I didn't follow OEM recommeded change intervals of oil filter typically about 10,000 km ..... strictly.
Basing on oil change convenience, I do replace oil filters after 16,300 km and also 15,000 km of usage matching with engine oil change activity out of convenience.

Im on mobil 1 EP too and changes filter around 7-10k mark.

I felt a slight improvement after changing the oil filter in between. But yes with mobil 1 EP there's a recommended filter for one shot 20k km use.

Changing oil filter in between oil changes is indeed another way of 'topping up' new oil with additives , thus this practice could 'prolong' OCI if one so wishes it.

Thanks.

Oil change monitor suggesting oil change already, 2 months to go according to date and 4200km to go if following mileage

What brand is this engine oil? 😂

Shell helix ultra

Hard to comment without further details like km/month in use;engine model, turbo? direct injection?; engine oil grade/specs etc.

eo looks clear, but hav to wonder how much sludge-like deposit already accumulating in the crankcase

engine oil (usually) contains detergent to prevent sludge from happening. now wat will happen if the detergent is depleted?

12000km , diesel turbo , helix ultra 10w 30

Edit : more intense light , more than 24 hours

Helix Ultra doesn't offer 10W30 in M'sia.
Assuming this is an Euro turbo engine with Diesel Particulate Filter specifying use of this oil etc ......
and further assuming this oil is Shell Helix Ultra ECT C2/C3 0W30, whose typical oil life could be upto 30,000 km in some Euro engines......
..triggering oil change at 12,000 km here, with due respect to whoever is this OEM, I'm of the opinion its oil life monitor is too conservative and I personnaly won't follow it in my car that's without warranty requirements.
This is 'confirmed' with this well done (and lighted) 24 hr blotter spot shown above.JMHO.

Zeng...... this is Aisin fully synthetic (PAO+Ester) 5w-40 API SN.

Done 12k kms. Used on Elantra 2.0 NA (G4GC). Pic shows 48hrs blot, sample taken hot.

Huuh ........ that's no joke. It's hell lot of clean and transparent, not much of dark coloured contaminants such as soot, dirt, combustion byproducts etc.
It's like my 5000 km oil blotter above.
This oil is powderful, that's for sure.
At the same time , this Hyundai engine is very clean and in tip top condition. How long mileage is this engine, btw?
Any intention of prolonging oil change of existing sump oil ?

Edit: Heck , this is 194k km engine. Two things here:
a) there is no doubt about the capability of this engine oil(Aisin fully synthetic (PAO+Ester) 5w-40 API SN), and
b) this Hyundai engine is hell lot of a clean at 194K km indicating high quality of this engine design and manufacturing , maybe helped by your driving habit and maintenance regime.
Japanese OEMs better buck up, IMHO.

Edit 1:only very faint shape of centre zone, and is fully transparent not opaque.
Edit 2:Sorry, I think this 12,000 km Aisin 5W40 oil blotter is obviously better than my 5000 km Total Quartz 7000 Energy 10W40 A3B4 oil blotter.

Thanks for the comment, zeng.

Actually this engine is minutely burning oil. I suspect it is due to worn valve stem seals as there is zero oil stains anywhere.

Had to change out the sampled oil right after I did the blot test, as oil level has reached uncomfortably low (for me) and no point to top up. Changed with another 3.5litre of Aisin PAO+Ester.

Previously was on 2x Totachi FS Touring 5W-40 which was on sale in Lazada. Also ran through Kendal GT1 LT 5W-30, M1 0W-40 and Shell Ultra 5W-40. Basically whichever oil I can get on discount (circa RM130-160 range), without breaking the bank.

I bought this car pre-loved, so I have no idea how it fared on previous ownership. Once I got it, in went the SHU and M1 for cleaning. I can only track from its 79k-th km onwards, till now 194k. OCI would vary between 10-14k km and ori Hyundai (Mann manufactured) oil filter.

Aisin FS 5W30 (non-PAO)
Hyundai Elantra 1.8 G4GB
Picture taken 20 hrs after.
Current mileage 13,536 km.

This 10 hr blotter spot doesn't show up any 'shape' of a centre zone and that is a good indication of serviceable oil, though at 48-72 hr a centre zone may be observable clearly or faintly, IDK.

I would speculate this oil [Aisin FS 5W30 (non-PAO)] is of high quality though it's said to be non-PAO and is still serviceable for another several thousand km say, up to 16,000-18,000 km.

You may take another blotter spot after 1500-2000 km if you are extending its oil change.

Oil consumption due to hardened valve stem seals can be assessed on early morning start first thing in the morning by looking up for bluish exhaust smoke upon start-up.
Alternatively oil consumption may be caused by worn piston ring sets by looking up for coloured smoke upon engine deceleration/acceleration at medium speed cruising.

Not sure about Totachi and Kendall, the M1 0W40 and Shell Ultra 5W40 are top tier oils even suitable for most European Continental engines.

Not sure why a lowish 200,000 km engine has oil consumption issue whilst its combustion system looks top form.

No smoke at all from the exhaust and no leaks but yet 90% of the engine oil dissapears within 2.5k KM. Not mixed with coolant nor any check engine lights..

What maybe the issue?

What's your engine model and whether there is a cooler installed in the engine compartment ?

Peugeot 308 THP156 engine, not sure about coolers..
