So during all the wailing here about torn filters, I contacted Purolator... politely... and they got back to me... back and forth... I challenged them to restore my trust. They are trying to do just that.
So the deal is, they sent me filters and return kits for all 3 of my vehicles, I'll use them for one OCI and send them back for a lab analysis. I get free filters and free data and they get a chance to earn my trust back.
There is some minor risk on my part that I'll run a torn filter again. My Honda had a small tear on its Classic and now I'll be running the equivalent PureOne, which has a lower but documented propensity to tear. It's had a Wix for ~ 3K now, I'm going to end that OCI early to get on with the test. I think I'll end the P1 OCI at 5K instead of 7.5 like I usually do. It's getting older and I was thinking about dialing back the OCI from the factory 7.5K to 5K anyway.
So I'm thinking I may do some UOA's or at least one on the Honda. Maybe I need a VOA or a UOA on the last oil drain. Thoughts?
I'm also thinking about non-invasive ways to check for tears, since I cannot cut the can on a filter I'm returning. The only thing I can think of is to stick a very bright light in the center tube and checking the inlet holes for light.
I'll take notes and pics and report back when it's all wrapped up... in about a year.
Sorry! It takes time for tests like this. For now I'll try to answer questions in this thread, except for "how do I get free filters" or Purolator contact info. Everything you need to contact Purolator is already known here.
