Nije stvar samo cinka kao takvog već pepela u ulju koji sadrži aditive (ZDDP-cink, fosfor i dr.) iz kojeg izgaranjem nastaje čađa koja onda začepljuje DPF. Zato u aute sa DPFom idu low saps ulja.
To što ima puno cinka može biti samo plus a nikako minus jer sva ulja prije pojave low saps ulja su bila puna cinka. Cink je poželjan jer smanjuje trenje tj. trošenje sklopova.

Ovaj tekst je sa oficijalne Mobil1 stranice, ne preporucuju preveliku kolicinu cinka/fosfora za cestovne automobile:
Automotive street use oils that meet the latest industry standards are required to have a lower level of zinc and phosphorus anti‐wear chemistries than oils formulated years ago. The latest automotive street use engine oils are designed to be compatible with emission control equipment. Mobil 1 Racing oils are formulated with anti‐wear (zinc/phosphorus) chemistries at twice the level of automotive street oils to provide enhanced protection of highly loaded valve train systems found in some race engines. Based on the high level of anti‐wear chemistries, Mobil 1 Racing oils are not recommended for street use.
