This is the oil analysis for our Renault Koleos (Nissan Xtrail T32 with QR25DE engine)
Serviced with the dealer here in Australia where Castrol RN17 5W30 was used.

Since this was the factory fill, it likely had some assembly lube mixed in. And that could very well be higher viscosity. Nothing suggests the oil has thickened

Not factory fill. 4th oil change, just done at the dealership with "genuine" oil.
