I was at OR last night - MGL/MSLs are made in China or Vietnam. They seem to be Premium Guard products.what's funny (ironic) is that the micogard select and regular oil filters are made by the same company that bought out WIX! mann/hummel.. So why is it that the "junk" we're seeing take over Wix isn't taking over Oreilly's house brand?! odd..
