I found the Pennzoil Platinum Dexos1 Gen 2 PDS Pennzoil Platinum 0W-20 PDS they are now advertising 50% cleaner than the toughest industry standard. they previously had to lower the old formulation to 30% cleaner when the new Gen 2 deposit test came out. I think its very impressive. Not much seperating PP and PUP now that they made PP thicker and cleaner than the previous formulation.
