Default Old Case Diesel - need higher viscosity oil recommendation...

Bought my Case 580B about 12 years ago, it's become more of a necessity as I deteriorate (get older) - the engine had (supposedly) been "rebuilt by an out-of-work diesel mechanic as payment for a debt) - I'm pretty sure that "rebuild" was done with a rattle can - dark smoke when pushed, oil level never drops (but DOES change color to dark) - I'm NOT a diesel mechanic (altho I DO occasionally use rattle cans )

I need it to last a couple more years, when I hope to get time (and a dry place) to do a REAL rebuild, but for now it just needs to keep running -

Meantime, I'm looking for best recommendation for a (maybe?) 20W-50 oil instead of the original factory recommendation of Delo 400 SAE 30

Suggestions (SERIOUS ones) please? Steve

Get in touch with shadetreewelder. He is the lube specialist here. Dont know if that is a good thing, bad thing, or a vulgar thing but, from what I gather he is the king of making things slide, rotate, gyrate, vibrate and all that by knowing and using the proper lube! Good luck with it!

MidMo, thanks; I have a ways to go to become an "Ex Spurt", AKA "drip under pressure" about diesel stuff, did wonder about injectors but the black oil makes me wonder if it isn't BOTH (re: "rattle can rebuild")

Cutter, thanks for the reminder; no SPECIFIC jobs for "godzilla" in the immediate future, finished knocking down about 8 5yd "lumps" in one pasture yesterday so the little Allis 160/Gannon box w/top+tilt will take over for that smooth-out job... Steve

I can’t say I’ve seen an older diesel that doesn’t turn the oil black.

If the level isn’t dropping, then it’s not leaking or burning oil IMO.

Black smoke with a diesel usually means incomplete burn.....either too much fuel, or not enough air.

If it was a blueish smoke, especially if the oil is dropping some, then I would say it’s burning oil.

And always start with basic maintenace, check/change air and fuel filters.

All of our older diesel tractors and farm equipment that we have/had, the oil was always almost black when we changed the oil in them. The cleanest oil I have seen when we changed it was from propane powered equipment.

Yes but usually comes along with starting issues or very poor running conditions
blackish with the blue mix is usually always an injector pump issue and is always hard starting or non-starting...
