One's reputation and their opinion are two different things. That the shop is refutable is irrefutable. That 0W-30 is a means to a fix is debatable.

I don't love the idea of a 0W-30 "cleaning batch" either.

yeah, i stopped reading after "with 0W-30 synthetic and drove it" and didn't see the whole 1k-2k then switch back. so i withdraw my comment.

i don't know how an oil change could produce the noise, but who knows. if it's gone then "something" fixed it.

as an aside, i had a noise that i could not figure out for a while, thought it was a heat shield but turned out to be a loose alternator. the shop i use (which i consider reputable) was all ready to cut off the heat shields. i found out it was the alternator on my own...

Don't let anyone talk you into cutting shields. They are there for a reason...your CV boots will thank you.
