My concern is that Southern California has not yet hit its hot season. To me this will be the real test in real-world stop-n-go situations. I have not reached the level of comfort that this issue is over.
I have looked at the engine oil lubrication diagram in the Nissan 370Z Service Manual and it looks like (although I have not substantiated this) the oil temperature sending unit is taking its reading off the oil pulled for the oil pan. My concern is that the VVEL top-end is where the oil gets the hottest and pushed to its limits, and where a better oil temperature reading would be beneficial.
