Absence of darkened and opaque centre zone .
Absence of darkened aureole zone / perimeter ring indicating no agglomeration of contaminants , yet .
Diffusion zone darker than before , indicating increased levels of dirt/contaminants/combustion by-products but appears harmless for now .
Darkened jagged external edge indicates presence of moisture in used oil , which is supposed to aggravate corrosion wear .
But centre zone/aureole zone, perimeter ring and diffusion zone do not indicate alarming levels of wear/dirt/contaminants caused by moisture corrossion .
Fuel dilution seems to be absent from blotter sample .
and ....... going , for now .

10 day old blotters ,
Note: For the 1st time , using 'wrong' method of blotter sampling i.e this sample was taken cold after some 12 hours of cooling post engine shut down , instead of supposedly taken hot after >20 minutes of driving .
This 20,183 km used oil was replaced with yet again Mobil 1 New Life 0W40 .
