    Great Stuff!
    By  JOE,  a  Verified Buyer  from  Texas  on  September 03, 2021

    Describe the issue

    Been using the 2oz for 5gal process for 2 tankfuls about 48 gallons. My mpg went up 2miles per gallon and my horsepower increased. Was having a low rail pressure code P0087 when towing so far I have not had the code since using Amsoil. The Amsoil was suggested to me by a dealership service manager, saying do this for 6 months instead of spending 3 grand on a high pressure pump. So far I have had very good luck with Amsoil. My 3/4 GMC has 170k miles on the engine. My hope is that Amsoil will buy me some more time. I am happy with the results.
    Bottom Line
    Yes, I would recommend this to a friend.
