Hey dslofti - while our PYB can clean up the sludge left behind by lesser motor oils, it’s really our Pennzoil Platinum line of synthetics that tout our cleaning capabilities. Using the ILSAC GF-5, Sequence IIIG piston deposit test, Pennzoil Platinumwas proven to keep pistons up to 40% cleaner than the toughest industry standard. Have you considered switching to a synthetic over a conventional? – The Pennzoil Team
