I use Amsoil products for all my engines. The boat gets 15w40 heavy duty/marine diesel oil. It had a high TBN of 12. As the acids accumulate in the oil the TBN will diminish towards 0. I send oil samples for analysis. Typically in high compression engines which accumulate a lot of soot/exhaust in the oil, the TBN is the limiting factor as to when the oil is exhausted.
It's cool to trend oil properties over time and be able to understand the changes and what they mean about engine health. Kinda like a blood test for your engine.
