Picked up a couple of old Daisy BB guns from my wife’s late uncle. I remember wanting one in my youth, but I had to settle for shooting ones at summer camp or friends who had them. I’ve got a model 25 and a Red Ryder, don’t know a lot about them yet. Anyway, the pumps seem to be stuck. Found a Daisy manual for the model 25, and all it says is 20 weight motor oil, but not household oil. What’s recommended?
