Outstanding Engine Protection – Dexos D 0W-20

Wear on camshaft lobes can negatively impact valve timing, leading to loss of horsepower and fuel economy. AMSOIL’s Dexos D 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 is proof AMSOIL’s 100% Synthetic 0W-20 Oil delivers up to 6X more wear protection than required. You will  maximize vehicle life and reduce maintenance costs and downtime.

AMSOIL 0W-20 Dexos D Viscosity Control

Formulated with advanced synthetic base oils and detergent/dispersant additives, AMSOIL Dexos D 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 (Meets Dexos D) 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.

0W-20 DexosD 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.

0W-20 Diesel oil

By  JASON,  a  Verified Buyer  on  May 03, 2024
Got a new Silverado with the 3.0 Duramax and did the first oil change with the Amsoil 0w-20 diesel oil and noticed a huge difference. Truck ran nice and smooth as expected from Amsoil. I have used Amsoil for years and won’t use anything else !

Recommend this product

By  IAN,  a  Verified Buyer  from  Ontario, Canada   on  April 19, 2024
Great oil, cheaper than the competitors at least here in Canada .. been using since my truck was new..

hard to find and amsoil takes care of me

By  G DAVID,  a  Verified Buyer  on  March 17, 2024
I recently purchase this new 3.0 I6 Duramax. Chevy is very particular on what oil is used. My local dealer did not even carry it. AMSOIL did. 3rd oil change in 15000 miles. I dont know if AMSOIL helps the fuel mileage but it does not hurt it! 28.2mpg overall since I bought truck. I have been changing the oil myself. AMSOIL in my new Silverado 1500 diesel. Convenience of shipping, seems to work great. Im brand driven so Ill be sticking with it.

Only oil to run

By  GARY,  a  Verified Buyer  from  Dauphin island  on  May 16, 2023
This is the only oil I will ever run in my new 3.0 gm diesel

3.0 LM2

By  Austin,  a  Verified Buyer  on  June 24, 2023

Highly recommend over other Dexos D gm approved oils for 3.0 duramax. This oil improves your fuel economy by about 3mpg compared to Acdelco oil or the green oil from Mobil 1.

Quiet Now

By  GERRY,  a  Verified Buyer  from  California  on  August 23, 2023

Maybe it’s just me and my imagination, but my 2020 Chevy 1500 diesel seems quieter with this oil. This truck is already quiet, but this oil makes it sound like I’m driving a gas truck. Your experience may vary. LOL


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.

Oil Samples

By  Timothy,  a  Verified Buyer  from  North Carolina  on  May 10, 2023

I have used OEM oil and Amsoil and compared the oil with oil sampling. The Amsoil consistently comes in with less wear metals than the OEM oil.


Better than all… viscosity

By  FRANK,  a  Verified Buyer  from  Idaho  on  September 11, 2022

Viscosity in all situations is better, engine runs more consistent regardless of temperature. Lubricity is excellent also. Surpasses AC Delco requirements for Duramax 2022.
