Penzoil has better reputation at cleaning , but beside that theyre both great oils! whichever is cheaper buy that.
I personlay would choose PP over mobil1.
A better "rep" or just better advertising? Remember those PP and PU claims are only for 5w30 NOT their whole line.
All I know is this. I ran M1 10w30 gold cap in one of my evos for 40k miles and when I pulled the valve cover off to install race cams this is how it looked.
Evo 9 with 40k miles

That motor was on a track almost every weekend. Granted it's not showing the block but the head looks pretty darn clean to me.
Seems M1 is the oil everyone tries to beat. Must be a reason for that.

That is clean indeed. Thanks for sharing that image.
What year was that picture taken? Wow. What kind of OCI? Beautiful engine!
This pic was taken in 2010 I used M1 10w30 (factory fill) gold cap and changed it every 3k miles due to the track use the car saw and it was also my daily driver.
After the race cam install I ran RL 5w30 for its high moly to help with the high loads the cams/valve springs would bring. Even though it was a roller rocker set up. .I felt more zddp would be needed in this case. M1 served this engine well and was factory fill in every Lancer Evolution.
That is why I use M1 0w40 in my GTI with confidence.

I know a guy that drag races a 1970 Chevelle that has a very large engine. Can't remember the cu. He runs Mobil 1 10/30 and has great results. By the way, The engine pushes close to 900 hp on the engine dino.
