The limit is up, its 9 months today the oil, albeit 3,444KM only.
My limit is 6 - 9 months oil life or 5,000KM, whichever comes first.
Let's see how NOT stress the engine oil is............

Engine oil is a very cheap insurance.
More so in USA where Mobil 1 0W-40 SP version is so cheap , any good high performance oil is CHEAP in USA, and genuine MB engine oil filter is so cheap too. I am using DIY for labor as reference.
To an extend yes the oil solenoid un-plug does help ,but since I have always limit to 5,000KM /200 Hours only for my engine oil,
the oil filter element been yelllow-golden-ish color and never dark or black.... since the day I own this car.

@S-Prihadi do you send your oil samples to a laboratory for analysis? In the US one of the main service providers is Blackstone.
I never bothered to test the oil if for my car, its US$159 to do so back in 2018, and the data parameters is nothing as complete as USA BlackStone.
Below is for my client marine engine.

See how lame are the test parameters ?
So it will be useless for me, can't even track contamination like anti-freeze.
You guys in the US are lucky dudes when it comes to Oil Lab facilities and price point.
For me to get the parameters to be as complete as BlackStone, maybe US$400 up would be the cost, assuming they have such test capability.
Now the glitter control for the engine oil filter.
I kept it on purpose for 32 days. In a closed bucket to prevent dirt from contaminating it. Let the oil drain away.
.
I should have used cutter instead like the 2nd try and not a steel saw to cut the filter paper element away like 1st try. The plastic shredding is a lot
1st try
2nd try using cutter, better result. Clean.
Stretch the dirty side as long as I can pull it.
Inspect slowly with double magnifying glass and torchlight.
Only about 5 or so glitters...... so very small. Difficult to take photo, if angle is wrong it won't reflect.

Here are the results of my last two oil analyses. The right column is the oil that was in the car when I got it. Coincidentally, right after I got the car, the 10k mile service interval notice came up, so I changed the oil at 10k mi. It was of an unknown age and type.
On the left is my next oil change which happened at 6k mi. In the center is what Blackstone gives as the normal range for LiquiMoly 5-40 with this mileage (based on... something...):
I will change my oil next time around 4-5k mi, but I think it is interesting to notice that you can see almost no difference between my 6k mi oil, the 10k mi unknown oil, and the "values should be" column, based on this data.
We'll see if we can get to the higher end of the normal viscosity range with the next change with a shorter interval. The OPR solenoid has also been unplugged for a few months though, so there will be some confounding variables. If the next change after the upcoming one is at 3k, with the OPR solenoid unplugged the whole time, that will give a "best case".
Edit: also worth noting is that the viscosity difference from 6kmi to 10kmi is very small, so if the 10kmi oil started off at the upper range of normal (around 15.3cSt), it did most of the drop in a period less than 6k mi.

... I've seen that lower viscosity oil shears rapidly between 1500Mi to 2000Mi as it's been overheated. This is caused by viscosity polymers getting wasyed to reveal the stock oil viscosity.

MS! that's an interesting collection gathered by your filter.
It looks shinny like aluminum not oxidized like steel would be.
Have you seen the amount of magnetic sludge stuck to your Cam Sensors??? nicely alligned by magnetic field (x4 sensors!)
Do you think neodymium magnets attached over the plastic oil filter enclosure can help a bit???
The last time I took out my cam-pos sensor it was clean from any magnetic sludge which we can see on tranny oil pan magnet.
----------
The magnetic oil filter housing add on magnets I have installed on my friend's 2024 3.5L Diesel, Toyota Land Cruiser 300.
But the engine does use steel canister throw away engine oil filter type, unlike ours. So the magnet can stick on its own to filter canister steel body.
I would think such strong magnet may help to capture to a point with ferrous metal.
The engine oil filter position is forward facing, like main pulley.
.
He also bought a flat shape 2 inch x 2 inch flat magnet for tranny oil pan.
It is so strong damn. It is placed on the outside of the tranny oil pan.
So far okey, the magnetic field did not interfere with any sensors on the tranny internals.
I think this tranny oil pan magnet TM360 we can try too on our tranny.
Crazy strong magnet, do not get your hand get pinched !!

I keep my oil max 3,000 miles or 5,000KM or 9 months.
Very likely my engine enjoys majority of the engine oil time, while still being a "very much in-spec" oil.

When I send in my next ~4kmi oil sample, I will also send in a sample of fresh LiquiMoly to see what the starting point is! Then we can start to bracket this behavior.
I can also grab a 1500mi sample without doing an oil change and send that in. That will probably be in May or so.

I think Blackstone saw me post this because within a couple minutes of posting, they sent me an email about price increases.
I didn't get my 4k mile oil analysis report back yet, but I got the virgin LiquiMoly 5-40 report back.
There is some reduction in viscosity after 6k miles, but the LiquiMoly 5-40 starts off at the low range of the "should be" values and therefore ends up outside the limits of what "should be".
It will be interesting to see what the case is at 4k miles.

That is good info to have for comparison sake, thank you for sharing.
