Way back in 2006 I had an F150 with the 5.4. The cab was crazy quiet. I couldn't hear the engine and could barely hear the exhaust inside.
It was clear as day that at 3,000 miles on Mobil 1 synthetic that I could start to hear this noise, almost like white noise static, coming from the heads. I tried various oils over the 60,000 miles I owned it since new, including Redline and Valvoline Syn, the old SynPower. Of all the oils, only Redline and SynPower would go to 5,000 with no discernible noise from the engine. Due to Redline not being API certified, I chose SynPower.
I now have a 2022 Toyota GR86. I drained the factory fill at 2,000 miles just the other day and put in Valvoline EP 0w-20. There's absolutely no question it sounds better. In fact, there was a strange noise at idle that sound almost like a cartoon phaser gun or something. That noise is gone. When cold, the heads have a slight knock sound which dealer says is totally normal, and it's better, too.
I don't know why some people say you can't hear differences in engine sounds with different oils. To me it's obvious and I feel like people who say I cannot hear a difference are morons.
