Yep, I agree that M1 is loud compared to others. Why are some insisting on scientific proof? If you hear it, that's your proof. People on this forum know how their engines sound. They can tell when it quiets down or gets louder. The quietest oils for me are valvoline synpower, magnatec, and pyb. All 20 wts. Vehicles are 2011 elantra and 2013 civic ex.

Conventional mineral mineral based oils have a better P-V coefficient, which is why some experience a quieter engine.

I haven't heard too much noise from a Toyota V6 or V8 on PP, Magnatec or Chevron. I have my parent's LS430 on Idemitsu Zepro and it seems to sound like a Lexus should but a little more silkier due to the higher Mo content of Idemitsu's oil. There was Warren in the sump before and I didn't hear a discernible difference. It seems like Chevron(Oronite), SOPUS(Infinieum) and Idemitsu are big fans of moly, while Castrol and P66 are believers in Ti(but it's not to be found in the GTX family or the cheaper lines of P66, just Kendall and P66 with Liquid Titanium).

Some engines are just noisy. Small Toyota I4s, German V6s and a few others will be noisy no matter what you use.

I believe that is true ^^^^^

It is engine dependent... My lady's Camry was loud as all get out on Super S and Cam2 mix... Yet my Nissan Altima VQ was dead quiet on Super S...

Same. Used M1 in my corvette, smooth as butter. Used M1 in my subaru, sounded like the engine had nuts and bolts in it.

Sound is tricky stuff - when I was dB meter testing and the PUP was the loudest - it sounded loud under the metal roof in front of my shop.

Short time later I went through a drive thru for bbq - and against the brick it was not loud
