UOA Renault Koleos (Nissan QR25DE) 28.9k kms; Castrol oil 5w-30 10k kms

[C5032005]

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.

 

[fantastic]

Like they flagged, the viscosity is high. Thanks for posting your QR25DE UOA.

decent low wear numbers for such a new engine
contamination desirably low (no soot value, though)

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.

Soot may only be measured for diesel engines.

Right, I mixed 2 threads in my mind.

Good engines. DI but not heavy diluters.
