These new oil specifications limit the amount of zinc and phosphorous (ZDDP) by approximately 30% less, this is detrimental to flat tappet camshafts & lifters! Now a new PCMO (passenger car motor oil) spec is coming in future (2019) and AMSOIL currently has it in all 3 tiers. It is designed for newer GDI engines that experience Low speed engine pre-ignition (LSPI), it will meet Dexos 1 gen 2 spec’ed oil, it will also meet the SP spec when API releases it. These new oils by AMSOIL are the pinnacle in performance with 75% more protection and 100 % protection against LSPI (low speed pre-ignition). Gas Direct Ignition (GDI) engines will be in most new vehicles by 2020!
