I don't remember anything negative here about WIX. On the other hand, I have seen very little suggesting the extra expense over say a Purolator Premium Plus makes a bit of difference. Much of the extra expense is due to selling through jobbers with low volume and high markups. If you feel a high price automatically means it works better, buy them. If you want proof, look elsewhere. Yeah, they are better than Fram, and maybe the new Champions, but there are other brands that may be just as good.
