short answer from that article:
A quality conventional motor oil will tolerate oil sump temperatures of
up to 250 degrees, but starts breaking down over 275 degrees. The

I don't know what Chevrolet was thinking re 280 degrees - maybe that
normal oil change would be ok if it didn't get that hot too long or too
And - you do want to know the hottest temp the oil gets to, 'cause
that's where it will be breaking down, right?
It might also be nice to know the temp going into the bearings, as that
would tell you something, maybe...
