Mind elaborating whether sample was taken while cold or after driving for x minutes or x km ?
I normally take sample within say, 20 minutes of shutting off engine which had been driven for 30 minutes or more while it's still hot for cosnsistency.

Tentatively speaking, I won't be planning for an oil change base on this 4 hour picture for the next one week or so as it appears good .......
However I personally prefer to compare/evaluate picture(s) 48 hrs or 72 hrs after sampling , for better consistency.

Drive the car for about 3mins and waited for around 10mins before taking the sample.

Plan to change the oil today as i'm free but mostly because will be travelling out station next week and won't be free till god knows when.
Really glad to know that this eo is doing the job.

Just call Drex to help with these stuffs

Please proceed with your plan at a time and/or OCI km that's convenient to you and, most importantly that you as owner feel comfortable and happy to do , Senscents.

Coming back to your 24/48 hr blotter spot test pictures shared here, my interpretation is :
a) there is no indication of high level of contaminations/wear particles/oxidation etc ;
b) dispersancy capability is still good and showing no sign of breakdown of oil dispersancy ; and
c) there is no sign of fuel dilution even though this blotter sample was taken 3 minutes after engine shut down at relatively lower/colder oil temperature.

A) Comparing this blotter against that of Formula Shell 5W30 (FS*), my vote goes to current blotter.

Edit:3 minutes after shut down .... be amended to : 3 minutes of driving.
Edit:Add '48' to 24 (hr)

72 Hrs Blotter

Wow, nice blotter at 9900 km.
Is your drained oil looks amber coloured and/or goldenish colour ?
Am I right to speculate it's not dark gray colour ?
Refill with what oil in this 2014 Perodua 1.3L ? Pennzoil Velocity ?

72 hr blotter



Looks ok at 10,616 km ....... and going.

zeng
Would like to seek your opinion on my engine oil status.
Brand: some cheap unknown fully synthetic tortoise brand bought from Singapore which meets VW and MB standards

In use since May 2017 and mileage is 7000km now. Main concern is frequent short journeys performed, sometimes less than 3km.

Mushigen, thanks for uploading the 7000 km blotter spot test.

The 2 hour blotter is real impressive, but I believe 48 or 72 hrs ones are more reliable and consistent.

The 48 hour blotter spot does not show any centre zone (normally about 6-8 mm size in diameter ) which is oil drop zone, indicating oil detergency and dispersancy is in tip-top condition.Absence of opaque center zone is a good indication of serviceable oil condition.

You may uploade another 72 or 96 hr Blotter spot to confirm the absence/presence of 'centre zone', if any.
If there is a centre zone, whether it is large size and is shrinking to smaller size, and whether is dark coloured or light coloured , and whether is transparent or opaque.
However , there is some dark coloured or light black scattered dots indicating carbon/combustion products or soot particles possibly caused by frequent cold running engine with 3 km (severe duty) which overall is considered very mild.

This oil is still serviceable and you may continue with this same oil , by 8500-9000 km take another blotter spot for assessment.
If you'd replace the oil, in future the OCI of similar oil brand may be extended to 10,000 km and evaluate further.

Note:If your oil has MB 229.5 and VW 50200 50500 approvals, then this is among one of the top oils in this region (though the brand is unknown for now), which I believe 10000-15000 km OCI is no sweat really. Unfortunately there is no further details from you.
If it has MB 229.3, it's as good though weaker than a MB 229.5 .

Btw, what's the car and model number, Model Year and km ?

JMHO.

Car is 2004 Vios first gen, mileage 140,000km - yes, true low mileage cars really do exist although not everyone knows frequent short trips are not good for engine oil.

72hr spot.


The el-cheapo engine oil, it has only MB229.3 approval though.


Not sure if it matters, but I also did blotter test for a cold engine oil on the same day.

Yep, your latest 72 hr Blotter Spot Test confirms the 'absence' of centre zone (which is good news) and hence the oil's capability is still good and intact.

It also indicates contaminants/insolubles( from some dark grey scattered spots) as mild and acceptable.
I consider this 7000 km used oil as fit for continuing service.

Taking blotter test in a cold engine tends to show up 'presence' of fuel dilution ( observe the outermost band of colourless light band surrounding the coloured zones) which may not be representative of the hot engine oil sample.

Your cold sample shows signs of fuel dilultion, which may not be valid with a hot sample in most cases.
But your hot sample also shows signs of fuel dilution which I consider as definitive, in relation to a cold sample,
that there is fuel dilution issue in the oil ...... as confirmed by the hot engine oil blotter spot test.

Of course some may argue that UOA is required for confirmation of fuel dilution.

Edit: Oops, by hot I meant the engine was operating for at least say, 20-30 minutes prior to taking blotter sample.

Good thread.

I have always had long oil change intervals.


I'm currently on 15k on semi 10-40 intervals. My car is primarily highway miles.

Nice to know there are fellow kakis pushing semisyn 10W40 to 15k km OCI.
Btw, may I know your engine oil specs/brand and car specs please ?

I used variety of Brands

Castrol Magnatec
Shell Helix
Total Quartz

Or what other flavours I can find from Tesco when on sale.


I'm doing 15k OIC on my 2009 Hyundai Matrix with 200k ++ KM. I do 50k a year on mostly highway. About 4K a month, so its a 3 month interval. Filter is original Kia/Hyundai/Mitsu

Wow, with 50k a year you are a good candidate for 400k-600k km mileage car in time.
Highway miles are in a way easy on oils, in particular when oil viscosity grade is thick enough as like a xW40 in our local ambients.
I believe 15k OCI for Euro oil in 2009 Hyundai Matrix should be ok, but I would exercise caution on non-Euro oil with close monitoring.
Lately 10W40 semisyn Euro oils in Castrol Magnatec and Total Quartz 7000 are hard to come by, but fortunately Helix 7 Euro oil is still easily available.
