30668 Miles, I am not asking for an oil brand for your preference. I think my dilema has more to do with the fact that I hear quite a bit about the fact that Ford is saying to switch to 10W 30 on the 6.0 for winter. Even if I decide not to use 10W 30 and go with a synthetic I am curious on what the heck there even talking about. The only thing they sell around here for diesels is some synthetics and rotella 15W 40 as far as I know. I see Motorcraft 10W 30 but it clearly says for gasiline engines only and has no CI-4 rating on the back. Oh, and yes I have had the cold start flashabout the same time the changed the oil recommendations for winter.

Thats what I figured, it is at everyone elses Walmarts and auto part stores but not mine here in Colorado. I wonder why? The only thing they have here is 15W-40 and synthetic for Rotella. Thanks AB

Can I mix Rotella 5W-40 Synthetic with 15W-40 Dino just to thin the Dino out?

Don't mix Syn and regular oils! They do not play well together. Use one or the other. If I were you, I would use the 5W-40 due to your location. I use it.
