I'm no expert, but at 120ppm, a cat will have longer life than at 500ppm. at 15, I would think there would be no cat problems, but add that biod for lubricity!!!!!
I'm not aware of what causes the breakdown of the cats, other than normal life in a harsh environment. Sulfur would make the cat non-effective.
