![]() How "fresh" is the oil? As the miles accumulate oil gets diluted with water and unburned gasoline, mostly water, and these contaminants work to lower the oil's viscosity which can result in lower than "normal" oil pressure under some conditions. that could arise from too low an oil pressure - there is nothing to worry about. (Like the coolant temperature gage the oil pressure gage is not a precision instrument, so that "1.0" bar may be something else.) But assuming it is 1.0 bar, that's 14.5 psi and absent any signs of distress - like knocking, loud ticking, etc. About all it is good for is knowing the engine is cold, getting warm, or warm.Īs for the oil pressure 1.0 bar is not that low at hot idle. The dash gage is not a very good instrument for precisely monitoring engine coolant temperature. This proved to be the case as this happened years ago - circa 2003/2004 - and here it is 2015 and the car/engine is just fine (with over 292K miles on the engine now). The word back from the factory was with no warning lights there was no problem. The SM took the info down and submitted it to the factory. Anything wrong with this?On a road trip which took me into southern AZ in July and after experiencing some extremely high ambient temperature (116F) driving conditions in my 2002 Boxster with intake air temperature running 130F+ and coolant temperature "pegged" at 226F for several hours driving in this ungodly heat afterwards back home I checked in with my local Porsche dealer. ![]() When I switch to N gear level it goes to 1.5bar. While driving on a highway its about 80-85 celsius degrees.Īlso. ![]() This is used to be the coolant temperature during summer (city cruise). ![]()
