[QUOTE="elrodalexander73, post: 1487784, member: 16217"] The zinc and phosphorus reduction is to extend Nox and soot sensor life. Detroit Diesel and Cummins have asked oil manufacturers to basically do what they did in the early 90s with automotive to reduce oxygen sensor failures. The idle vapor when idling has been ruining nox sensor after nox sensor.. Nox sensors for DD15 one box/Cummins scr Catalyst usually run about $250 each and they also have SCR brick coating issues which can stop the reaction process inside the SCR catalyst.. Trust me it all sucks really bad and it's gonna get worse if we don't start writing our congressmen.. [/QUOTE]
