Meets Emission System Requirements
AMSOIL OE 15W-40 Synthetic Diesel Oil is a low-sulfated ash formulation that meets the requirements for low-emission quality diesel oil and protects under the most severe conditions found in modern diesel engines. It is compatible with all exhaust treatment devices and is designed for engines equipped with diesel particulate filters (DPF).

Extreme-Temperature Performance
AMSOIL OE 15W-40 Synthetic Diesel Oil is formulated for improved heat and oxidation resistance over conventional petroleum oil for cleaner engine operation, maintaining power and fuel efficiency for superior engine performance. Its dependable cold-temperature flow assures easier start-up and improved post start-up protection.

Resists Oil Consumption and Emissions
Due to its low rate of volatility (burn-off), AMSOIL OE 15W-40 Synthetic Diesel Oil is able to reduce oil consumption and emissions during operation. It maintains its excellent film strength even during high-temperature operating conditions to ensure dependable protection, performance and fuel efficiency.

Controls Soot-Thickening and Wear
AMSOIL OE 15W-40 Synthetic Diesel Oil is formulated with premium synthetic base stocks and robust detergent/dispersant additives that keep soot particles from agglomerating and forming larger wear-causing particles. The AMSOIL OE 15W-40 Synthetic Diesel Oil formulation allows for optimal soot-related viscosity control to maintain stay-in-grade performance.
