Hi chemistry,
This 48 hr blotter spot has a very large centre zone , but without a clear ,dark-coloured perimeter ring around the centre zone (which is a good news) indicating a very potent or strong dispersancy (and detergency) capability typical of a modern HDEO diesel oil.
Btw, this PC Duron SHP 15W40 is a semi-synthetic HDEO with ultra high specifications in CK4,E9, ECF-3, other than dual rated SN.
The rather grey colour of the centre zone indicates quite an amount of combustion by-products and contaminants etc in this 11,145 km used oil sample from a carburrettor old tech engine.
The intermediate diffusion zone is good and clear.
However, I find it interesting for being unable to 'see' the outermost transparent zone surrounding the jagged edges, indicating near zero fuel dilution despite your claim of 90% stop & go traffic condition.
It appears to me this engine is very well maintained.
This used oil sample appears to be serviceable for probably another 1500-3000 km , IMHO or speculation.

Bro zeng, taken after short ride 15 mins from pasar, 4k km, 4 months oil. Pic taken after 24 hours.

Any comments is welcomed.

Going to switch to aisin as per recommended but I have another bottle of this in stock. Will finish it up and continue take sample for the other bros reference

Still using Honda fully syn 0w30 engine oil.
This pic taken 60 hours after sample taken.

Last oil change did with throttle cleaning in workshop

Hmm...... the centre zone perimeter ring appears very obvious, doesn't look good for its detergency/dispersancy.
I thought Honda 0W30 could do much better than that.
It could be due to cold temperature when doing sampling.
Next tests try do it hot, after say 20 minutes of 20 km run.
Check with previous posts from this thread, there was one Aisin oil type very impressive blotter spot test. Try use that particular one if you are going for Aisin.

cant remember if i take this cold or hot.
was thinking to switch, but till now unsure, if to go for aisin or shell. next change should be around jan.
