AMSOIL Synthetic Diesel & Marine Motor Oil SAE 15W-40

Synthetic Heavy-Duty Diesel & Marine Motor Oil SAE 15W-40 (AME) is engineered for all types of diesel engines with an emphasis on modern-day, low emission heavy-duty diesel engines. High 12 TBN controls acids from combustion blow-by and exhaust gas recirculation (EGR). Higher levels of detergency and dispersancy additives reduce soot thickening, oxidation and wear. Defends against bore polishing, deposits and ring-sticking. Extended drain capabilities reduce downtime and motor oil expenses. Delivers clean engine performance.



AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil (AME) is a premium diesel oil providing excellent performance in all types of diesel engines where highly effective control of wear and deposits is vital. Built with heavy-duty dispersant/detergent additives, its 12 TBN chemistry neutralizes acids and controls soot thickening from EGR and blow-by to protect against corrosion, cylinder bore polishing (wear) and varnish/sludge deposits. 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 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
-44°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.

Applications

AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil is engineered for use in a wide variety of light and heavy duty applications, including over-the-road trucks, off road construction, marine engines, farm equipment, mining, industrial (pumps & generators) and personal automotive or commercial transportation. It is excellent for use with low or high sulfur diesel fuels in standard, turbocharged or supercharged engines, including modern low emission diesels such as those equipped with EGR systems.

AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil is recommended for use in diesel engines and other applications requiring any of the listed worldwide specifications and gasoline engines requiring API SL, SJ, SH... or ACEA A3.

Mixing AMSOIL

AMSOIL AME 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 Synthetic Oils.

SERVICE LIFE

AMSOIL Synthetic Heavy Duty Diesel Oil is recommended for extended drain intervals in unmodified¹, mechanically sound² vehicles or equipment as follows:

Diesel Engine Service
• Normal Service³ - Up to 25,000 miles or one year, whichever comes first, or longer based on oil analysis.
• Severe Service⁴ - Up to 15,000 miles or one year, whichever comes first, or longer based on oil analysis.

Gasoline Engine Service
• In gasoline engines, oil drain intervals may be extended up to two times (2X) the OEM recommended drain interval (not to exceed 15,000 miles without oil analysis) or one year, whichever comes first.

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 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.

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 manufacturers.
² Mechanically sound engines are in good working condition and do not, for example, leak oil or consume excessive amounts, are not worn out, do not overheat, do not leak anti-freeze and have properly working emission control systems. AMSOIL recommends repairing malfunctioning engines prior to the installation of AMSOIL synthetic oils.
³ Personal vehicles frequently traveling greater than 10 miles (16 km) at a time and not operating under severe service.
⁴ Turbo or supercharged vehicles, commercial or fleet vehicles, excessive engine idling, first and subsequent use of AMSOIL in vehicles with over 100,000 miles, daily short trip driving less than 10 miles (16km), frequent towing, plowing, hauling or dusty condition driving.
