Off Topic. But the Matrix is very underrated and misunderstood car, mostly due to how it looks. FWIW, it was designed for the European market so it feels and drives like one of that era. It is underpowered though...which means you try to maintain momentum in the corners.

Handles very good for a car of that type. I will leave it at that.

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.

Alphaz,
Will appreciate your sharing of this high mileage Aisin 5W30 blotter spot tests ....for everybody's knowledge and experience.

Where is the spare part shop exactly? excellent price you got there.....

Sorry to give you another boring and repetitively similar comments ......
that there is absence of center zone in this 11400 km blotter indicating high dispersancy capability of this oil sample .
Generally the other zones are not dark indicating low level of contaminants/combustion byproducts possibly due to cleaner ( Hyundai G4GB ) engine internal conditions and adequate quality of this Aisin 5W30.
If I were you, I would continue using this 11400 km oil and do another blotter spot test in 1500-2000 km and go from there.

This Aisin 5W30 , though 'unbranded' looks quite impressive so far.

If you are still having the container bottle, read the fine prints at the back, or upload picture on back of bottle, to see if it's made in Japan/Singapore/local ?

Sure enough , there is good news in absence of center zone indicating the oil's continuing serveceability.
However at outer most rings, there is some indication of fuel dilution ....... not sure if it's caused by sampling at cold temperatures, or having frequent short trips, or fuel injection matters though.

Yeah, it doesn't make sense to keep used empty engine oil bottle ..

Emm did you guys change the oil filter say every 7-10k km in between?

This 14990 km blotter spot doesn't show up any sign of centre ring or centre zone, indicating detergency and dispersancy capability of the oil is still intact like new, and hence continuing serviceability.

The outer zone is not grey or dark coloured , indicating there is minimal contaminants or 'rubbish' within the oil.

I'm really impressed with the performance of this Aisin 5W30 oil in your Hyundai engine and I would personnally further extend the OCI beyond this mileage .

Btw, do you use solely Euro 4 RON 97 petrol ?
..... as my combination of Avanza 1.3/Total Quartz 7000 Energy 10W40 was solely on BHP RON 95 supposedly Euro 2.

Euro 4 RON 97 here has below 50 ppm sulphur,which is supposed to be 'less' damaging to engine oil life in relation to a typical Euro 2 petrol at 500 ppm sulphur.
I beliveve RON 95 BHP  from a refinery in Singapore are of less than 150 ppm sulphur.
That same Singapore refinery also supplies to Caltex here, I wouldn't be surprised if its sulphur could be low too though I have no facts to support the statements.
Maybe some one can comment if Petron petrol comes from refineries in Singapore.

Not sure if the 150 ppm sulphur in your BHP helps in your blotter spot 'cleanliness' , other than efficacy of Aisin engine oil and engine mechanical conditions.

Good blotter spot test at 10060 km, no sign of centre zone perimeter ring indicating good detergency/dispersancy properties close to as new.
No dark grey dirt/contaminants in centre and intermediate zones,  indicating contaminant levels not very high at this high mileage.
No indication of fuels in outermost perimeter zone.
Engine appears to be in tip top conditions and well maintained.
This oil is still serviceable and could probably go for another 2000 - 4000 km and test.
Did you go on ?

Edit: Apologies for late response, alphaz.
Edit2: I personally consider this 10060 km SHU 5W30 blotter spot as performing relatively better than Honda 0W30 at 3750 km above.
Not trying to bash Honda 0W30 though.
