AMSOIL AME resists heat and breakdown better than conventional petroleum oils for long lasting performance and protection.

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.

Extends Drain Intervals
AMSOIL AME can extend drain intervals far beyond those recommended for conventional petroleum oils. Its unique synthetic formulation and long drain additive system deliver the best possible engine protection, cleanliness and performance over extended drain intervals, reducing vehicle maintenance and waste oil disposal costs.

Advanced Soot and Wear Control Formula
AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil is heavily fortified with detergent/dispersant additives and is naturally resistant to soot. It keeps soot particles suspended independently, preventing them from attaching together to form larger, wear-causing particles. Viscosity increase is minimized and soot related wear is controlled.

Maximizes Fuel Economy, Reduces Oil Consumption and Emissions
AMSOIL AME has lower high temperature volatility (evaporation) than conventional petroleum oils. Because less oil vapor passes into the combustion chamber, oil consumption and emissions are reduced. Lower volatility helps AMSOIL AME retain its viscosity after high temperature service for excellent fuel economy and continued dependable protection.

Excellent Cold Flow Properties
AMSOIL AME remains fluid down to -51°F. It eases cold weather starting and provides vital start-up lubrication to prevent engine wear. AME outperforms conventional 15W-40 petroleum oils and greatly minimizes the impact of cold weather operation.

Replace AMSOIL Ea™ full flow filter at the time of oil change up to 25,000 miles. Replace other brand oil filters at standard OEM* intervals.

*OEM = Original Equipment Manufacturer

⁽¹⁾ Engines operating under modified conditions are excluded from extended drain recommendations. Examples include the use of performance computer chips; non-OEM approved exhaust, fuel or air induction systems; and the use of fuels other than those recommended for normal operation by the manufacturer.

⁽²⁾ Engines are in good working condition and within the factory design settings. Mechanically sound engines, for example, do not leak oil or consume excessive amounts, are not worn out, do not overheat, do not have internal or external anti-freeze leaks and have a properly working emission control system. AMSOIL recommends repairs be made to malfunctioning engines prior to the installation of AMSOIL synthetic oils.

⁽³⁾ Personal transportation vehicles frequently traveling greater than 10 miles (16 km) at a time and not operating under severe service.

⁽⁴⁾ Extensive engine idling, daily short trip driving less than 10 miles (16 km), frequent towing, plowing, hauling heavy loads or dusty-condition driving.

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. For best performance, use AMSOIL Ea or Donaldson Endurance oil filters.

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

Unsurpassed Diesel Engine Protection

Diesel engine emissions have been an ongoing environmental concern for the past few decades, and the United States, Europe and Japan have responded to demands to reduce harmful particulates and nitrogen oxides (NOx). In the U.S., particulate and NOx levels were first regulated in 1988, with regulations becoming increasingly stringent through the years. In fact, 1988 standards set NOx and particulate levels at 14.4 g/kWhr (grams/kilowatts – hour) and 0.8 g/kW-hr respectively, while 2010 standards have been set at 0.27 g/kW-hr and 0.013 g/kW-hr respectively. By 2010, diesel engines will be considered “clean,” but getting there will require sulfur-free fuel, improved in-cylinder combustion, exhaust after-treatment, vehicle design changes and diesel oils that are compatible with after-treatment systems.

Between the years 1988 and 1991, emission standards were met by improving in-cylinder combustion through the use of unit injectors, electronic controls, controlled air swirl, improved combustion bowl design, reduced piston crevice volume, turbo-charging, air inter-cooling and reductions in oil consumption.

The year 1991 also saw the use of high top rings to lower particulate emissions. By 1998, retarded fuel injection timing was introduced to meet increasingly stringent NOx emission standards. High top rings and retarded fuel injection timing increased soot loading on the oil, leading to the introduction of API diesel oil category CH-4 in order to prevent viscosity increases and increased wear due to soot.

In order to meet 2002 emission standards, most engine manufacturers introduced exhaust gas recirculation (EGR) engines, which recirculate a portion of the exhaust to the engine’s combustion chamber, lowering peak combustion temperature. Although EGR engines effectively reduce emissions, they also run hotter and introduce higher levels of soot and acid into the oil, leading to increased wear, increased oil viscosity and shorter oil drain intervals.

The API CI-4 diesel oil specification was introduced in December 2001 to protect against the higher temperatures and increased levels of acids, soot and oxidation associated with EGR engines, while some manufacturers released their own diesel oil performance specifications in order to assure optimum protection for their equipment. Mack released its stringent EO-N Premium Plus High Performance Diesel Engine Oil specification in the spring of 2002, then upgraded it to EO-N Premium Plus 03 in April 2003 due to soot-related oil thickening and shear that occurred after a certain length of highway time.

API issued an upgrade to its CI-4 specification, CI-4 PLUS, in September 2004 in order to provide improved oxidation resistance, shear stability, acid neutralization and soot dispersancy for EGR engines. CI-4 PLUS certified diesel oils also meet most of the individual manufacturer issued specifications and are backward compatible with older diesel oil specifications and engines. CI-4 PLUS oils must first meet the original requirements of CI-4, with the additional requirements of passing the 90-Pass Shear Stability Bench Test and the Mack T-11 engine test, a more stringent upgrade of the Mack T-8E soot-viscosity test required for CI-4.

In order to meet 2007 particulate standards, exhaust after-treatment devices such as particulate filters (DPF’s) and continuously regenerative traps (CRT’s) will be incorporated into diesel engines, creating new challenges for diesel oils. AMSOIL Synthetic Diesel Oils are ahead of the curve and ready to meet the challenges of tomorrow.

AMSOIL Synthetic Diesel Oils surpass the most stringent modern diesel oil specifications, including CI-4 PLUS and EO-N Premium Plus 03. Formulated with top-of-the-line synthetic base stocks and advanced additive packages, AMSOIL Synthetic Diesel Oils effectively control the increased soot and acid levels associated with EGR units, while remaining shear stable at high temperatures, avoiding the damaging sludge and deposit build-up that contribute to decreased fuel efficiency, corrosion and accelerated engine wear. The drain intervals of AMSOIL diesel oils may be extended by oil analysis in EGR-equipped engines.

Emission control technology has increased soot loading of diesel oils, prompting original equipment manufacturers to shorten drain interval recommendations. Even at increased soot levels, AMSOIL Synthetic Diesel Oils continue to offer outstanding wear protection. Soot and iron wear levels were measured over 900 hours of operation in a 2002 EGR-equipped Mack LE613-Rear Loader running AMSOIL 15W-40 Synthetic Heavy Duty Diesel and Marine Motor Oil. As seen in the graph, even at increased soot levels, the rate of engine wear remained well below the Mack condemnation limit of 0.5 parts per million per hour (ppm/h).
