Engine repair question about 2008 Town and Country 3.8L
You would have been correct only a few years ago as this stuff is fairly new to the market, still. I share your same sentiment regarding the older stop leak stuff you and I are most familiar with. It's pretty much snake oil, but this new generation of stuff can actually work. And of course you know it, the auction and used car guys just love it. lol One of them......I think it's the K&W product has a double your money back guarantee on it. Of course getting it may prove to be more trouble than it's worth. lol
