I've learned a lot of this forum in the past weeks so I could not resist cutting open my first filter, a Motormaster Formula 1 from Canadian Tire. It costs about $2-3 more than the Fram and QS filters they sell. On my examination (this may not be a surprise to many of you experienced guys) I found a Fram filter complete with cardboard endcaps and neo bybass valve. The only difference is the orange gasket which is supposed to be PTFE treated for easy removal. I've been buying these filters for a while thinking they were better and hope that after this post, no one else will.
