Which do you consider worse: 130C (266F) indicated oil temp, stabilized and never going into runaway, or losing 30psi oil pressure at, what, 115C (240F)?
I've never thought an oil cooler was necessary, and the more I've looked into it the more I think the negatives outweigh the "positives" which are debatable... More cost, more weight, more potential failure points (leaks are common), and in some cases -30psi oil pressure? Damn...
You may know more than I but I've heard that the reported oil [edit]temperature to the canbus is a calculated, estimated "max", and 275F reported correlates to 255F sump temp which I think is what people have historically gone by for oil temps. I know that's the case with C6 Corvette, reported oil temp is calculated, and it doesn't go into "limp" mode until calculated/reported 160C (320F) oil temp!
I think there's a reason the FT86 goes all the way up to 340F, with 270F being at like 2/3 the range.
