It's nice going from the $5 a quart VR1 to $15 for 5 Quarts of QS DEFY 10W30. Not only do I get the zinc I want with the DEFY I also get the seal conditioners. For my Ranger and Explorer I've changed from Valvoline to Pennzoil HM 5W30 because of the high moly content, I feel The higher moly and a bit lower zinc in the PHM is better for the newer vehicles with catalytic converters. I just did the oil changes tonight so I don't know how they will do yet. I do have high hopes for quieter engines. I have to say I never though I would put Pennzoil in any of my cars because I always been told it will gunk up the engine. Maybe it was just a mistake Pennzoil made with a past additive. Today looking at what's in the different oils PHM and OS DEFY look a lot better than Valvoline. Sorry to get a little off the subject. I will update when I get some miles on my new oil.
You do know that Pennzoil and Quaker State are the same company right? Both products of SOPUS.
