I was speaking with an owner from a oil change shop who stated that most oil filters start to bypass at approx. 4,000 miles due to clogged filter media. I understand that he has an obvious bias and his statement was a broad generalization when in fact, there are many variables that come in to play. However, in general terms, how long should a filter be used?
Secondly, do manufacturers take oil filter life into account when determing the length of OCI's?
Thank you.
