Ever notice real mechanics don't use "commercial" oil filters? Go to a serious mechanic's shop, I'm not talking a quickie oil changer, Firestone store, or Sears, and look at the oil filters they are using. 90% of the time you'll see brands like Hastings, Wix, NAPA, and Baldwin. You won't see Purolator, FRAM, STP, or Mobil 1. Are there two oil filter markets? Is one geared toward consumers and their dollars with fancy filters with metalflake paint jobs, 99% efficiency claims, and big price tags? Is the other segment aimed at serious, no-nonsense mechanics where predictable performance and rock solid reliability are paramount? Are BITOG'ers in the right camp?
