Excellent oil and it's what I use in my Dodge Cummins truck engine. You should be fine. Wally World usually has it on sale for around $11/gallon.
I used to use Rotella TTT, but the results I was getting back from Blackstone Labs seemed to show that the oil was breaking down fairly quickly and it was showing some engine wear. I switched to Delvac 1300 and the reports are now showing excellent oil stability and reduced metal particles, i.e. less engine wear. So I'm sticking with it.
