Will be using this oil for another 2k km. Normally I run it about 8k+ before oil change. Let's wait n see the result then. BTW, the photo was taken after about 26 hours. Will do again in another 1k km.
Thanks Zeng for your comment.

Only found this useful thread!!!

Any sifu here twach me?

Toyota Vios NCP 42, Engine: 1NZ-FE



Petronas Synthium 800. Change every 5000km.

Do I need to post 24 hours? 72 hours?

Image attached is 12 hours

You're most welcome.
Btw, is this Perodua SN or SM?

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.

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 ....
https://www.bobistheoilguy.com/forums/ubbth...al_#Post4725400

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.
