I have a personal experience to share that doesn't amount to anything... in the past I have sent in oil samples from my personal track cars and motorbikes, I was getting reports that the oil was still good, but I changed it anyway, perhaps it was placebo effect but the engines seem to run a little bit quieter and a little bit more peppy after the oil was changed. And perhaps it might had to do with how the aged hydraulic lifters in those particular engines reacted to seasoned oil that's still considered good. Like said before I suffer from being overly concerned about almost everything.

I change mine every 4 track days. I have an initial baseline from Blackstone labs, but after this weekend at Sebring, I'm due for another oil change and will send in another sample.

I ran at Thunderhill in close to 100 degree heat and saw 226 engine coolant temp and 278 oil temp. I have a stock 2014 C2S. I usually only see the 195 coolant temp and was surprised to see the 226 only because I've heard it only shows195 unless the car is close to overheating. Does the coolant temp ever read an accurate number?

I have tracked regularly both a 2014 and a 2016 Carrera, no center radiator with your engine. I also used a data logger. The temps I consistently saw were between 250 and 260, these were PCM temps. They were corroborated by data logger connected to the ECU. I now track a 2016 GT3 and am in shock at how low the temps are in comparison with the center radiator.
