Mobil 1 HM does a excellent job. I have not tried PU or RL.


Did you have any evidence to base that observation on? I have been scouring the net for years for evidence that oil can clean anything on its own but I can't seem to find any.

Boron is the main cleansing additive/detergent that's been known by everyone to cleanse your engine.

Difference Pennzoil versus QSUD side-by-side is the high boron in Pennzoil.

Castrol has only half the boron compared to Pennzoil.
