So, I guess you need to have a college degree to open up some oil filters and see what is inside? Then when you do that to a range of filters, you can’t compare one brand to another? You also need to be a material scientist to point out which filters come with rust in them?I watched it up to where he started tearing the end cap apart. This reviewer is evaluating oil filter material and design, but he's has not told us about his qualifications. Does he have any engineering and design credentials pertaining to oil filter manufacturing? As far as I can tell, his viewpoint is strictly from a layman's point of view, not a materials engineering point of view. And there's nothing in the video about how the filters do the job they were made for, only a critique of construction material.
Construction materials are designed to function in a given environment, and they often appear to be inappropriate or unsuitable when viewed outside of their intended environment. In this video, the filter material appeared to be dry; it had not been used yet. What happens to that material when it's exposed to hot engine oil? Again, it's made from essentially the same as the filtration media, which clearly holds together despite the enormous pressure of oil being forced through it. Why would you expect the end cap material to fall apart but not the filtration media?
If you look at the shelves in just about any auto supply store you'll see that Fram filters outnumber all other manufacturers combined. I contend that with so many filters in operation there is more than enough real-world use data available from which to draw conclusions about product suitability. It seems to me if people were experiencing problems with these filters the word would be out--where are the lawsuits?
To convince me that Fram filters don't work for their intended purpose I need to see data from a controlled study, not the opinion of someone who appears to be unqualified to evaluate construction material and methods.
The whole point of posting that video was to contradict your experience of seeing oil filters being made in a factory that all had the same internals. While I’m sure there are filters out there that are exactly the same except for the printing on the outside, in terms of the major brands there are differences.
I personally would prefer to use things that are better than meeting the minimum spec. That could be a waste of money, but using full synthetic oil and an oil filter that has higher quality internal pieces is part of the reasoning for doing my own service. Even when using more expensive stuff, I pay less than someone paying a mechanic.
The end cap of the Fram filter that was falling apart was not what I believe is a combination of fiber and resin. Nor was it made from the same material as the filter media. Here is what the Mann filter looks like and I would believe is a combination of fiber and resin, it may also be of the same material as the filter media (not that makes any difference).
