Heavy-Duty Engine Protection

Wear on rings and cylinder liners leads to increased oil consumption and loss of compression, resulting in reduced horsepower and fuel economy. Independent testing shows Amsoil Heavy-Duty Synthetic Diesel Oil 5W-40 (ADO) delivers 4X more wear protection than required by the Detroit Diesel DD13 Scuffing Test for Specification DFS 93K222 to help maximize equipment life and reduce maintenance costs and downtime.

Viscosity Control

Formulated with advanced synthetic base oils and detergent/dispersant additives, Amsoil Heavy-Duty Synthetic Diesel Oil 5W-40 (ADO) minimizes viscosity change while keeping soot particles suspended independently, helping prevent the formation of larger, wear-causing particles. Lower volatility also helps Heavy-Duty Synthetic Diesel Oil retain its viscosity after high-temperature service for added engine protection and increased fuel economy.

Excels in Temperature Extremes

Amsoil Heavy-Duty Synthetic Diesel Oil 5W-40 (ADO) is formulated to deliver improved heat and oxidation resistance compared to conventional diesel oils. It provides clean engine operation and helps maintain power and fuel efficiency for superior engine performance. Amsoil Heavy-Duty Synthetic Diesel Oil 5W-40 (ADO) also flows dependably in cold temperatures for easier startup and improved engine protection.

Oil Consumption Minimized

Amsoil Heavy-Duty Synthetic Diesel Oil 5W-40 (ADO) has a low rate of volatility (burn-off), reducing oil consumption during operation and passing less oil vapor into the combustion chamber. It provides up to 66 percent less oil consumption than required by the API CK-4 standard in the Caterpillar-1N oil consumption test.

COMPATIBILITY

Amsoil Signature Series 5W-40 Heavy Duty Synthetic Diesel Oil (ADO) is compatible with other conventional and synthetic engine oils. Mixing Amsoil diesel oils with other oils, however, will shorten the oil’s 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 diesel oils.

SERVICE LIFE

  • Diesel Engine Service Life: Heavy-Duty On-/Off-Road: Three times (3X) OEM1 recommendation, not to exceed 60,000 miles/600 hours or one year, whichever comes first.
  • Turbodiesel Pickup: Two times (2X) OEM1 recommendation, not to exceed 25,000 miles or one year, whichever comes first.

  • Diesel Engine Service Life: Two times (2X) OEM1 recommendation, not to exceed 15,000 miles or one year, whichever comes first.

  • Drain intervals may be extended further with oil analysis.

1Refer to your owner’s manual for OEM drain interval recommendations and guidelines for severe and normal service.

Note: Extended drain intervals are not recommended for performance-modified engines, when using biofuels containing more than 10 percent ethanol or 15 percent biodiesel (B15) or for 2007-2009 Caterpillar* C13 and C15 on-highway engines. Extend drain intervals beyond OEM recommendations in these instances only with oil analysis. Note: 2007-2010 Dodge**, Ford** and GM** turbodiesel pickups are also not recommended for extended drain intervals when using ADO.
