This probably DOES NOT qualify as an OIL CHANGE as there was no CHANGE of oil......
2005 Porsche Boxster 2.7 (Mobil 1 0w40, Hengest filter, OCI - once year)
Out: 0.5-6 or so(?) qrt of Mobil 1 0w40
In: NONE
Overfilled by a tiny bit (back in July) and decided to drain by removing the filter / housing (did it twice) - I didn't really care but my friend kept insisting as if my engine was going to blow ;-) Back to the "recommended level."
Would have been nice if there was a fumoto valve like our other vehicles but the car too low
