Car sees severe service and who knows how long it was in there for. Below is from another thread.

For such a short run, I would have expected better TBN retention. This isn't a forced induction application or an engine that has a reputation for being hard on oil as far as I'm aware. City driving is a factor in many UOA's posted here, and that still, on vehicles with an OLM, tends to lead to OCI's much longer than this one.
Would liked to have seen TAN as well, as I noted earlier.
