Unsurpassed Engine Protection Against Engine Wear In the Four-Ball Wear Test (ASTM D-4172B) AMSOIL HDD demonstrated better anti-wear performance than competitive petroleum and synthetic oils. Even under high temperatures and pressures, its superior film strength and anti-wear additives help prevent metal-to-metal contact. AMSOIL HDD reduces ring wear, cylinder bore polishing, oil consumption and valve train wear for improved engine life and lower maintenance costs.

Service Life: AMSOIL Synthetic 5W-30 Heavy Duty Diesel Oil is recommended for extended drain intervals in unmodified(1), mechanically sound(2) vehicles or equipment as follows:

Personal Light Truck Diesel or Gasoline Engine Service

• Normal Service(3) - Up to 25,000 miles or one year, whichever comes first, or longer based on oil analysis.



• Severe Service(4) – Up to 15,000 miles or one year, whichever comes first, or longer based on oil analysis.



• 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.

Commercial or Fleet Vehicles, Long-Haul Trucks, Marine Craft, RV, Off-Road Equipment

• Non-EGR equipped diesels – extend drain intervals up to two times (2X) the OEM* recommended drain interval or one year, whichever comes first, or longer based on oil analysis.



• Pre-2007 EGR equipped or low emission diesels – extend drain intervals based on oil analysis or use the OEM* recommended interval.



• Replace Donaldson Endurance™ or AMSOIL Ea™ full flow oil filters at the time of oil change up to two times (2X) longer than the OEM* standard interval, not to exceed 60,000 miles in long-haul trucks.

AMSOIL HDD 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.
