Product Overview

Synthetic Diesel Oil SAE 0W-20



See the Product Data Bulletin for full details.

AMSOIL 100% Synthetic Diesel Oil is specifically formulated to protect the efficient diesel power of American diesel pickups, vans, cars and SUVs, giving you the edge to keep your vehicle operating at peak performance. It delivers outstanding value and excellent protection for customers seeking an upgrade over conventional, synthetic-blend or competing synthetic diesel oils.

Outstanding Engine Protection

Wear on camshaft lobes can negatively impact valve timing, leading to loss of horsepower and fuel economy. AMSOIL Synthetic Diesel Oil’s strong fluid film keeps metal surfaces separated, while its robust anti-wear additives further reduce wear in metal-to-metal contact regions for maximum engine life. Third-party testing shows AMSOIL 100% Synthetic Diesel Oil delivers up to 6X more wear protection than required by a leading industry standard,1 helping maximize vehicle life and reduce maintenance costs and downtime.

Viscosity Control

Formulated with advanced synthetic base oils and detergent/dispersant additives, AMSOIL 100% Synthetic Diesel Oil minimizes viscosity change while keeping soot particles suspended independently, helping prevent the formation of larger, wear-causing particles. Lower volatility also helps in retaining its viscosity after high-temperature service for added engine protection and increased fuel economy.

Excels in Extreme Temperatures

AMSOIL 100% Synthetic Diesel Oil 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 Synthetic Diesel Oil also flows dependably in cold temperatures for easier startup and improved engine protection.

Minimizes Oil Consumption

AMSOIL 100% Synthetic Diesel Oil has low volatility (burn-off), reducing oil consumption during operation and passing less oil vapor into the combustion chamber. It is safe for diesel emissions systems.

    Baby Diesel
    By  CHAD,  a  Verified Buyer  on  June 08, 2023
    Great stuff that out performs OEM oil. My truck has been running great with no issues and my fuel economy has been around 28 mpg but if I grandpa drive it’s 36 mpg. Thanks amsoil and you have a great crew at the Arlington TX warehouse. They are all extremely nice and always quick to put my order together. Someone needs to fly out and take those boys to lunch.
    Bottom Line
    Yes, I would recommend this to a friend.
