The Cummins in the past had a lifetime warranty. This motor was used in other things. Pretty much last forever.
The v-8 is an inferior design. As it is a lot shorter it fits in more vehicles.
On the other hand Ford and Chevrolet make a better truck.
The 6.6 Duramax has evolved but GM hasnít changed diesels ďa lotĒ by any means. Prior to the Duramax their diesels were built by Detroit; 6.2L and 6.5L.
Ford is new to the diesel game with their own 6.7 engine, that is true. Before that they were built by International/Navistar dating back to the 1980s and the 6.9L.
Cummins is my preferred engine, but the Duramax has proven itself to be a very stout and reliable engine since the LBZ.
Hard to argue with engines that have proven themselves regardless of their design or who makes them.
