No need import those fancy and expensive chromatogram paper for lab use.
Just use an ordinary letter-head or telco bills.
Non-glossy 70/80 gm A4 paper from Tesco/Giant also can.

Imagination,
Are you referring to Syntium 500 10W30 SN GF5 as follows , if its website is up to date ?
https://www.mymesra.com.my/Passenger_Car_Mo...500_10W-30.aspx
Otherwise, either website is not updated or your invoice description has error.
Can you upload front and back pictures of the bottle ?

Let's assume for now it is Syntium 500 10W30, SN GF5 , which is having a TBN of 7.0, this oil is still inferior to the
a) Syntium 800 5W30 SN GF5 with TBN 8.5 and ;
b) Syntium 800 10W40 SN A3B3 with TBN 10.0 as already stated above.

With any of the 3 oil types above,No you need not 'follow' the (OEM) suggestion limiting to 6 months interval.
If you wish, you may even exceed 12 months, however Blotter spot test is prudent.

No expiry date really, if you monitor with Blotter spot test regularly.

Yes, no problem stretching it to 10,000 km OCI or exceeding 1 year in particular with Syntium 800 10W40 SN A3B3 above.
But please monitor with Blotter spot test to check for abnormality, if any, during usage.


Without links to product specification , sorry I apologise for not being able to comment on 'Car Doctor' oils as I'm totally clueless about its specifications .
Why not consider branded oils where it has websites with specifications details freely available to general public as there are aplenty in Klang Valley ?
After you have considered its prices/budget and its availability to your locality, then providing me your choices of oil brands and viscoisty grades (with links etc) being considered by you, my dedicated comments subsequently may meet your specific needs better, I suppose.

Generally local mechanics charge you labour cost of around RM10-20, with your own oil, why not consider buying branded oils (like Castrol , Shell, Total, Liqui Moly, Ravenol,Mobil etc ) of high quality that are being sold in Giant,Tesco and Aeon Big outlets throughout the country ......
where they have sales promotion every now and then at real cheap price ?

Hope it helps.

Tq for your valuable comments.
Good to kniw that the EO holding up.
Odometer at around 69k km
Do not know what type of injection.
Will try to have another blotter sample next week.
Here are the 48hrs & 72hrs.

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.
Pennzoil Platinum Velocity 5W40 at 9900 km in Perodua 1.3L 2014 :

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 ?

48 hr blotter

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.
