Here in the states the ZDDP level in diesel motor oil was acceptable until the diesel motors were equipped with catalytic converters, once the diesels were equipped with cats they removed the ZDDP from diesel motor oil too. That happened less than a decade ago, I don't remember the exact year, it seems like about 2006 or something like that. My memory isn't what it used to be.

If the ZDDP level is acceptable, diesel motor oil is fine for use in gasoline engines, it just has more detergents. I used it in the 351C of my 1972 Mustang, and then my 1974 Pantera for several years with no problems.
