The viscosity is slightly decreased and the oil acidity (TAN) increased. Oil-wetted components health is good.
The oil properties are stabilized, which indicates that the oil has not degraded over the last 2500 km. Oil-wetted components health is good.

Incoherence between oil mileage and oil properties and wear metals levels. Suspect that some usage information may be erroneous. New oil used with high initial acidity (TAN) level due to its formulation may provide miss perception of oil being oxidized. 3 cycles completed

Oil properties and wear metal levels are good. High sand/dirt (Si) level.
The oil properties and oil-wetted components health were tolerable (low level of wear metals) until a possible coolant leak occurred. The oil life extension had no adverse impact on the components. 1 cycle completed.

though the oil is new, it shows low viscosity. High copper (Cu) levels indicate worn bearings and bushings
Suspect that oil change occurred or top up after 70827 km as the oil properties improved and wear metals level decreased. Oil-wetted components health is good.
