weeks between uses.
I find Renaissance wax to be a much easier method to protect the steel. I don't have to clean it off before stropping/shaving. The very thin coating of wax that is on the bevel/edge, gets taken off with my pre-shave stropping. The wax is also beneficial to the strop leather.
A 65g tin of Renaissance wax should last you about 4k to 6k shaves.
