    Great Diesel Oil

    This oil is the finest quality I have ever run into. That is why it is in all our Diesel trucks.

    Best oil for emission sensitive vehicles
    By  Richard,  a  Verified Buyer  on  October 23, 2019
    Use on my stock 2012 duramax with over 100,000 miles. No issues with dpf or other emission systems. With oil analysis, it holds up great for around 15,000 miles.

    Definitely recommend Amsoil over any other brand
    By  Michael,  a  Verified Buyer  on  October 11, 2019
    I travel a lot fishing bass tournaments all over the country pulling a 21 foot bass boat and I immediately noticed a difference when I started using Amsoil in my Ram 2500 diesel. Engine runs quieter and smoother. Can't say enough good things about Amsoil products.

    Good stuff right here
    By  Matt,  a  Verified Buyer  on  October 08, 2019
    I watch my oils pretty close when buying brands. Amsoil Max Duty has the highest rating in wear tests. Seeing as how I plan to keep my truck for many years, this is my oil of choice.

    Long Distance Insurance Policy
    By  Donald,  a  Verified Buyer  on  October 03, 2019
    Have a 2014 Ram Ecodiesel...they have known bearing defects. Use Amsoil to reduce the likelihood I'll need a new engine.
