synthetic oils

Please tell me if I have been told wrong. A diesel tech at the local Ford dealership here told me the 6.4 comes from the factory with synthetic oil. He says thats all they use for them. Was he just appeasing me? or lying straight out? some of his reasons sounded good, but cant find any definitive proof. Thanks in advance

rednek, I'm planning to do the same thing and possibily include installing a by pass oil filtration system as well. I'll wait until I get my free oil change @5000 miles though like you. It's said the engine needs the friction to set. So no sythetic until after 10,000 miles.
ssharber: I checked with two different local dealers here in Vancouver, BC. I was told by both that the 10W-30 viscosity CJ-4 oil is used by Ford here, XO-10W30-OSD, part number. It's in a red plastic bottle.
Another issue is that the add level on the Engine Coolant Expansion Tank is too high so coolant has been bubbling out of my Expansion Tank. The Diesel Tech told me Ford should have set it lower on the tank and there will likley be some sort of adjustment coming to deal with this as it's common on most 6.4's. Has anyone else here noticed this problem?

PS I own 18 wheelers and Cummins and Detroit also say nothing but CJ4 in the new engines.

i has used amsoil for years, and i will most likely use their 5w40. i have used mobil 1 and castrol syntec in gas engines with good success. until the oils are rated cj4, i think i am going to use amsoil, if the are any problems with the engine i can bring them the bottle and prove it is cj4.

The Amsoil 5W-40 oil is Not "API CJ-4 Certified", in fact it is Not "API Certified" at all, contrary to what Amsoil would like you to believe.
Amsoil only has 1 "API Certified" diesel oil and that is the 15W-40 CI-4+ PCO semi-synthetic.

If an oil is "API Certified" then it will carry the "API Certification Mark (known as the "Starburst") and the API Service Symbol (known as the "Donut")".

Also Royal Purple does Not have an "API CJ-4 Certified" oil. All Royal Purple diesel oils are only CI-4+ rated

As for Mobil 1, Standard Mobil 1 Trubo Diesel Truck 5W-40 and Mobil Delvac 1 5W-40 are only API CI-4+ Certified.
It appears that "Mobil 1 5W-40 ESP" has obtained "API CJ-4 Certification", however it is just becoming available on the market and may be difficult to locate for awhile.

Hope this helps
