Norm: Not sure about your car but for my 2005 996 that would be too high of water temp and too low of oil pressure! I can tell you this year I switched from Mobil 1 0-40 to Joe Gibbs DT40 which is a 5-40 weight oil. Quieted engine and gained about 1/2 bar(just under 2 bar) at idle after warmed up in 90+ temperature. I have read that 1.5 bar warmed up is acceptable to many on these forums.
