Also save 25% by becoming a member or preferred customer. In 2005 the American Petroleum Institute (API) spec changed from SL in 2005  to SM, SN Dexos. 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!

Remembering AMSOIL’S Founder

Mr. Amatuzio was a Man that was absolutely amazing, had great character and integrity . Read Here!


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. AMSOIL’s new CK oils will meet Fords new requirements , WSS-M2C171E along with all major engine manufacturers.

Vehicles with Diesel Particulate Filters

In 2007 on road highway diesel vehicles where mandated to use DPF’s (diesel particulate filters)  by the EPA in the United States and off road vehicles in 2012 over a certain HP, (above 25 HP). During normal operation the DPF’s do a great job in cleaning the exhaust contaminants (NOX) from diesel engines but they definitely do create problems. Some major problems are fuel dilution in the oil (especially in the Ford 6.7L). Some are excessive fuel consumption, back pressure in the exhaust system which limits your performance which can your engine to shut down or go into limp mode and excessive engine wear in certain applications. Contact us to understand these issues and the difference in how they operate or read this article on DPF’s. Click here for a YouTube on diesel particulate fundamentals, far left video. Congress passed a law that made it is legal to remove DPF’s from all emergency vehicles. The main reason is so they will not shut off or go to limp mode during operations!!
