AMSOIL Synthetic 5W-40 Diesel Oil (DEO) is the premium choice for API CJ-4 emission-quality diesel oil required by model-year 2007 and newer diesel engines. It delivers extraordinary lubrication in diesel engines found in commercial, fleet and personal vehicles. Built with the latest additive and synthetic base oil technology, AMSOIL Premium Synthetic 5W-40 Diesel Oil exceeds the higher performance demands of modern engines. It withstands the stress of heat, soot and acids to help prevent deposits, wear and corrosion. AMSOIL Synthetic 5W-40 is wax-free with a broad viscosity range to provide exceptional cold-weather starting and high temperature protection. It resists breakdown and offers maximum fuel efficiency over extended drain intervals.
AMSOIL, the leader in automotive synthetic lubrication, produced the world’s first API-qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL, The First in Synthetics,® to do the best job protecting your engine.
Exceeds Emission System Requirements
AMSOIL Synthetic 5W-40 Diesel Oil is a low-sulfated ash formulation that exceeds the requirements for low-emission quality diesel oil. It is compatible with all exhaust treatment devices and is designed to extend the service life of diesel particulate fi lters (DPF).
Extended Drain Performance
AMSOIL Premium 5W-40 Diesel Oil can extend drain intervals far beyond those recommended for conventional petroleum oils. Its unique synthetic formulation and long-drain additive system (10.4 TBN) deliver superior engine protection, cleanliness and performance over extended drain intervals. AMSOIL Synthetic 5W-40 Diesel Oil provides
maximum protection for up to 3X the OEM-recommended drain interval, even further with oil analysis.
Improves Fuel Economy
The advanced synthetic technology used to engineer AMSOIL Premium 5W-40 Diesel Oil enhances viscosity properties and is proven to deliver better fuel economy. In fact, the Environmental Protection Agency’s (EPA) Federal Test Procedure confirms that AMSOIL 5W-40 Diesel Oil provides up to 3 percent better fuel economy than conventional 15W-40 diesel oils.

Reduces Oil Consumption and Emissions
AMSOIL Synthetic 5W-40 Diesel Oil has lower volatility (burn-off) than conventional petroleum oils. Because less oil vapor passes into the combustion chamber, oil consumption and emissions are reduced. Lower volatility helps AMSOIL Premium Diesel Oil retain its viscosity after high-temperature service for dependable protection and excellent fuel economy.
Controls Soot-Thickening and Wear
The advanced synthetic base oils in AMSOIL 5W-40 Diesel Oil are naturally resistant to soot contamination. That, along with a heavy fortification of detergent/dispersant additives, keeps soot particles suspended independently, helping prevent the formation of larger wear-causing particles. Viscosity increase is minimized and soot-related wear is controlled.
AMSOIL Premium CJ-4 Synthetic 5W-40 Diesel Oil is recommended for diesel engines and, where appropriate, gasoline engines requiring any of the following specifications:
• SAE 5W-40 • API CJ-4, CI-4+, CF, SM
• ACEA E7, E9 • Mack EO-O Premium Plus
• DDC Power Guard 93K218
• Caterpillar ECF-3, ECF-2 • Cummins 20081
• Volvo VDS-4 • MB 228.31 • MTU Type I & II
• MAN 3275 • JASO DH-2 • Global DHD-1
• Renault RLD-3
AMSOIL Synthetic 5W-40 Diesel Oil is compatible with conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed. Aftermarket oil additives are not recommended for
use with AMSOIL motor oils.
AMSOIL Premium API CJ-4 Synthetic 5W-40 Diesel Oil (DEO) is recommended for extended drain intervals in engines that are unmodified and in good operating condition:
