Herein lies the problem. About 10 years ago, it was also discovered that in general oil consumption, Zinc, especially the phosphorus present in ZDDP, is a primary cause of premature catalytic converter failure.

Diesel oils soon followed suit, until today, no oil that is approved for on-road use contains Zinc. This of course doesn’t affect newer engines with roller lifters or overhead cams at all – but for older engines – it limits the options for oils with ZDDP.
