Hi alphaz,
I don't see the presence of (dark coloured) centre zone (of about 8 mm diameter), which is good news as it indicates dispersancy of this Aisin 5W30 SN oil at 7400 km in Hyundai G4GB is still robust and not failing.

The grey coloured contaminants/by products is being spread out well indicating oil is performing.

There is also no signs of fuel dilution problem in this Hyundai engine.

I would speculate your intended 10,000 km OCI should not be a problem, IMHO.

Thanks for the analysis, here's the picture taken after 48 hrs:

Total Quartz 7000 Energy 10W40 SL A3B4 blend in Toyota K3VE 1.3L Multi Port Injection,
13478 km , 48 hr blotter ......

.... and going..

Mind asking Mazda 6 diesel owner manual oil type recommendation ?
Asking for ACEA A3B4 ?
Helix Ultra is 5W40 ?
Btw, will wait for a 48 hr blotter spot to see how it's center zone develops ...... meanwhile this diesel engine doesn't appear very sooty, so I suppose it's age is quite new and low in mileage ?

Should be Acea c3

Need to just helix ultra ECT 10 w-30

Mileage 10200km, Honda 0w-20

Is it good to go?

Boxer07 ,I couldn't see any (clear,sharp and opaque) center zone, indicating there isn't much contaminants and oil dispersancy property is in tip top condition, hence this oil is good to go on beyond 10200 km OCI .
You may take another blotter spot test after 1500-2000 km from now, I suppose.

Note:May I ask, what engine model is this ?

Is it

?
...which is VW approved Long Life oil,

or this

?
...which is NOT VW approved.

Btw you have 48 hrs or current blotter spot for clearer image on center zone for evaluation ?

In Malaysia I think they launched the top one

Don't have 48 hours but I remember this is as far as it got

This Helix Ultra ECT C2/C3 0W30 has OEM approvals in VW 50400 50700, MB 229.52 229.51 229.31 .....
that has 30,000 km OCI in Europe VW,

Absence of center zone indicates clean oil with high dispersancy capability ......
I would rate its 10,500 km usage in Mazda6 2.2L diesel could be further extended.
Maybe try another blotter in 1500-2000 km from now.

Honda City 2014. GM6. Non hybrid version

wont go too far to 1500km as i still need to maintain the vehicle warranty . so will go change engine oil tomorrow at SC.

Covered by free service so just service according schedule

Yes, TGMO 0W20 is undeniably a very strong oil with good UOA results such as,

Btw, IIRC all Honda's in USA has factory recommendation of 10,000 miles OCI whilst under warranty , that's equivalent to 16,000 km here.

I completely understand your situation with local SC on warranty matters .... on OCI's beyond 10,000 km.

I would hazard a guess your used oil condition may probably show some 'goldenish' colour and not dark black.
