It's mentioned in the first post and some of my replies. The reason i drained off some oil to begin with, was to add Liqui Moly Ceratec. The boron oxide and moly is part of the antifriction package in ceratec, that supposedly reduces chance of bore scoring, and reduces metal on metal friction.
The oil itself is a porsche A40 rated oil: mobil1 3000 x1, 5w-40.
The viscositie is somewhat compromised by fuel/gas in the oil according to the report.
