I just noticed on Pennzoils web site that they claim their YB Pennzoil will clean up to 15% of existing deposits. Now that's a first. I've never heard an oil company advertise their conventional oil has "clean up" capabilities until now.
Anyone else notice that.?
If you go to Pennzoil.com, look down the left side of the page.
