RE: Cummins ISX engine oil?

15w40 is fine to run in it. The newer 10w30 is ok also but if you want the longevity of your engine I would stick with 15w40. The small bump in MPG you gain with the lighter oil will cost you in premature engine wear. Remember, Cummins will recommend whatever will get the Engine past it's warranty period. They couldn't care how long it lasts past that point.
