Improper ignition timing or a slipping V-belt also cause too high oil temperatures
I'm wondering where everyone else is coming up with their figure for too high oil temps.
Schumicat, what's wrong with using Mobil 1? my mechanic is Daniel Jacobs in CT, one of the most well respected Porsche Shops in the Northeast. He uses it in all the 911's he works on.

Most of the "too hot" figures you see quoted on the oil temp threads are simply misguided, emotional reactions to pre-conceived notions of "heat" (probably based on what so-and-so knows about the boiling point of water). I've often read on this forum that 180-185 is the sweet spot and anything over is a cause for concern, and this is just plain false.
