That's why you want to avoid products that are known to damage catalytic converters, such as high-phosphorus, non-API motor oil.

I'm still waiting to see proof of a real world test where this proven. I did read an article where they ran a bench test and caused an oil leak that pumped far more oil into the converter than would normally happen in real world conditions, according to that same report. If you have proof, cool, post it somewhere we can all read it.

Well, might not be "proof" to you, but on my wife's 1988 New Yorker (3 liter Mitsu-shitty) I was changing oil every 3 months, occaisionally stretching to 6 (car got about 12000km a year put on it) and the converter started to rattle and the car failled the E-test. I replaced the cat, and all was fine, for another 2 years. I was not noticing any apreciable oil consumption - never had to add between changes, and NEVER saw or smelled any oil smoke. Car failed again so I started to investigate. Figured the cat had died again - but what caused it? I removed the cat and started the car and it became quite obvious it was burning oil. I decided to check the valve seals, and it became obvious why the engine was smoking, with the typical failed Mitsu-shitty valve guides. Installed rebuilt heads and another new cat and passed with flying colors. Was it the oil, or the Phosphorous in the oil that killed the cat?? We'll likely never know - but I did switch to the ZDDP free oil from the "all fleet" that had been used. -- Posted via a free Usenet account from http://www.teranews.com

I dunno, I have seen some cars on the road that seemed to be burning more oil than gasoline. Real-world conditions can be pretty harsh. --scott -- "C'est un Nagra.
