I was reading the link above and the only thing I read about using diesel motor oil in the B58 or any modern gas engine would be early failure of the catalytic converter. Anyone know anymore about this? I am still planning on using a 5w40 diesel oil like rotella t6 or maybe even Amazon basics 5w40 heavy duty diesel oil.

Oil blowby is burnt up in the combustion chamber and exits through the exhaust. It's possible that the additives in diesel oil can clog/damage catalytic converter element.
