Oil Life :
17,080 km12+ months oil life thus far .
ODO :331,093 km in

Make up oil added :
Yes, about 500 mL (of Shell HX5 15W40) several days before current blotter date.
Oil level seems to drop by about 500 mL.
96 hour blotters,
Comments to follow, next week.The Centre Zone is slightly darkened though not fully darkened, quite transparent and yellowish indicating presence of high-density and heavy combustion dirt particles like metal wear etc.
Good news is, there is absence of emergent darked aureole zone/perimeter ring (of about 10 mm diameter on real sample) indicating agglomeration of dirt contaminants has not commenced, if present.
Inner annulus of Diffusion Zone is a bit darkened/grey but remains sort of transparent and not opaque indicating quite substantial levels/amounts of light-density combustion by-products like contaminants and soot.
Outer annulus of Diffusion Zone remains quite clean, light coloured and transparent indicating the used oil sample's capacity to receive or absorb further quantities of light-density dirts.
The outermost jagged zigzag edge of the blotter is quite fully darkened indicating presence of moisture and substantial oil oxidation phenomenon.
Translucent halo at the outermost zone is absent indicating absence of fuel dilution phenomenon in the engine and oil sample.
As usual, engine coolant contamination is absent.
Imho, there is no cause of alarm or caution in immediate terms but it may be time to plan and schedule the next oil change with this 17,080 km used oil, before or immediately after coming CNY (falling on 1 Feb 2022).
Happy New Year 2022 and CNY in advance, btw.
