Why would one put a used oil filter on their vehicle? It looks like the filter did it's job and kept out the contaminates. Missapplication? What is with the hole in the shoes?
I don't think anyone was consdering installing a USED filter on their vehicle. I think his intent was to show what the filter did and didn't do while it was installed. As far as these studies go, Anyone and everyone has cut open unsued filters. I would like to see someone and more of ones cut open after being used and see how they held up. Cut open the media like this guy did and see what was trapped in it. Of course to get a fair comparison, it should probably be done on the same engine with the same brand oil, and same amount of mileage between intervals. I know I wouldn't be happy to cut one open and see a collapesed element.
The thing is, even if you did that it still wouldn't be a "fair" comparison, because each time the oil and filter was changed you'd have more miles on the engine. Let's say you start the comparison after the first 10,000 miles are on the engine... Let's also say you'll change the oil and filter every 3,000 miles, and that, to try and keep things equal, the vehicle will be run on a track, so all the mileage is the same. Okay, now, if you do that and have 10 different filters to test, the first filter will have been used on a car with just 13,000 miles (when removed), but the last one will have been on the car from 40,000-43,000 miles. It could be argued that the first filter didn't have as much contamination to deal with as the last filter did, because the engine was more "worn" by that time.
Yeah, nit-picking I know, but it could make a difference in the results.
