We used to have recycled oil here, I'm sure it was pretty good stuff, Mercedes approved it's use for buses in Auckland city. I was using it in a mid '50's BSA single (B31/33) Trying to make it home with a flogged out gudgeon pin, I was using the manual retard to retard the ignition to stop the vibration. Stopped on a ridge to let it cool down, the oil was dripping out of the rockers like kerosene. I'm sure any oil would be doing the same, but I didn't like that and never used it again. The bike didn't start at the bottom of the hill, it got so hot the rings collapsed, and had to hitch home. Came back with another top end to get it home.
I don't think any oil I've used has caused engine problems....maybe.
