Far too new here to be any kind of worthy source to believe, but I've been around diesels nearly all my life. My dad was a track mechanic in the Army, (Vietnam era). (Which is why I went Navy and then USAF for myself)
Filtering is the primary pass fail point of anything you use. Road diesel can cause just as many problems as old motor oil or gear oil if left to sit and seperate or collect water. The worst thing for an injection pump to live on is water and sludge. WMO if filtered to the level of a small micron filter is the minimum for me. I use an actual water seperator and a centrifuge to spin the metals and other contaminants out of it.
Vegetable based oils wil work, but if you run too high of a ratio of it, you risk varnishing the internals of the injection pump, (I've rebuilt enough to see it first hand, it is very hard to clean off the needles and internals. You won't see the effect in the short term, but if you repeatedly run it, it is going to build up and leave a very labor intensive repair ahead of you.
I deal primarily with Cummins B series engines, not a fan of Dodge, I discard the truck and keep the engines for something worthy of it, like a Super duty or a Jeep. (I currently have a 4BT powered super duty, alas the username destroked).
The biggest thing I've noticed over the years is, the older the engine design is, the more tolerant it is to various fuel types. The more engineers tighten things up and build electronics into the fuel systems, the higher the failure rate becomes. I've run old Perkins on black diesel for several harvest seasons without so much as a seal failure, part of the appeal of a dinosaur aged engine to me.
I stay away from synthetics, transmission fluid and anything ratio'ed more than 60% vegetable base. A close friend of mine has been running his P7100 pumped 5.9 Cummins on 50/50 diesel and WMO filtered with a centrifuge and 5 micron filter for 5 years now, the final fuel product he puts in the tank is spotless, so keep that in mind before you grab a pain strainer and think you've caught all the debris or sludge & water. Condensation effects any container with a vent.
