[QUOTE="01yellercobra, post: 16513650, member: 35549"] FWIW, for the cold start surges try a slightly thinner oil. I was running 15w-40 in my 6.7 during the summer and when the winter months hit I would get cold start surges. These were 30-40 cold starts. Switched back to the recommended 5w-30 (or maybe its 10w-30, I'd have to double check) and its been fine since. It was 38 degrees when I drove to work on Monday. [/QUOTE]
