Do you think m1 or pp would do a better job of cleaning an engine? I'm not interested in auto rx. Just an older engine with no sludging problems.

When engine? M1 5w20 has done some interesting "things" for me by way of junk showing up in the filter.

I have my own thoughts about oil cleaning engines based on my experiences cleaning and removing paint in my business. Sometimes you can get a surface just so clean, then a simple change in product gets the remaining junk off easily, where the product used before stopped cleaning. It's happened many, many times, a simple change of product gave better results.
PP and Mobil 1 probably do a fine job keeping an engine clean and doing some cleaning of their own. Routine oil changes following mfg suggestions should keep a new engine clean.
The problem comes in when someone buys a used car with an unknown history. If you don't use a product like MMO or Risoline then I think changing oil brands will do some additional cleaning. EG if you're running a steady diet of Mobil 1, and then change over to PP, or Castrol Edge, or something along those lines the change in Chemistry might clean something up that another oil left behind. I'm pretty sure on this although I have no proof. I've been a MMO user for many many years and my engines are very clean. JMO

I like to apply practices based on personal observation/experience, like that. Thanks!
Cant comment on PP but my M1 fed engines have alwasy been clean as a whistle.
I switched my 330ci from GC to M1 10w-40 High Mileage and I can't believe the difference! When I changed the valve cover 6 months ago the GC rewarded me with a perfectly clean engine. The old girl is aging so I went to a higher viscosity oil with an A3 rating and settled on the M1 HiMileage.
On BMW's the valve cover cap always seems to have some sort of soft varnish on it; easily wiped off, but none the less there, been that way since new. I used M1 0W-40 for a while and it was the same as everything else. Hey I lived with it.
After running the M1 HiMiles oil for roughly 1000 miles that oil cap looks like it came out of the box! Perfectly clean. Based on this I have decided to change out the M1 at 3k miles because I guarantee you it is removing a lot of unseen stuff - I don't want a clogged oil filter.
So the answer to your question is yes, in my experience, a different oil can clean your engine up. Keep in mind though, M1 High Mileage oils are probably highly detergentized to clean up an engine and it basically says so on their web site.
I plan on letting the M1 take this M54 engine to her grave, hopefully around 350k (as in I can't afford a new one to replace her).
Cheers!

I've had a lot of good luck with M1 HM. Most of the BITOG members agree. Then again, PP is good stuff. Using it right now as we speak. Pennzoil's deal at WM with the $15 rebate make it the best bang for your buck.
