Isn't the bottle green? Ducks are green. So Quacker State makes sense!

I ran 5W-30 in the truck and 10W-30 a few times and always ran 10W-30 in the GP. I finally had enough of the noise and switched to Chevron Supreme and both engines were very quiet.
I have never tried Mobil 1 since and I still hear many people saying the same thing these days so I have no desire to try it again.
Same here,it was noticeably louder on all our cars I tried it on too,with the exception of 15W50,which was smooth as glass,as I'm guessing because if its high viscosity.

Will there ever be somebody with a technical reason for loud oil ?
... or will this end after 9 pages of unsupported words like always?

I'm thinking it's a viscosity issue and the small differences in the 100 C viscosity of each oil. Want to prove it to yourself? Next oil change, leave out 12 oz. Drive the car to bring it up to operating temp. Shut the engine off. Pour in a can of STP oil treatment. Take it for another drive. If there is no change, I'm mistaken.
It's also possible some oils have a different coefficient of friction and it always puzzled me why that is not reported because it is such an easy thing to measure.

I guess they don't dare to do that. You are the only one to do that AFAIK.

I am surprised you have a LS430 that does not run extremely smooth and quiet. That is one of the best engineered and smoothest engines ever produced and I know because I own a 2006 GS430 and a LS430... I use 5W30 Valvoline full syn with Maxlife and it has been running fantastic like a new car. Maybe you are having an oil filter issue or mechanical problem...

Turned out that way on my ecoboost … the PUP and M1 5w30's were noiser than the 40's …
I did not expect M1 0w40 to be even lower than M1 5w40 … but it was …
What's troubling to me is all the claims regarding a brand … when the specifications are very similar to other makes …
Further to make so many general comments regarding a company that uses many combinations of base stock seems unsupported IMO …
That ecoboost was a noisy engine … my 5.3's are quieter on 0w20 … so the Ford was likely OHV and chain noise …
I did not expect M1 0w40 to be even lower than M1 5w40 … but it was …

Well I did dB testing on a Ford and GM engine and the PUP was noiser than M1 in 5w30 … but in fairness I did not try a PP 40 in the Ford … the GM was both 5w30 and PUP was a bit louder …
Well, both are great oils and my test was not truely scientific … just made better with a dB meter in the same place and engines were fully warmed … and I did stick with the same oil filters …
I quit PUP over availability/price … and now having so many 0w20 engines … just use M1 EP …
(PP is in the Cruze now) …

Am i the only one that pours the oil in and doesn't try to [censored] the change in sound from the engine?? Why spend any time thinking about this at all? Has it really even been proven that "louder" oils have any negative effect? There is no science to this at all.

Like many allude to, less noise=less friction.
With all the info, data, analysis, ingredients, arguments, etc, and trying to decipher through all the info and opinions, myself, personally, I think the ear/hearing test is one that is written off far more than it should be.
People post ingredients of this oil and that oil and state this one is superior to the next one but when UOAs roll in they show the oil really isn't that special at all.
Same as VOAs, they look good on paper but when you dig deeper and realize some ingredients counteract others, or can, and some info is proprietary, sometimes just listening to your engine and reading UOAs is more informative than any of those things, imo.
Like what has been stated here in this thread, many find Mobil noisier than others and when they see UOAs that have above average wear metals in them, they switch oil brands and hear a much quieter engine and see much better looking UOAs on average.
I know I will be flamed for this, but this is the reason I now run Pennzoil oils, plus, on average they are cheaper to purchase as well. (Don't forget to compare jug sizes/amounts)
I use to be a Mobil fanboi too until I joined this site and seen and learned a thing or 2.

And yet I've made it all these years and miles using M1 nearly exclusively in my engines. How is that possible?
I myself have never had an issue with any Mobil1 product. My wife's current ride, a 2012 Highlander with the 3.5 V-6, has quietly survived nearly 120,000 miles on Mobil1 and 10k OCI's.

And probably having those engines run louder than they could've been.
