You know what really cheeses me off. I go to Canadian Tire and they have what looks like 4 different brands of Oil filter. Upon closer inspection: They are all made by the same company (whoever makes fram). The DoubleGuard has Teflon in it and we all that shouldn't be in an engine.
Wix manufactured filters are what we get from Ford (thanks Chris) and most auto suppliers have them.
The one oil filter review I've read puts the Fram stuff at the bottom. Wix about the middle, and the purolater at the top.
Here's the link, though I'm sure most of you have it:
