Regarding this statement from JFP in PA about installing a 160 degree thermostat;

"9. Does it increase performance? The correct answer would be “Damned if I know.” We have heard of slight gas mileage increases after doing this, but currently have not data to confirm or deny that. Should it increase oil and engine life expectancy? My response would be “Definitely.” Cooling the engine, and in particular the oil, is “a good thing”…………"

If that were true don't you think the mechanical engineers at Porsche would know this and install a 160 thermostat at the factory? They don't because for the engine to be "efficient" it needs to run at the OEM spec temp. I think Porsche has a little more knowledge in this field (almost 80 years) than most.

You have a 7 year old car with 62k on the clock, your problem is ether dirty radiators or your pump is going tits up.
