Does anyone measure their PSRU temperature? So this = is weird, usually it would only be about 2-5degrees hotter than the inlet o= il temperature. That was in Oct.

215 Oil pan

Side note, I did upgrade my oil cooler last week about 40% fin area, to a S= etrab 34 row. Depending how you measure the 'core'. It dropped the = overall temps about 10F, while taking off in 100F weather.
