Glad that you find this thread useful.
Post #1 has some links for reading, and blotter spot pictures for comparison.
This Syntium 800 10W40 has quite a strong specs,


The blotter would 'mature' at 48 hours or more, and may provide more consistent evaluation, IMHO.
Upload one when you have it for general comments, if you may.

Hmm... so meaning, I take another picture of 48 hours only can comment?

This is SM stated on bottle sticker. And oil comes from Petronas.

Thart's right, a 48/72 hour blotter would look 'different' from a 12 hour one .


Thanks.

Dear TS,

This is the 48 hours.



Will post a 72 hour tomorrow... Comments?

Oops, this 48 hr blotter spot picture doesn't show any 'shape' of centre zone indicating the oils dispersancy capability is like new.
The blotter is bright coloured and not greyish/darkish indicating there isn't much of contaminants or dirt ... pointing to an internally very clean engine.
The picture resolution doesn't show a 'whitish ring' at the outermost diameter of blotter, so couldn't say there is fuel dilution.

I would expect a 72 hr shows no differrence from this 48 hr blotter , though.

Dumping this oil at 5000 km usage appears too early in my opinion.

6,000km
Mercedes GLC250
5 months since last change

For better viewing, light then back of the sample using you hand phone light , much much cleaner view

Engine oil details?


Good idea from you,

Petronas Syntium 3000, 5w30

thrown the blotted paper away...........

Petronas 5W30 comes in Syntium 800 being a blend with SN GF5 .....

...which sounds unsuitable for your MB GLC 250.

Do you mean to say Syntium 3000 fullsyn 5W40 SN C3 MB 229.31?

For advocates of 5000 km (3000 miles) engine oil change intervals ....

72 hour blot of my Aisin 5W30, Hyundai G4GB Engine.

Current oil mileage 14,990 km.

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 .

Thank you Zeng for the comment. Quite surprised this oil hold up quite well, I actually plan to change at 16,000 km as it's been almost 7 months of usage. I've never kept oil for this long and for this many km's before.

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.

Only RON 95, mostly Petron, sometimes Caltex and BHP, very rarely Petronas, only once Shell.

Hi guys, just realised such thread. And first time posting. I know it might not be useful to get a sample at 3k but I want to practise and get it right.

Attached, Honda City 2011, odo at 100km, 3k since oil change, this is the first time I used Honda fully synthetic oil, previously always on their semi synthetic. Previously on caltex 95. Now changed to petronas 97 starting from Nov 2017 since can get petrol card from lazada on discount.

This pic taken after 60 hours sample is taken. Sample take around 5 hours after short ride to local pasar.

Any feedback or more info I can provide?

By the way, how would we detect if its fake oil? Any tell sign?

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.

This Honda fully synthetic at 3000 km has some sign of centre ring (though elongated in shape due to handling or slanting placements after drops on paper), and to monitor closely for extending OCI.

It's outermost rings indicates presence of fuel, possibly caused by sampling while cold, it could also mean petrol fuel gets into engine oil during engine operation.

There is a chance that an Euro 2 RON 97 of 50 ppm sulphur may slow down engine oil contamination from sulphur acidification.

No,blotter spot test cannot differentiate if an engine oil is fake or not. It may indicate engine oil conditions at relevant km reading, which in your case I personally am not 'impressed' with this Honda fullsyn for now, in relation to the Aisin 5W30 above.

But we need comparisons of blotter spot at higher mileage, besides comparing blotter of other engine oil types (as listed in post #1) in similar engine under similar driving conditions.

Hope it helps.
