I got the info from the 1977 911s Porsche owners manual. On page 21 it says,
The oil temperature gauge registers degrees Farenheit, the oil temperature should not exceed 300 degrees F (150 degrees C) If the temperature should exceed the limit, stop, check the oil level or, if necessary, consult your authorized dealer. 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.
