After current blotter spot test, some 100 mL of graphited engine oil in Elf Molygraphite 15W50 is added for its friction-reducing additives.
48 hour blotters,

Comments to follow....
Ok, the centre zone of this 8,784 km M1 0W40 is a bit grayish but remains transparent and not darkened yet indicating a moderate level of heavy and/or big sized contaminants and dirts is present.
Aureole zone/perimeter ring is not darkened but merged nicely such one cannot visually 'see' the demarcation between centre zone vs aureole zone vs diffusion zone, i.e 'structures' are kind of not formed.
It indicates the contaminants are very well spread out from centre zone and it has not begun agglomeration and thus is good news.
Diffusion zone (of inner half) is slightly grayish but remains transparent. The outer part of diffusion zone looks like a clean annulus indicating very negligible amount of dirt contaminants.
The jagged edge has begun to darken a bit indicating water moisture content seems to be building up, but no harm for now imho.
There may be a very faint shadow of translucent halo at the outermost zone .....
possibly very light level of fuel dilution IDK. How I wish inter-state travel balik kampung is not prohibited under current mco , so that this fuel thing may be 'evaporated' off with a high rpm drive of an hour or more.
Overall I'm of the opinion this M1 0W40 at 8,784 kms is fit for continuing service and remains good to go.
Note: These current blotters at 8,784 km contains purely M1 0W40 oil .
The 100 ml of so of Elf Molygraphite 15W50 is today added on for its friction-reducing additives as a 'top up'.
Note2: The dark black dots in the centres of the blotter spots are probably caused by dipstick ends in contact with the A4 paper whilst taking sample.

Oil Life : 11,080 km
8 months oil life .
ODO :325,093 km in
Car model: 2007 Toyota Avanza 1.3L
Engine: K3VE Multi Port Injection
Make up oil added : Nil, but dipstick level drops a little bit.
Added some 100 mL of graphited engine oil in Elf Molygraphite 15W50 at ODO 323k km 2 months ago.
48 hour blotters,
With additional 2300 ish km travelled, previous evaluation on 2 months ago more or less Still applies in current blotter spot test.
Centre zone is transparent not darkened, absence of darkened aureole zone/perimeter, diffusion zone is transparent, some moisture signs and very very light fuel dilution halo, as like before.
No indication of commencement of agglomeration of dirt particles.
Detergency and Dispersancy properties are still performing as it should.
Imho, this 11,080 km used oil is still fit for continuing service and hence, keep going ..............
