The mechanic skills I have aren't up to Trav's, but I first started working on engines around 1958. I'm well versed in "peculiar engine noise 101". Seriously, I hear noisy engines often, but none of them are mine.


I think that you've missed the point that I was trying to make.
I'll put it this way and then leave it alone:
Put a fill of Syntec 0w30 in either of your high mileage four cylinder engines and you'll be astounded at just how much smoother and quieter engine operation becomes.
Normal noise is hardly the same as noises signaling impending failure and even those with zero mechanical skills can usually detect the difference.
Some oils are simply better at masking normal mechanical noises than are others, but if you've only used one oil, you'd never know this.


After using Mobil 1 oils for nearly 40 years with great success, I ain't changing. LOL!

Nothin' wrong with it.
I've used plenty of Mobil 1 over the years and as I noted above I never found it to make for a noisier engine.
I do find thicker oils to make for a smoother and quieter engine, though, including the thicker grades of Mobil 1.
GC 0w30 made anything I ran it in smoother and quieter as compared to Mobil 1 or Pennzoil Platinum 5w30 or Mobil 1 0w30 but it was a much higher HTHS oil.
Thicker is typically smoother and quieter.
