If shipping were not more expensive than the oil, I'd have you send a bottle for lubing the blades on my hair clippers, Singer oil sounds perfect. I needed to lube them once when away from home base, used olive oil, that dried to a stickiness and gummed them up. Cleaned and lubed with a couple drops of ATF just because of its thin viscosity, worked great.

Going back to wax will be best for me. With oil, pulling the chain off was a mess, but with wax, it won't be, so needing to do that for the hot melt will not be a chore. But if I stayed with oil, an on-bike chain cleaner is immensely helpful to make it a 5 minute job with no mess, so able to do much more frequently, I do it when the lube is visibly pasty from metal particle buildup, about 600-700 miles. With wax, those metal particles would mostly be on the ground.
