AMSOIL Heavy-Duty Diesel Engine Oil

AMSOIL Heavy-Duty Diesel Engine Oil

AMSOIL Heavy-Duty Diesel Engine Oil provides advanced synthetic protection for hardworking diesel engines. Whether you drive a diesel pickup, manage commercial trucks or operate heavy equipment, AMSOIL synthetic technology helps protect critical engine components under demanding operating conditions.

Diesel engines regularly face heavy loads, high temperatures, soot contamination and extended operating hours. Therefore, choosing a high-quality diesel engine oil can make an important difference in engine protection and long-term reliability.

AMSOIL synthetic diesel oils are engineered to fight wear, resist oxidation, maintain viscosity and control deposits. They also provide excellent protection in temperature extremes. As a result, you can confidently protect the trucks and equipment you depend on for work, towing, hauling and everyday driving.

Synthetic Protection for Hardworking Diesel Engines

Heavy-duty diesel engines place tremendous demands on lubricants. High operating temperatures can accelerate oxidation, while soot contamination can cause oil to thicken. In addition, towing, hauling and extended operation place additional stress on critical engine components.

AMSOIL Heavy-Duty Diesel Engine Oil is formulated to meet these challenges.

Key benefits include:

  • Helps protect critical components against engine wear
  • Resists oxidation and viscosity breakdown
  • Helps control soot-related oil thickening
  • Helps maintain engine cleanliness
  • Protects under heavy loads and high temperatures
  • Provides dependable cold-temperature oil flow
  • Helps minimize oil consumption
  • Supports long engine and equipment life
  • Helps reduce maintenance costs and downtime

Consequently, AMSOIL synthetic diesel oil is well suited for demanding on-road and off-road applications.

Advanced Wear Protection Under Heavy Loads

Diesel engines used for towing, hauling and commercial work frequently operate under heavy loads. These conditions increase pressure on bearings, cylinder liners and other internal components.

AMSOIL synthetic technology creates a durable lubricating film between moving components. This film helps reduce metal-to-metal contact and provides dependable protection when engines are working hard.

In third-party testing, select AMSOIL diesel formulations have demonstrated significantly greater wear protection than applicable industry test requirements.

Better wear control can help protect critical components, maximize equipment life and keep diesel engines operating reliably.

Helps Keep Turbochargers Clean

Turbochargers operate under some of the most severe conditions inside a modern diesel engine. Extreme temperatures can cause lower-quality oils to oxidize and create deposits.

For that reason, turbocharged engines benefit from an oil with excellent resistance to heat and oxidation.

AMSOIL synthetic diesel oils are formulated to resist deposit formation in high-temperature environments. In applicable testing, select AMSOIL formulations have demonstrated up to 60% better turbo cleanliness.

Cleaner turbocharger components can help maintain dependable performance while protecting an expensive and important part of your diesel engine.

Maintains Viscosity and Controls Soot

Oil must maintain the correct viscosity to provide reliable engine protection. However, soot contamination, extreme temperatures and extended operation can cause lower-quality diesel oils to thicken or lose their protective properties.

AMSOIL Heavy-Duty Diesel Engine Oil provides excellent viscosity control.

Benefits include:

  • Resists oxidation and oil thickening
  • Helps manage soot contamination
  • Maintains a strong lubricating film
  • Protects during high-temperature operation
  • Helps minimize excessive oil consumption
  • Maintains dependable protection throughout demanding service

Therefore, AMSOIL helps protect your engine whether you're driving across the country, towing a heavy trailer or operating equipment throughout a long workday.

Extreme-Temperature Diesel Engine Protection

Diesel engines don't always operate under ideal conditions. Work trucks and equipment may experience freezing winter starts, extreme summer heat or both.

AMSOIL synthetic technology provides dependable performance across a wide range of temperatures.

Protection in Extreme Heat

High temperatures accelerate oil oxidation and can contribute to deposits, viscosity changes and increased oil consumption.

AMSOIL synthetic base oils provide excellent resistance to thermal breakdown and oxidation. As a result, the oil continues protecting critical components when engines operate under heavy loads and high temperatures.

Faster Oil Flow During Cold Starts

Cold temperatures cause motor oil to thicken. When this happens, oil can take longer to circulate through the engine during startup.

AMSOIL synthetic diesel oils maintain excellent low-temperature fluidity. Therefore, oil can circulate quickly to critical components for dependable protection during cold starts.
