Anybody using oil analysis of any type with their 997?

I am interested to see what peoples experiences are with this practice of oil sampling, to see if reccomendations of analyst vary with Porsche reccomendations.

I thought that only airplane motors get there oil

checked. Never thought about it for a car. If

the motor fails, you just pull to the side of the road

and replace the motor.

Elemental analysis of engine oil is subjective IF you cannot get the OEM specs for life/concentrations of key elements that make up the engine's moving parts. Silicon, Iron, Chromium, Molybdenum, Aluminum, Magnesium, Boron etc. are very difficult to quantify in an oil analysis if one does not know the empirical make up of the engine wear parts.

Molybdenum from the rings, silicon from the cylinder bores or dirt, chromium from rings and camshafts, iron from pistons, cam chains & drive sprockets.......one needs to know the composition of all the moving/wear surfaces.

So, you can send any sample for analysis - but are the results going to have any real meaning?.....that is the most difficult question to answer without serious OEM involvement. I doubt this kind of information from Porsche is easy to get. You may have better luck talking with a dealer who does oil analysis - do they know of any OEM specs as a reference/guide?
