I got the AAP Quaker State Ultimate Durability oil change special last month X2 for cheaper than I could buy the oil alone at Walmart, so I have 2 Purolator L10111 (if the size matters). I know they sometimes tear. Would you use them for a reasonable OCI, or throw them out? What are the risks? I know that Purolators are good filters when they don't tear, with metal end caps and such. I prefer WIX, but don't know what to do with these. What do you think? I mean they're $3 at Walmart so no big deal to throw them away.
