Switching to M1 0w40 causing more chain noise

There were some BITOG threads a while back about Mobil 1 oill having a trend of significantly higher iron wear than other oils across the UOA's. I know UOA's are not for that purpose, but still, it's nice to use an oil that you have no doubts about.

Don’t forget “it causes more wear too because UOAs show more Fe when Mobil 1 is used!”
Edit: I see Bill7 got the reference in before this

try using another oil..if your OCI is short/normal then any good oil with approval will do the work..why stick to one oil?
Awe man, you mean the M1 0w40 in brothers Saab 9-7 is bad!?!?
He’s been using that for a long time. Even the built 6.0 in his 71’ C-10 doesn’t care about oil.

I’m more of a results-driven fanboy; I don’t really care who makes it as long as it’s top-shelf stuff. I have favorites, sure, but I give respect where it’s due.Come on now Chris; we know you are a PUP fan boy
PUP 0&5w20 did stellar in my Fusion for well over 100k;
M1 Euro/FS 0w40 is a top-shelf oil regardless of where it’s used;
HPL has proven its worth in longevity, cleanliness & cleaning power, and protection in every thread you can find.
I’m a fan of all excellent oils, even if I play favorites!
Probably the Castrol was a group 3 oil and the Mobil 1 has a high PAO content.There are lots of posts mentioning the same condition.Think of it as a good thing,you have a better oil onboard.
I used Mobil 1 Euro 0-40 exclusively for years in a Porsche. Switched to Castrol Euro 0-40 and it became noticeably quieter. This car has 3 timing chains. Mechanic put in Liqui Moly and it became quieter still. Just my experience in one car.
You know sometimes the car owners experience (placebo sometimes) that their car gets quieter with any kind of NEW oil.
Same as with new tyres vs old.

I’ve noticed this too with M1 0W40 vs PPE 5w40. Hell, I’ve even noticed it with non euro spec M1 vs PP. There is a tincy bit more of an engine noise, can I explain it through a scientific lens? No. But I can tell you one thing, I’m not deaf or hard of hearing. You can argue with me saying YOU don’t hear it when you make the swap, well that’s your car and your environment. To each their own.
I don’t think it causes any damage, it’s been discussed here many times over, it’s still a great product at the price point.
