Used your product in my '04 VW Passat 1.8t after replacement of oil pump and screen cleaning.VW recommends an engine flush using Wynns products as per their tsb. Was sceptical, but after dismembering the oil filter at the 1k recommended replacement found nearly the entire filtering media covered with hard sand like deposits. At 2k dissasembled the second filter, and while results were not as dramatic as the 1st, I agree the 1st stage can go to the 3k limit. Have to say I was amazed at the amount of coke your product dissolved with no apparent harm. Was a cold winter this way and used Motorcraft 5W20 semisynthetic with top off at 1k and 2k of shell 5W30. Very satisfied. Used the second bottle on my 270k Ranger and my 200k Merc Grand Marquis. Will be reordering shortly. Thanks Dan
