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.

    Reward points
    By  DAN,  a  Verified Buyer  from  Horseheads NY  on  April 30, 2024
    I recently placed this order and tried to use the credit I had on my account before it expired. Bottom line I got no credit nor a response when I emailed about this. Great product but I suggest don’t offer rewards if you have no intention to deliver.
    Bottom Line
    Yes, I would recommend this to a friend.

    The best choice for my 1998 SC2 with Flat Hydraulic Lifters
    By  SYDNEY,  a  Verified Buyer  from  10-percent Ethanol, Michigan, U.S.A.  on  February 11, 2024
    This is my first time purchasing this formulation. For 10 years, I used 5W-30 HD Diesel. The S-Series has a potential for scorched oil scraper rings, so using a better oil is the solution. Like clockwork, the 260,000-mile, 36 mpg highway engine uses just under a quart of oil in the 3000-mile OCI. I trust that this AmsOil Diesel has the anti-wear properties good enough for the high-mile flat hydraulic lifters and the high-mile rocking pistons while I'm keeping-up with highway traffic.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  MIKE,  a  Verified Buyer  from  Michigan   on  January 08, 2024
    I have found that Amsoil has quieted my gmc 2.8L and has made it run very smoothly. The first time I tried it I was astonished at how much better it ran. I will always be using Amsoil in my products.
    Bottom Line
    Yes, I would recommend this to a friend.

    2.8 duramax
    By  JARRED,  a  Verified Buyer  from  Colorado  on  September 21, 2023
    Best oil I’ve tried for 2.8 duramax. It seems to run a lot quieter I’ve been very pleased with it. Only thing I wish they sold a 5quart jug instead of having to buy the single quarts
    Bottom Line
    Yes, I would recommend this to a friend.
