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!

There has been 2 new diesel engine oil spec’s introduced in 2017. The FA-4 is designed for some 2017 and newer diesel engines(it is a lower viscosity) and the CK-4 is backward compatible for 2017 and older with 75% more protection. AMSOIL has the CK-4 spec’ed oils available now, with 6X more wear protection than the industry standard. AMSOIL’S  CK-4 spec’ed oils are more far superior than the earlier CJ-4 oils.  AMSOIL will at a later date have the FA spec’ed oils.
