Are there any additives out there that can legitimately clean or lengthen the life of catalytic converters? My Jeep burns oil, and one or both cats had to be replaced at about 76k miles.
I'm now running M1 0w40 to reduce consumption, but it is about 10% higher in phosphorus than regular M1, and even more so than an oil like M1 AFE. I'm just wondering if the higher phosphorus in the 0w40 will shorten the life of the cat, as the engine burns oil, and if so, is there an additive that can "clean" the cat.
I'm not sure if I'd be looking for an oil additive or a fuel additive, if it exists, so I'm posting in both forums.
