I would be interested to see if your dealer would put that in writing without using the words, "in our opinion" or something like that. All the major brands and most of the lesser brands meet the API standards and no one brand has anything over another that is significant to the engine.Dealer said Shell Rotella T 15w 40 is no good they say Ford motorcraft only.
Wow, even going to tell you what brand of fuel to use. Time to get a new dealer. I've been told that some of the synthetic oils have solved some cold weather romp problems with the 6.0 but these people are pulling your chain. I wouldn't trust them to do the repairs even if they have someone smart enough to find the problem.All they say is it is the oil. Have to use Motorcraft oil and run Chevron fuel.
