Im wondering for you guys that go tracking HPDE (circuit),
how often do you change your oil between events?

Im usually changing mine every 2-3, and by the end of it, it is thin and black!! and my car is only 3 months old too

The the N54, your oil will have fuel dilution in as low as just a few hundred miles and black as well.

With a good synthetic, you can go 4-5 track days without changing your oil, but just to be sure, send your oil in for analysis.

With Redline we have been getting away with 5 track days. Doing it after 2 track days was too much and just a waste of money. That is after carefuly reading of the oil analysis results.

We will now switch over to Total and see if there is difference.

Harold - so you did a UOA on the redline after 5 days? What "variable" concerned you such that you decided to change the oil?

I go by both TBN, flash point of the oil and cST and SUS viscosity at 100C and 210F.
