It has been a while since going in to Walmart. Forgive me if this has been mentioned before but I could not find any post about the change in Supertech oil filters. All the white cans were in the clearance section, replaced by a blue can. Only took a quick look but noticed the white ones had a metal core while the new blue are plastic core. Does anyone know who the manufacture of the new blue ones are? Are they still a decent filter to use? Here is a youtube video of one cut open. Just found a 8 page post here. Sorry for the post.
