That '92 would be a first generation Cummins with a mechanical VE pump + mechanical injectors. No Edge or chip or anything else aside from tuning with a few wrenches.

Met a guy recently running his 92 Dodge cummins on a 50/50 blend of motor oil & diesel. Had a pump, tank & filter in bed of pickup. Sucked up any oil he could get and it was filtered and run to the bed tank. This oil was then filtered through a one micron filter and blended to 50% in his fuel tank. The Dodge ran good. He also had an Edge chip and sure could put out some smoke.
Bingo.
Depending on whether you have a VE pump or a P pump in that 4BT, I'd stick to B5-B20.
At these concentrations, you'll have an excellent lubricant & cleaner already blended into your diesel. Add an anti gel additive during winter, as bio likes to gel a bit quicker than #2; though, most places that sell bio reduce the concentration at the pump during winter. Change your fuel filter every couple thousand miles initially, even B2 has a propensity to REALLY clean accumulated slime from your tank.
Use a bit of biocide in your tank every Fall, especially with biodiesel - it loves to grow algae, due to it's love for water.
If you're planning to add used motor oil to the tank, no more than a quart per 40 gallons; and clean your lift pump screen religiously every so often.

I've been debating buying a bio setup but grease seems hard to find with local biofuel places buying it up. Black diesel seems interesting. I usually have plenty used oil laying around.
Don't know if I would put more than 10-20% in the CRD. I am putting a Cummins 4BTAA in my Land Cruiser and plan on running that at a higher % of some sort of bio.
A truly excellent way to cause deposits to form on your injector nozzles, so, NOT. This was done strictly with mechanical injectors & non detergent ATF back in the day.

If you can use transmission fluid or hydraulic fluid. Same results but thinner oil to start with when mixing with diesel.
