    Default Motor oil.

    Someone help me out. What is a really good oil to run in an old 80's diesel?

    Any non synthetic 15W-40 will work fine.

    Just out of curiosity what are you running? a 6.2 GM? I had the infamous 5.7 Olds diesel DX block in a very clean cutlass. I also ran 15/40 in it. I run 15/40 in my 350 gas truck also, just because its free.
