Yes. Many oil fills with DT40 and DI40 with used oil analysis after each drain.
I consulted by email with Lake Speed Jr (Driven oil tech specialist) before I changed to DI40 to make sure it was appropriate for the heavy track use I was doing at the time along with daily street driving.
He recommended I switch from DT40 to DI40.

I do. One oil analysis on the books so far after around 4k miles and I think 6 track weekends. I did more events than I intended on it, but life happens. analysis came back good with the recommendation to try a longer interval. I'm sure other quality oils would hold up similarly, but who knows. I plan to keep using it.
