Has any reading been done over on
- Bob is the Oil Guy Some points or questions above I've seen discussed over the past eight years over there. There is some quite good stuff on oil filter material, construction and "action". There may be some noise to filter out (sheer number of threads), but one can get a good start by reading through the posts & articles by "Molakule". (And others: GeorgeCLS, Johnny, Haas, etc.) No one may be the guru, but there may be considerations raised that are of benefit.
