About a month ago i was looking for signs of loss of coolant, since i had to add 2 liters over the summer... tune up revealed everything good, i followed good advise and sent my first sample to blackstone... So i am looking trough the results.... Motor has approx 60K, DD, oil (castrol 5w50) when tested was just under 6k.

"This first sample from your Porsche is a beauty. Universal averages show normal wear levels after about 4,500 miles on the oil. This oil saw more use though metals all read at (or below) universal
averages, so this engine is wearing better than most of its type. The viscosity measured a little low, though
considering how good wear looks, we can't exactly call that a problem. Fuel dilution measured at a trace,
which isn't a problem level at all. In fact, it's probably the harmless result of something like starting the
engine prior to sampling. Nice report!
