Time for some people to sit down and start telling unsubstantiated stories about Wix oil filters. Sit down and unfold a nice long tale about how the Wix can't flow, lose power with it, or suddenly there is ticking with the Wix, but when go back to the XYZ, all is quiet and power comes back. Repeat a few times, pretty soon people are saying it's true because somebody else said it's true, even though it is false. OMG if ticking is heard, it must be the Wix. It is very easy to do this on the internet. That's how I see it, that's how I tell it. Got to have proof of things.
