I don't think I would run the 15w-50 just cause at operating temp it might be a little thick for the HPOP

I thought this was a diesel forum?:w2: Anyways I prefer rotella t but dont want to conflict with any international relations while buying my motor oil:argh:

I'm glad I read this, i used to think rotella was the best. Last oil change I got dello 400 le because of the stamp on the front, stating it rivaled synthetic. I have seen that mystic stuff at tractor supply and thought it was a cheap off brand oil. Ill try that stuff next time. Thanks guys.

PS.. you can run 15w50 just fine, your truck would love it especially if you tow or have a heavy foot. The 7.3 ain't too hard, the 6.0 would sheer it much faster.
I am sure I could run it and the film strength of a 50 weight sounds nice on the rotating assembly but might be a little thick in the rails for me. I think I will stick to a 10w-30 in the winter and 15w-40 in the summer. :tu: I don't have a heavy foot and I only tow a few times a year, the truck really gets worked during snow storms and that is about it. |

But for the money and the colder weather performance T5 10w-30 CCV was pretty close for like 6 bucks less a gallon so I went with that.
The 7.3 is pretty easy on oil, not like the cummins is, but have you considered running an oil that is a heavier weight at temperature? Whether it be a 5w40 (synthetic) or a 10w40. A 10w40 diesel oil would give you the same cold-start performance with added film strength. I understand there are a lot of guys running 10w30 these days, especially in the 6.0L (it likes to sheer oil down to 30w) but starting with a 30w would make me a little nervous. The oil analysis reports on Rotella 10w30 look really great, but with such a heavy rotating assembly a *w40 oil would give me peace of mind. :hellox: |

Very true.. it does cost a premium.
