After finally using up my stockpile of Rotella-T 15/40 CJ-4 I have to decide what to use. I did try Travellers this time and have just a few hundred miles on it. When it gets near 5K I will send off a sample. There are many oils out there that meet the Ford spec WSS-M2C171-F1 including the Travellers. I am considering Motorcraft as well. I have always used dino in it and would prefer to stick with dino. It is my understanding that in making the new oils DPF safe there were additives that were removed or reduced, but at the same time the oils have to be backwards compatible, so, according to who you listen to, the new oils may not protect the engines as well as the old oils did, since now the big issue for the manufacturers is to make their emissions systems last through the warranty.
I did do a bit of searching so if I missed an older thread about this please point me to it.
