Yes, of course, all human observations are inherently subjective. The notion that a human is not capable of discerning a change in volume or sound pitch, though, is dubious to me.
I understand people can be mistaken. I don’t think they always are on this particular topic.
No doubt that the human ear can discern differences in sound. The issue here is the sampling method along with too many variables. You can't compare used oil to new so it's new to new or old to old. Either way for most people there are months in between those 2 moments in time. Can you really tell me you can remember exactly how loud something was 3 months ago? Not to mention variables of environmental conditions, surroundings, even condition of the vehicle itself.

I believe my experience was accurately observed. The change was immediate and substantial in my particular application, and corroborated by my wife’s independent observation.
You may not believe it, and that’s fine.
Exactly what I’ve always thought. Some people must have a hecka acoustical memory.
I’ve had musician friends able to tune instruments by ear. I certainly can’t do that. But I do drive my vehicle 30k miles per year and know every squeak, rattle, vibration, etc. I can instantly tell when something is different. On the other hand people drive around with brakes metal to metal and don’t know.

Yeah - it’s going to double in size since the OP left the building right away …
For noise comparison, I use a cell phone DB app.
I like to finger my oil warm.
Could find this of interest . Scroll down for a look .

if his voice was less annoying yall would love him or if he had a drawing and other info of the specific cleaning molecule they use (Random educated guess: Look towards the ZDDP chain…)

that arco graphite oil was nothing special and you could never tell when it was dirty. it stayed in my car for only one change
the ticking is probably injectors.
Finger test........hmmmmm

Mobil1and Valvoline (0W20) made my K24Z2 engine run noisier as well. I switched to Pennzoil Ultra Platinum and the noise went away. I am super happy with the way it works with this oil.
Lots of bucket tappet engine experience here, for better or worse. They can definitely make noise if the clearance is close to limits or is out. Shim adjustment are obviously never perfect clearance, always just an acceptable range. Viscosity and other factors can definitely change volume and perceived noise level, even when clearance is technically correct and in range. BTW, we routinely called them lifters in the shops I worked in. Not agreeing with OP, just that some of the comments in the dog pile are incorrect in my view.

It's a ridiculous notion that how different oils sound, look as far as color, smell, taste, or feel between the fingers have any meaningful value.
I can tell the clearance in my worn out swaybar links is larger than it was 6 months ago. I also think the rear is wearing quicker than the front. I sit in this car 15 hours or more a week. Of course I can tell something has changed, and a real time A-B comparison is not needed.
Musicians can make comparisons about the tone of instruments they are familiar with, with years in between, with high accuracy. And tuning accurately by ear is completely commonplace from what I have seen. ( musicians in family, friends, etc.)
I was an average mechanic, nothing special, but what I learned was from much more experienced and talented guys:
Is the shops I worked in years ago,
Everyone would use a manometer to synch carbs, but final fine adjustment was done by ear. This was commonly done, nothing special.
Final idle mixture was also done by ear.
The six senses are very valuable in any mechanics, in my view.
It’s not accurate to demean this, or the experience of those who recount their experience.
And further,
Those who do, only betray their own ignorance and lack of experience in my view.

Agree. I have seen this myself.
And any conclusions you have can also be ( almost always are) subjective with data.
Hopefully people here are aware of this.

Can you guys tell the difference between a steinway and yamaha grand piano? Because professional and amateur pianists can, all without using scientific testing.
Subtle differences in sound are easily perceptible to those who know what they are listening for.
