The assumption of the oil minder would almost certainly be designed with the factory oil fill in mind (and assuming you do oil changes at the dealer with factory oil), so any other oil you choose that’s different especially synthetic will not follow the same rules.
The only way to really know the change interval of your oil (how many miles, track days or using multiple cycles of the oil minder) is to send it in for analysis a couple times the analysis comes up as requiring an oil change.
I’m running Amsoil signature series, and I was actually fairly surprised after sending my oil in at 8000 miles, and the analysis came back “plenty of life left, check at next interval” with plenty of additive and low metals contamination. The oil does claim 25,000 miles, so I’m curious at what will actually result.
Haven’t done any track days yet, but I have a short commute and go for weekend drives, so plenty of exercise. I’ll send the analysis in at 16,000 and see what comes up. Also thinking if I do a trackday to get one done before/after to see if I can estimate “equivalent miles” to knock off the interval. Unless you’re running high power, dedicated track car with short life “race” motor oil, it’s questionable whether you actually need to change oil for a recreational track day, and I intend to find out by actual analysis (at $20-50 it’s way cheaper than an extra unnecessary oil change)
