ZDDP was not, and is not "phased out".

It has been generally reduced, not eliminated.

There's the REAL problem. The cam companies blamed the failure of their poor product on the oil, using the EPA as a scapegoat. And because anyone with sense does not trust the Government to act in our best interest, it was an easy "sell"--getting us to believe the EPA-mandated ZDDP reduction in the oil was the problem when it was really cheap, imported, defective cams 'n' lifters.

Yeah, the detergent/ZDDP balance is better now. Live 'n' learn.
