New AMSOIL Synthetic Diesel Oils: Get Ready for Change


New Signature Series Max-Duty Synthetic Diesel Oil and Heavy-Duty Synthetic Diesel Oil represent a leap forward for diesel engine protection and performance. Diesel oil is undergoing a major change. The new API CK-4 and FA-4 diesel oil specifications are here, and an overhauled AMSOIL synthetic diesel oil lineup launches Feb. 6, bringing even better protection and performance with it.


New Specifications, New Diesel Oils


The new API CK-4 and FA-4 specifications focus on these six goals:
  • Improved wear protection 
  • Reduced emissions
  • Improved fuel economy
  • Stronger oxidation stability
  • Better shear stability
  • Increased resistance to aeration
The new API CK-4 specification is designed for current model-year and older diesel engines and is backward-compatible with API CJ-4 (and prior) oils.Going forward, all applications calling for a diesel oil meeting API CJ-4 (and prior) specifications should use an API CK-4 diesel oil.

The new API FA-4 specification is designed to further improve fuel economy and reduce emissions. FA-4 oils are not backward-compatible and may only be used in certain 2017 and newer over-the-road trucks, when approved by the original equipment manufacturer (OEM).

Launching in February, new AMSOIL Signature Series Max-Duty Synthetic Diesel Oil and Heavy-Duty Synthetic Diesel Oil will replace AMSOIL Premium Synthetic Diesel Oil (DEO, DME) and OE Synthetic Diesel Oil (OEC, OED).

AMSOIL Signature Series Max-Duty Synthetic Diesel Oil

Signature Series Max-Duty Synthetic Diesel Oil represents the top tier of AMSOIL protection and performance for diesel engines. Signature Series will be available in 5W-30, 0W-40, 5W-40 and 15W-40 viscosities.
  • Exceptional cold-temperature performance
  • 6X more engine protection*
  • Significantly exceed industry requirements
  • Full OEM specification coverage
  • Reduced oil consumption

Extended Drain Intervals

AMSOIL Signature Series Max-Duty Synthetic Diesel Oil is recommended for extended drain intervals. Its robust formulation allows us to reintroduce extended drain intervals for turbodiesel trucks.

Heavy-Duty On-/Off-Road Diesel Engines: 3X OEM recommendation, not to exceed 60,000 miles, 600 hours or one year, whichever comes first.

Turbodiesel Pickups: 2X OEM recommendation, not to exceed 25,000 miles or one year, whichever comes first.

Gasoline Engines: 2X OEM recommendation, not to exceed 15,000 miles or one year, whichever comes first.

Drain intervals may be extended further with oil analysis.

AMSOIL Heavy-Duty Synthetic Diesel OilAMSOIL Heavy-Duty Synthetic Diesel Oil will provide outstanding protection and performance for customers seeking an upgrade over conventional and other synthetic diesel oils. AMSOIL Heavy-Duty Synthetic Diesel Oil will be available in 10W-30, 5W-40 and 15W-40 viscosities.
  • 4X more engine protection*
  • Excellent opportunity for price-conscious customers to move up to AMSOIL quality
  • Reduced oil consumption 
AMSOIL Heavy-Duty Synthetic Diesel Oil is recommended for OEM-recommended drain intervals.

API Licensing
Unlike OE Diesel, new AMSOIL Heavy-Duty Synthetic Diesel Oil will not be API-licensed. Our philosophy has always been to set a target for quality and formulate products that meet that target. The API licensing system is a voluntary certification that only sets minimum quality standards. Because it is a standard, licensing limits the flexibility we need to quickly adopt new technologies that can improve protection. Our research indicates many diesel enthusiasts and people who depend on their diesel to make a living focus more on protection than on the API doughnut. We are in that camp.

That is why we use specifications like CK-4 as the minimum and engineer protection into our products that goes beyond API standards. We want to give customers the most protection we can, and sometimes that requires opting out of a licensing program. Diesel customers can rest assured their equipment is protected, and we back them up with our warranty.

AMSOIL CI-4+ Synthetic Diesel Oils
The AMSOIL CI-4+ synthetic diesel oil lineup will remain available as additional options for pre-2007 diesel applications not equipped with diesel particulate filters (DPF).
