I too used the cheapest Fram filters I could get for about the last
150,000 miles on my engine.  Now I get the oil light flicker after about
1500 on an oil change.  This is with the Mahle filter, and is due to a
worn engine and fuel dilution of the oil that thins it out.  The fuel
dilution comes from the poor cold running with misfiring until the
engine warms up.  I'll probably stick to the Mahle with my next engine,
who knows, maybe my old one would still be good if I had done this
originally!

Personal opinions are the rule with oil filters.  But here are two links
(both part of the same site)  that show a more thorough approach to
opinion forming, although the Mann/Mahle filters aren't tested.
