Yeah I will be datalogging the oil temps and keeping an eye on it for sure. Oil temps are broadcast through OBD via a custom PID which is a lot nicer than running a gauge and having to watch it all the time.
Though honestly I don't think it should be a problem. The BRZ/FRS community has been invaded by parts hockers who just convince kids to dump tons of money into the cars and it appears that was where this "must have oil cooler" stuff came from on the forums.
270 is about the highest Ive heard of a stock car doing which is nothing for Mobil 1. I also went to 5w30 which is a touch heavier but still within factory spec.
The oil itself can handle 500 degrees with no degradation (according to Mobil engineers) so its the oil pressure drop that you have to worry about the most.
Since oil coolers also cause an oil pressure drop, often times you are ending up at the same oil pressure as you would have anyway without one.
