What do you conclude about a "loud" oil?

There we have it folks …
I think the big question is whether or not making more noise equates to more wear, but that in itself is something not really anyone could verify without a strictly controlled test. Sometimes a louder engine is healthier than a quieter one. Take adjusting the valves for example. My noisy 22RE Yota 4 banger makes a lot of valve noise, yet is running better now at 320,000 miles than it did 150,000 miles ago. If I tightened up the valves to quiet them up as much as possible, I could very well burn them out in short order.
Interesting topic that is probably too abstract for anyone to know if loud oil is worse for wear than quiet oil.

"Taco tick". Normal. If it's not ticking....something probably wrong with it!
Mine has 80k on it. My coworker's has 340k on it. They sound exactly the same at idle.
Never heard of a such thing. Oil is oil. Unless I don’t care enough to listen
My 2005 Tacoma 4.0L V6 is pretty quiet IMO, even compared to other vehicles I've owned over the years.
You must have ears that can put a hound dog to shame
Oh I wouldn't consider the ticking loud at all. But it's the nature of all the GR engines.
Yep, that's what you get with the DOHC and shim in bucket valve design - no hydraulics to keep valve shim clearance to zero.
I been thinking about this as well.. the oil I just switched to seems.. like it amplifies engine noise.
Those in the know say there is no scientific basis for this.
I still think some oils seem to cushion more... But since this can't be "proven," it is the subject of entertainment.
I could talk more about why I think this but I'll leave it alone.

Ran a fill of Valvoline Synpower Maxlife 5w20 in my 2013 2.7L Tacoma. Aka the test mule.
It currently has a fill of Rotella Gas Truck 5w20 and it is noticeably “louder”. But I bought 6 -5qt jugs for my stash at less than 8$ each.
Wish I had sent off the maxlife for a uoa. Both maxlife and Napa syn run like silk in that engine.

FWIW, the 1GR-FE in 2010 and newer FJ Cruisers, 4Runners, and Tundras, has almost nothing in common with the 1GR-FE in the Tacoma, or earlier FJ Cruisers, 4Runners, and Tundras, besides both being 4 Liter V6's.
It's so different, I can't understand why Toyota didn't change the engine model designation beyond stating Single VVT-i vs Dual VVT-i.
The Dual VVT-i version has roller rocker arms and hydraulic valve lash adjusters, amongst it's many changes.
Yep, despite my nearly lifetime as a Motorcyclist, listening to music, and working on insanely loud racing vehicles, I still have decent hearing according to the Audiologist I recently saw. I learned to use earplugs early on, and always have a pair with me.
I can also hear the difference in engine operating noise, with different brands of oils.
They still share the same 60° block, stroke, bore and, as far as I know, most of the lower internals
It's a 60° block, but not the same as the single VVT-i version. Different crankshaft, pistons, cylinder heads, intake, exhaust manifolds, etc.
