AMSOIL 5W-40 Premium Diesel Oil

Product Description

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. DEO is also backwards compatible, offering maximum protection to all diesel applications.

Exceeds System Requirements

AMSOIL Synthetic 5W-40 Diesel Oil is a low sulfated ash formulation that exceeds the modern requirements for low emission quality diesel oil. It is compatible with all exhaust treatment devices and is designed to extend the service life of particulate filters.

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, and 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.

Fleet Savings vs. conventional 15W-40	1 Truck	50 Trucks
Fuel Economy Savings (1.6%)	$960	$48,000
Extended Drain Savings	$201	$10,050
Total Savings with AMSOIL	$1,161	$58,050

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.

Product Applications

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

Compatibility

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.

Service Life

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:

Diesel Engine Service

Three times (3X) OEM* recommendation, not to exceed 50,000 miles/600 hours or one year, whichever comes first. Drain intervals may be extended further with oil analysis.
2007-2009 Caterpillar C13, C15 on-highway engines must follow OEM drain interval.
2007-2010 Dodge 6.7L, Ford 6.4L, GM 6.6L LMM light duty diesel pickups must follow OEM drain interval. Drain intervals can be extended further with oil analysis.

Gasoline Engine Service

Two times (2X) OEM* recommendation, not to exceed 15,000 miles or one year, whichever comes first.

*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.

For best performance, use AMSOIL Ea™ and Donaldson Endurance™ full flow oil filters are designed for extended drain intervals. They stop smaller particles, have less restriction and last longer than regular filters.

AMSOIL Ea By-pass oil filters are specialized for the removal of small, wear-causing dirt particles, thereby extending engine life. AMSOIL encourages using an AMSOIL Ea By-pass filter system for maximum engine and oil life.

AMSOIL offers a cost-effective, quality oil analysis services. When running extended drain intervals an oil analysis should be performed. more information
