There are lots of them out there and they need to be squashed before they become "truth." So in the interest of science, our well being and the ADV debate team I will make the first entry. Are stainless steel oil filters as good or better than standard paper element oil filters ? The following is a quote from Scotts website http://www.scottsperformance.com/faq.php "4) How does this type of filtration compare to paper filters? We sent three common brands of paper filter material off to have them tested for the smallest and largest sized particles that would pass through the material. We sent the material off with no names, just numbers for identification so the lab wouldn�t have any idea who�s filter they were testing. The results we got back showed that the smallest particle the three would catch ranged between 9 and 20 microns. The LARGEST particle the three would allow to pass through the material ranged from 56 to 300+ microns. Paper filters are rated on an average of what they will let pass, so each of these three would each be rated at numbers that are somewhere between their individual extremes. The medical grade stainless steel cloth that we use is rated at an absolute 35 microns, meaning nothing larger than 35 microns should pass through the material. This �absolute� rating is important because this type of filter material is also used in medical applications like blood filtration. Bottom line is paper is rated differently than the stainless cloth (average vs. absolute), and either one works to filter stuff out of your oil. Personally I like the idea of keeping the big stuff out of the engine." To me the above is very confusing with their "9 and 20 microns" and "56 to 300+ microns" and "absolute 35 microns" all meant to confuse you the buyer IMO. They avoid concrete facts, evidence and statements. I am going to show some photos which are facts and evidence of why YOU SHOULD NEVER RUN A STAINLESS STEEL OIL FILTER IN YOUR ENGINE IF YOU WANT IT TO ACTUALLY FILTER THE OIL, AND WHY YOU SHOULD STICK WITH PAPER FILTERS - Well just as soon as my camera battery gets charged.
