I'm just curious if anyone is running this oil in a gas engine to protect the catalytic converter. If so, any UOA's? Just curious how it is working out.
My first cats failed at 76k, and I think burning oil had something to do with it. I've got a Chrysler 3.8 in my Jeep that uses 1/2 to 3/4 quart of oil every 1k miles, and I think it has something to do with it. These engines are notorious for consuming oil like that, but I've not heard much about people having cats fail with it. I can't help, however, but think it does indeed have everything to do with the short life on mine.
Anyway, I'm pondering what oil would provide the best combination of protection, low ash, and low consumption. Keep in mind, that anything I've run that's heavier than 5w20 has shown less consumption, so I at least want to run a 5w30. I'm currently running M1 0w40 Euro formula, and the engine feels nice and smooth with it (likely my imagination, though). I'm just concerned that it has higher ash content and may be detrimental to the life of the cats.
The engine runs beautifully, with no unusual noise, even when started cold at subzero temps. I couldn't be happier except for the *#&$ oil consumption.
