I am still using Purolator Oil Filters but, they're old(er) stock. I purchased them, ON SALE, W/Rebate and AAP DISCOUNT CODE#'s, which netted me 12 filters(6 Classic/6 PureONE) all for ~ $15 when all said & done. I still have several filter remaining!
I am working on this filter stash and will & have been cutting open each filter after the OCI is complete. Thus far, I have seen no irregularities with the filter can, gasket, By-Pass Valve, ADBV or it's media.
And too, the media looks better than the "cut open" pictures that we've seen here recently from other members. Meaning, more pleats, straighter media(not all wavey), thicker etc...just better looking!
When this stash is complete, I will then decide what filter(s) I will be using for the vehicles in my signature.
