    Diesel Oil Review
    By  DAVID,  a  Verified Buyer  from  Oklahoma City  on  February 07, 2024
    I use this oil in my 2002 Ford 7.3 Powerstroke. I like the oil. My only issue is it take a full four gallons to get 15 quarts. I didn’t have that issue when using Rotella. Always had a quart left over.
    Bottom Line
    Yes, I would recommend this to a friend.
