I ran across this interesting Oil Filter Study on 20 filters.
Many of the filters are made by the same company.
Ford only approves filters with a by-pass valve at the TOP of the filter, NOT at the bottom. By-pass valve at the bottom allows dirt at the bottom of the filter to go into the engine.
FRAM filter, or other name brands made by FRAM are the worst filters to use. (i.e. Penzoil filters are made by Fram)
Got your attention???? Here are the URLs, for your own interpretation --
