I use Rotella T 5w-40 in my crankcase, b&m synthetic trick shift in my 5 speed, and my p/s pump, my rear axle isn't synthetic yet, but currently has Lucas 85w-140 in it.
Quaker state in the gassers and Delo in the big trucks.
What ever 15w40 is on sale. Lots of Warren oils like super tech and proline as I can get those cheap. I have ran Delvac,Delo too...when on sale. I don't think you can buy a bad diesel oil. I tried a 5w40 synthetic and my engine drank it like it was free.
