Overkill, with all due respect, if you have only used Mobil-1 for decades, then how can you suggest no other oils run quieter? Here are some things I have noticed over the years and, imo, they simply can't be written off as bunk. Switching my 4 stroke Yamaha Vector snowmobile from Yamalube to Mobil-1, I noticed a significant difference in the noise coming from the engine. Switching my truck's oil years ago from Mobil-1 to Pennzoil, I also noticed a noticeable difference on how quiet and smooth it ran. This past summer, changing the oil in my son's car to Pennzoil Ultra from Pennzoil Platinum, both of us immediately noticed a difference on how quiet it was. I know many will say, well, you are removing the old and adding new, and although that does have some merit, doing oil changes and being around engines for the past 40+ years, one begins to learn/get use to how things sound after doing oil changes.

There is a strong thread of mythology that runs through the various claims made regarding this oil or that. Separating the anecdotes and legend from fact is daunting and there is precious little of the latter comparatively. While the claim that Aunt Margaret's 1997 Accord was loud and down on power on *insert oil here* may get stashed in the memory banks of those already operating in a partial echo chamber and trotted out at a later date as "proof", it isn't. No matter how many times they repeat it.
