15W-40 Max-Duty Synthetic Diesel Oil

15w40 diesel oil max-duty synthetic Amsoil

AMSOIL 15W-40 Signature Series Max-Duty Synthetic Diesel Oil
Product Code: DME

Technical Data Sheet (pdf)

API CK-4 / SN, CJ-4, CI-4+, CF and more.

This oil meets the Ford WSS-M2C171-F1 spec

Recommended for all year diesel engines (backward compatible) specifying a 15W-40. DME is the primary 15W-40 recommendation for model-year 2007 and later diesel engines with DPF / SCR / DEF (Diesel Particulate Filter / Selective Catalytic Reduction / Diesel Exhaust Fluid). Maximum protection for extended drain-intervals.

Max-Duty synthetic diesel oil uses top-tier synthetic base oil and is naturally resistant to oxidation and the thickening effects of soot contamination. Boosted detergent/disperant additives keeps soot particles suspended which helps prevent the formation of larger soot particles that cause wear. DME Max-Duty synthetic diesel oil has a lower volatility (less burn-off) which helps retain viscosity after high-temperature use thus maximizing engine protection.

Outstanding Protection for Ford* Powerstroke* Engines


Ford Motor Company recently released its position on the upcoming new API CK-4 and FA-4 diesel oil specifications, claiming it will only recommend diesel oils that meet the Ford WSS-M2C171-F1 specification or oils formulated specifically for the previous API CJ-4 specification.

Questions have arisen regarding why Ford would condemn use of CK-4 and FA-4 products in its Powerstroke engines. According to Ford Service Lubricant Technical Expert Ron Romano, “6.7L engines tested on CK-4 and FA-4 formulations had experienced valve train wear not encountered with CJ-4 formulations. The CJ-4 formulations in question contained more than 1,000 parts per million phosphorus, an effective antiwear ingredient, while the CK-4 and FA-4 formulations were below that threshold. As a result, Ford declared that it has wear concerns about the use of CK-4 and FA-4 formulations with less than 1,000 ppm phosphorus in new and older Ford engines.”

All current AMSOIL synthetic diesel oils contain a boosted level of wear protection above the requirements set by the Ford specification. The new Signature Series Max-Duty Synthetic Diesel Oil and Heavy-Duty Synthetic Diesel Oil formulations [launched 6 February 2017] also contain boosted levels of wear protection, and they carry the Ford WSS-M2C171-F1 specification.
Customers can be well-assured that all Ford Powerstroke engines, no matter the model year, are well-protected when using AMSOIL synthetic diesel oils.
