There seems to be a belief out there that Cummins is a far superior engine compared to all others. What a lot of people don’t take into consideration is that Cummins has a lot of deferent engines and levels of quality. While some of their engines are really good such as the aforementioned signature series most are just well nothing really to write home about. This is just normal business practice you have a deluxe, standard, and an economy line (guess which one Dodge uses). Cummins has just done a great job in marketing in getting people to associate their deluxe line’s quality with all their engines. In short it’s not really very accurate saying that a Cummins engine no matter what series is superior. It would be like saying every Ford product ever made was superior compared with all other automobiles. You would then need to explain the Pinto. Just to answer the original poster’s question No, No, and No.
