I was watching a popular YouTube dyno channel the other day and I was a bit stunned when he said he didn’t monitor oil temp because it didn’t matter.

I can’t unequivocally that’s not true. Oil temp affects power output.
10 degrees hotter oil temps from 170 to 180 was a 15 HP loss every time on the Dyno. (My junk engine)
It matters!!
