Engine noise any indication of oil quality?

Since thou art a lazy one, I will oblige the trolls just this once.
A simple search through BITOG yields a lot of similar takes.
My car ran well on Valvoline Advanced 5W20 when I was breaking it in - other than fuel dilution problems.
Any reason YOU went with 10w30? is your 2.0 Direct injection ?
Yeah, a YouTube video. Somehow I am less than impressed.
Is this what you used as your basis to say "Just what I have seen from engine tear downs"?
Everybody carries a sound meter around with them these days (also known as a smart phone) but nobody posts any data. I've always found that interesting.
I did a cat-back exhaust system on my daughter's 2014 2L turbo. Night and day improvement in both power and fuel economy.
No more gasoline smelling engine oil, and no consumption with XW40s.
She sold it and now drives a 2022 3.6L Acadia.
Her mother in law turned in a 2021 Jeep lease, and bought a 2023 1.5L turbo GMC Terrain.
Making accurate and representative sound pressure measurements is extremely complex.
Yes, my car, also, has a bit more power at Night. But it may be those three Johnny Walkers talking.
j/k
Which xw40 grade? M1 FS? Maybe a factory resonator collapsed?
I don't think my NA motor would tolerate much over 3.5cP HTHS
"Sound pressure measurements"? Solution?
Don't eat brown beans the day before a job interview or important meeting.

How do you figure?
My 2017 accord did that with PP euro L 5w30, when at a stop light it would seem noisier than normal, I just kept driving it until my regular scheduled oil change
I use a calculator since I'm lazy to pull the old slide rule out
My Ford was designed for a xw20 grade ILSAC lube which is well under 3.0 cp
And high HTHS likely wouldn't provide any "needed" greater margin of safe operation than a Resource Conserving xw30 grade
rather it would just add a lot of windage and shear losses and slow her down. She's certainly not my old '67 396 SS.
I was running the 10W30 to combat fuel dilution. Car didn't like it this year; I can't reconcile this inconsistency.
Watch - I''l find a rat's nest in the airbox and all up in the MAF, LOL
It helps to understand the physics of sounds.
Only three? What was LCol Slade drinking in "The Scent of a Woman" before the test drive?
The Escape was a west coast car and could get away with 15w40 year round. Ususally PC Duron, but any CK-4/SN will do.
Think Sea to Sky highway between Whistler and Vancouver.
My daughter phoned me in a panic because her 3500 wouldn't fit in the underground parking at the Vancouver hospitals,
Lions Gate, St Pauls and VGH. She had to pay 'n park and walk 2 blocks in a big city full of stoned zombie nut cases.
My co-worker at the railway just bought his wife a 2019 1500 GMC Elevation and sold me her Escape with 71,000 kms cheap.
Me too. Also watch the RP series on youtube posted by Tenza Motorsports. It clearly shows the cleaning abilities of RP oil.

Those pics that constitute the preview are grossly misleading, here are some snaps from the actual video:
Yes, there's some lightening on the intake camshaft bearing caps, but the difference is nothing like the video's preview.
Also, important to note that he's using their XPR racing oil, which says nothing about suitable for street use on their website:
Royal Purple said:
The XPR 5W-40 appears to be 10-22% PAO:
With a mix of other lower group bases.
It's possible that this product line has some AN's or esters in it that could do some cleaning, however that does not mean that the other product lines do. Mobil 1 0W-40 is advertised as being able to clean, but that doesn't mean other Mobil grades do.

I tested Red Line 0W-20 (HTHS 2.9), HPL PCMO Premium Plus 0W-20 (HTHS 2.7), HPL NO-VII 5w30 (HTHS 3.5), and Mobil 1 EP 5w30 (HTHS ~3.1) in two Pentastar V6 engines. I have not observed any discernable difference in how these engines operate, sound, or fuel economy.I use a calculator since I'm lazy to pull the old slide rule out
My Ford was designed for a xw20 grade ILSAC lube which is well under 3.0 cp

So how do you figure that your Ford EcoBoost engine was built specifically for 0/5W-20?
Do you understand the difference between oil viscosity and HTHS? For example, HPL NO-VII 5w30 has a HTHS of 3.5, yet it's slightly less viscous than many resource conserving oils.

Would this be along the lines of Overkill running M1 EP (I believe) and then running hpl and it cleaning out all the gunk M1 didn’t clean?
Tenza Motorsports has a series of videos about RP. He started out using the API version of RP and then he took the valve cover off after 500 miles on RP and was surprised to see how much it cleaned in only 500 miles. He then started using the HPS line and eventually worked up to their XPR line. Right now I am using RP 0w20 XPR in my 2021 Lexus ES300h. The only XPR oil you cant use in a street car is their 0w8 oil because I believe it doesnt have a lot of cleaning agents.
