Do a search and you will find that plenty of people have had problems with leaks. Other issue is that oil is slower to get to operating temp. That "Savagegeese" guy became annoyed with his initial FT86 because he (wrongly IMO) thought he *had* to have an oil cooler, installed one, removed it in the winter because oil didn't get hot enough, and then it leaked when re-installed.

I'm sure you read this from that article "The traditional approach is to try to hold oil temperatures between 230 and 260 degrees".

Here is the context:
https://www.motortrend.com/how-to/en...0260%20degrees.
"A quality
conventional motor oil will tolerate oil
sump temperatures up to 250 degrees, but starts breaking down over 275 degrees. The
traditional approach is to try to hold oil temperatures between 230 and 260 degrees."
They're talking about non-synthetic, and they're talking about oil temperature in the pan.
Regarding synthetic:
"A full-synthetic oil will withstand
sump temperatures
in excess of 300 degrees, and for hardcore professional racing, some oval-track race teams are experimenting with ultra-thin, specially formulated, race-only synthetics operating at 350 degrees or even higher."
