The Oil Pressure did not vary from stock much at all, at least not an appreciable difference to be of concern, the values were still within BMW specifications of where the oil pressure should be operating.
Oil Temperatures. The temperature of the oil never exceeded 225*F (slightly past the half way point on the cluster gauge) surprisingly. Another fact to note, in a slightly cooler climate at the same track with TWS 10W-60, the car run much hotter oil temps (slightly past the 3rd marking for those who want a reference point). During cool down laps, oil temperature also lowered noticeably faster than they did with the 10W-60.
This M3 will remain on 0W-40 Mobil1 during a hotter event, and will report back once again, however I expect it to be equally impressive in less ideal ambient conditions as well.
