Champion filters rule?
 

Suddenly occurred to me...I've seen a couple of oil-filter threads here in the last few weeks, Fram sucks, Fram doesn't suck, Mahle this, Mahle that, Purolater is just as good, they're all made by the same manufacturer and given different trademarks, etc....

General aviation airplane engines--air-cooled flat-four and -six Lycomings and Continentals--universally use Champion aircraft-engine oil filters. Is there a lesson here? I'll continue to use Mahles for our Porsches, since that's what they're intended to use, but if anybody wonders about aftermarket filters, I have never in 35 years of flying seen a Purolater or Fram filter on a light aircraft.

I have been using Mahle and Porsche oil filters on mine but the outfit that supplies filters for lots of industrial applications in the area sells filters by Baldwin. Anyone got an opinion? I like dealing with them as they are also an Aeroquip shop that makes my hoses.
