My brother has been using the Purolator Boss filters on his car. He changed the oil in January, and then yesterday. I looked over the filters, hoping to find nothing wrong or out of the ordinary, but, I found a couple things.
I cut open the filter from January and found the anti-drain back valve cracked. It looked fine, but when I picked it up and flexed it, that was when I discovered the cracks and splits in it.
The slots in the center tube were open in this one. I was surprised by the media. There wasn't really any spacing between the pleats. Purolator packed it so full of media that there wasn't any space between the pleats. I tried moving them with my thumb, they didn't want to budge. I guess that is a good thing? Don't have to worry about wavy pleats that way!
The filter from last night, I have not cut it open yet, but, looking down into it, the slots of the center tube are barely open. They are just slits. The oil filter from January were open compared to this one. Some of them didn't look like they were open at all. I can't imagine how well the oil was flowing through these tiny slits.
I am very disappointed with Purolator. I hope they get their act together and fix this issues. We were using the older blue, synthetic filters, and I thought they were good filters. Purolator is making me leery about using any of their new products as of now. I hope they work out the issues and start producing good products again.
