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.

Upravo je to ono kaj sam napisao vezano za cink. Danas se normalnim "cestovnim" automobilom smatraju automobili sa DPFom jer zbog euro norma on je neizbježan. Znači low saps ulja u kojima su cink, fosor i drugi aditivi zamjenjeni drugim ekvivalentima.
U autima bez DPFa kao što rekoh cink je poželjan jer je najbolji aditivi protiv trošenja. Sve se danas prilagođava euro normama pa tako i ulja čak i na "štetu" motora.
