OK guys its 'Test Time'...if two of you can agree to do it. Take two filters say 'Brand 'A' & 'Brand 'X'. Weigh each filter before fitting,run say 3,000 and remove the filter,let it drain out oil overnight then weigh it again to see the weight of the crud it has over 3,000 miles....then cut it open and examin the element.......my 2 cents...what's yours ???
