This. You can mix oils but the pressure you get (well that I got) with 0w20 makes it pointless IMO. The very little MPG increase isn't worth the effort of changing it just for track days, and then swapping back.
I change my fluid on cars I track and lower OCIs so the oil in the cooler doesn't concern me much.
