What works for one doesn't seem to work for others. For example, GregK24 in Florida reports that his K24 engine runs very quiet on PP 0W-20 or PU 5W-20 (I forget...maybe both). Mine runs pretty loud on both of those. But it's quiet on Mobil 1 0W-20 and 0W-30. I've used both and liked both. I'd still use either if I ran oil out to the full MM interval, but I don't, so I don't get any benefit. I'm currently using Formula Shell 5w30 and it's pretty quiet. Temperature certainly influences it, but even in the summer, I have found that a "loud" oil in my engine is a loud oil, no matter what. And a quiet oil (like Mobil 1 0W-20 for example) keeps the engine purdy quiet in the winter. I have not yet used Formula Shell in the winter. I just started buying it this spring at BJs.
Our Acura's J35 runs quiet on everything. I haven't yet found an oil that makes that engine noisy, with one slight exception. I've used M1 0W-20, M1 0W-30, PU 5W-20, PP 5W-20, PP 0W-20, PYB 5W-20, PYB 5w30, QSUD 0W-20, QSUD 5w30, and FormShell 5w30 (which is in it now). The slight exception is I could hear a slight "lifter tick" with M1 0w30 in the sump. The only reason I really noticed it, though, is because that oil was in the engine when I did the timing belt, and I was running the engine a lot in the garage purging the cooling system after the job was done. Otherwise, I couldn't hear anything. And I haven't noticed a similar noise out of other oils.
I have heard that some J35s exhibit loud piston slap when cold, but our engine is not one of those. Our K24 will...oil dependent. But our J35 is mouse-like.
