AMSOIL Synthetic 5W-40 Diesel Oil 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: up to three times (3X) OEM recommendation, not to exceed 50,000 miles/600 hours or one year, whichever comes first, for diesel engines; up to two times (2X) OEM recommendation, not to exceed 15,000 miles or one year, whichever comes first, for gasoline engines. Drain intervals may be extended further with oil analysis.

Meets Emission System Requirements
AMSOIL Premium 5W-40 Synthetic 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 filters (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 longdrain additive system (10.4 TBN) deliver superior engine protection, cleanliness and performance over extended drain intervals. AMSOIL 5W-40 Synthetic Diesel Oil provides maximum protection for up to 3X the original equipment manufacturer (OEM)-recommended drain interval and 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 increased fuel economy over conventional 15W-40 diesel oils. When driving at a mix of 55 percent city/45 percent highway, the average improvement is 1.6 percent and at straight highway driving the average improvement is 1.25 percent.
Minimizes Oil Consumption and Emissions
Due to its low rate of volatility, AMSOIL 5W-40 Synthetic Diesel Oil is able to reduce oil consumption and emissions during operation. 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 5W-40 Synthetic Diesel Oil is recommended for diesel engines and, where appropriate, gasoline engines requiring any of the following specifications:
AMSOIL Premium 5W-40 Synthetic 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 5W-40 Synthetic Diesel Oil is recommended for extended drain intervals in unmodified, mechanically-sound vehicles or equipment as follows:
Diesel Engine Service
Gasoline Engine Service
*Operating conditions and drain intervals for normal and severe service are defined by the OEM. Refer to your owner’s manual.
Note: Extended drain intervals are not recommended when using biofuels containing >10% ethanol or 5% biodiesel (B5). Follow OEM drain intervals or extend drain intervals with oil analysis.
