Key Benefits
- Advanced synthetic-blend oil with greater than 50% synthetic content
- 2X better wear protection in third-party Detroit Diesel DD13 Scuffing testing (DFS 93K222, 10W-30 worst-case)
- Minimizes viscosity change and keeps soot particles suspended independently
- Improved heat and oxidation resistance compared to conventional diesel oils
- Dependable cold-temperature flow for reliable startup
- Low volatility — fewer combustion-chamber deposits and longer aftermarket-system life
- Broad OEM coverage — Volvo, Mack, Cummins, Caterpillar, Detroit Diesel and more
- Does not void new vehicle or equipment manufacturer warranties; covered by the AMSOIL Limited Warranty
Wear, Viscosity Control, Temperature and Oil Consumption
Heavy-duty engine protection: Third-party testing shows AMSOIL Commercial-Grade Diesel Oil delivers 2X more wear protection (Detroit Diesel DD13 Scuffing Test for specification DFS 93K222, using 10W-30 as worst-case representation) to help maximize equipment life and reduce maintenance costs and downtime.
Viscosity control: Greater than 50% synthetic content and high-performance detergent/dispersant additives minimize viscosity change while keeping soot particles suspended independently, helping prevent the formation of larger, wear-causing particles.
Excels in extreme temperatures: Improved heat and oxidation resistance compared to conventional diesel oils, plus dependable cold-temperature flow for reliable startup.
Minimizes oil consumption: A low rate of volatility (burn-off) reduces oil consumption and passes less oil vapor into the combustion chamber, contributing to fewer combustion-chamber deposits and longer aftermarket-system life.

It’s a synthetic blend but it’s a higher content blend than the rest. All my company trucks run it and it seems to working out great for all of them. Better fuel mileage and better engine temperatures!
