I may have spoken too soon. Temps are significantly higher with redline oil even though redline is smoother. Pennzoil Ultra plantinum seems to keep the car 10-12 degrees cooler. I did my usual "abuse run" and the temps were 225 after it all...I would really have to punish the car to get 220ish before.
