You can probably thank a person by the name of Russ W. Knise for the misconceptions of Fram oil filters.
In 1996 Mr. Knise published a “study” of oil filters which resulted in his mass condemnation of Fram filters and it began a faithful following of junk science believers. In the first version of this “study” he deconstructed various oil filter brands, included pictures of parts, and made judgement (guesses, really) values on function based on the physical appraisal of those parts. His invective-filled diatribe was almost completely reserved for one manufacturer, Fram. His evaluation was based solely on material and assembly construction, with especially crude judgement of the “paper” end-caps used by Fram.
In reality this “study” was absent any empirical evidence to the claimed inefficiencies of the material, function, or design. In fact, the most important aspect of oil filter design, contaminant elimination, was never tested or evaluated at all, except by his cursory eyeball examination of the material.
After being called out for his less than sophomoric “study” which he earlier attempted to claim was research, he significantly changed the grammar, removing the grade school use of invectives like “junk” and “crap” as descriptives, and presenting what appeared to be a more professional sounding document. In the subsequent revision he included disclaimers, such as “WARNING,” “These pages are NOT to be taken as gospel,” which some claim was for legal reasons.
Anybody can make a claim or state an opinion on the Internet, or make a Youtube video (those attending the Church of Scotty Kilmer should take note). The kind of information Burla has supplied seems to have credible analysis based on actual testing and a verifiable source.
Right from the start there were people who questioned his motives, and it can be found within the second revision: a claim that a Fram filter damaged his engine.
I and a few others tried to have a dialog with Mr. Knise, to no avail. The last time I checked his website was not active.
