15w-40: AMSOIL 15w40 Synthetic Diesel & Marine (AME)

Product Description

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 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 -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.
