Drained the Maxima today and changed the oil for some fresh 5W30 Super Tech conventional. I lost track of the mileage on this OCI, and probably have closer to 6K than 5. I replaced the Purolator L14610 out for a PH7317 Fram Extra Guard OCOD. I opened the Puro with a hammer and gasket scraper and only found good things. Please excuse the damage I caused myself. Straight, well spaced pleats with no tearing.
