When I had my '11 Ram with a 5.7, I used Amsoil. I even installed a bypass system. Used the 25K oil and filters. Changed everything at 20K. Just cause.
Been using Amsoil since the '70's. First car to use it was a Honda CVCC. Had to adjust the lifters every 10K miles and was always amazed at how clean the valve train was.
Now in my Ram 6.7 Cummins. Oil, oil filter and both fuel filters are changed every 15K.
