Everyone seems to say that PP or PU is quieter. Maybe its all psychological with folks? I serious doubt there is any way M1 being "louder" in your car. Are you using the same weight and viscosity?
I have used PU in my GTI and M1 and have noticed no difference at all. I can say from my gas logs that since I have used 5w30 PU Euro L in my GTI my overall average of MPG's has dropped 1-2 MPG's. Based over a 6 month period compared to same season and what not. Happened both times I have tried PU. Once with the 5w40 and again with the 5w30 Euro, vs the M1 0w40.
So how do you like them apples?
Whats even better for me?? I can buy the M1 Euro ANYWHERE where as the PP or PU for my car is dang near impossible to find and if I do find it its cost way more money. I just picked up a 5qt jug of M1 Euro for $22.66 at Wallyworld. Cant beat that either haha.
Glad the PP seems to be the ticket for you. Just dont associate "quieter" with less wear or better MPG's. Some people actually believe this to be true.
Whew! I just changed my vehicles to Pennsoil PP. Now I can finally take my ear plugs out when I drive them! All the neighbors within 3 blocks will be happy too. No more waking them up in the morning!!!

NEVER EVER have I experienced this between any of our 6 Hondas and 5 Toyotas, unless this happens on other vehicles, no idea what your talking about...
Motorcraft 5W-20 is quieter in my DD than Mobil 1. PP is quieter in the ex's car than MC. I can't rationalize why it should be this way, but there it is.
I just switched to PP yesterday. Couldn't pass up on the $20 of gas deal. So far seems fine. I'm going to run it for about 5k miles, then replace it with more PP. I'll run the second fill for about 6.5k-8.5k miles and then do a UOA on it.
If the jug cap has a code you can enter it at the site through the end of the year I believe. If the jug cap has no code, you can no longer request a code. Always check that the jug has that sticker regarding FRN and verify an intact cap seal.

I'm at 135 and still climbing. Only buying now prior to filling the tank on the vehicles though, would rather buy oil than gasoline
If I buy jugs with intact Ps do I still get to enter the FRN codes?? I stoopped buying on 31st of June.

Of course its going to be quieter regardless of brand.
