(I couldn't find the P & Zn content for 10W-30 Amsoil ACD)



A UOA from two years ago had zinc and phos. At:

phosphorus-----------1180
zinc-------------------1339

I haven’t seen any more recent UOAs or VOAs on this oil. But it’s still an API CI+4 HDEO so I’m not sure if those numbers would be any different today?
