That shouldn't be an issue as I would assume most heavily tracked cars change the oil after each event weekend (and take an oil sample from time to time and send it to Blackstone or some other oil analysis company).

Yep, I run Redline. Change it before and after every event (from motor oil to racing oil and back again). I even send in oil for analysis...
