AMSOIL 15W-40 Commercial Grade Diesel Oil

AMSOIL 15W-40 Commercial Grade Diesel Oil is an advanced synthetic-blend, formulated with over 50% synthetic content, making it ideal for commercial equipment and heavy-duty diesel engines. This oil provides twice the wear protection as compared to the minimum standards set by Detroit Diesel's DD13 Scuffing Test, ensuring enhanced equipment life and reduced maintenance costs. It excels in extreme temperatures, with a cold-pour point at -36°C (-33°F), allowing for quick oil flow during cold startups. Additionally, it maintains steady viscosity consistency, resists oil consumption, and contains a robust detergent package for cleaner engine internals. It meets various industry specifications like API CK-4, CJ-4, CI-4+, CF, and several others, demonstrating its versatility and reliability across different diesel engine types. The semi-synthetic formula offers all-climate performance, ensuring reliable operation in a wide range of environmental conditions. Its enhanced formula helps minimize viscosity change, keeps soot particles suspended independently, and prevents the formation of larger, wear-causing particles, thus minimizing oil consumption and ensuring consistent wear control throughout the service interval. It's suitable for extended service intervals when following oil analysis recommendations and can be mixed with other conventional, semi-synthetic, and synthetic diesel engine oils​.

Commercial-Grade Diesel Oil

Formulated for Long Engine Life

AMSOIL Commercial-Grade Diesel Oil is an advanced synthetic-blend oil with greater than 50% synthetic content. Specially engineered for commercial equipment, it provides 2Xbetter wear protection,1 helping you keep trucks and equipment operating at peak performance. AMSOIL Commercial-Grade Diesel Oil provides outstanding value and excellent protection for customers seeking an upgrade over conventional diesel oils.

AMSOIL 15W-40 Commercial-Grade Diesel Oil

Heavy-Duty Engine Protection

Wear on rings and cylinder liners leads to increased oil consumption and loss of compression, resulting in reduced horsepower and fuel economy. Third-party testing shows AMSOIL Commercial-Grade Diesel Oil delivers 2X more wear protection to help maximize equipment life and reduce maintenance costs and downtime (based on third-party testing in the Detroit Diesel DD13 Scuffing Test for specification DFS 93K222).

Viscosity Control

Formulated with greater than 50% synthetic content and high-performance detergent/dispersant additives, AMSOIL Commercial-Grade Diesel Oil minimizes viscosity change while keeping soot particles suspended independently, helping prevent the formation of larger, wear-causing particles.

Excels in Extreme Temperatures

AMSOIL Commercial-Grade Diesel Oil is formulated to deliver improved heat and oxidation resistance compared to conventional diesel oils. It provides clean engine operation and helps maintain power and fuel efficiency for strong engine performance. AMSOIL Commercial-Grade Diesel Oil also flows dependably in cold temperatures for reliable startup and engine protection.

Minimizes Oil Consumption

AMSOIL Commercial-Grade Diesel Oil has a low rate of volatility (burn-off),reducing oil consumption during operation and passing less oil vapor into the combustion chamber. This contributes to fewer combustion-chamber deposits and longer aftermarket-system life.
