Synthetic vs Dino Oil ??
Cummins 8.3 ISC Diesel engine. Has about 30,000 miles. Currently has Synthetic oil in it, I assume it's been using synthetic for some time. Need to change the oil. Should I stick with Synthetic or...

One of the great myths of Synthetic oil is "You can't go back".
What the *(@#*$ do you think blended oils like DuraBlend, Max Life ,and so on are? Mixes of synthetic and dino.. You can switch back and forth.
That said. I'd stick with either full synthetic or a blended oil at least.. I run Blended in both my car and MH (Car by request, Motor home because the shop that does my oil changes by default uses blended, I'd use full in it if they had it but the difference is not that great so as to go out and buy my own).
Oh, the kernel of truth in the myth.
ONE early Synthetic, no longer made, did cause switch back issues.. But that was many years before the end of the last century.
