Purolator Oil Filter Review Conclusion
So we have done our research and know what Purolator wants us to know about their oil filters through their marketing efforts. However, we have also read a lot of reviews and feedback from people who have their own experience. As with most products and their reviews, you will have good and bad. Purolator oil filters definitely have some bad reviews. Some reviewers are experiencing issues with the filter media tearing. Either due to not enough media, brittle media or unevenly spaced pleats. We have seen several examples of these tears after people have cut open their used Purolator oil filter for extensive study and review. There has also been reports the the anti drain back valve having cuts in them. At the same time though, there are plenty of people who swear by them and use them exclusively without issue.
