I currently have 50K miles on a wire backed Fram Ultra 7317 filter.
I don’t drain and reinstall this Ultra oil filter cause I don’t want to disturb gasket integrity.
Every 20K miles will run cheap Dino oil for 30 seconds to get all the ‘dirty’ oil out of the filter. Then re-drain oil and refill with 4.8 quarts of new oil.
This will be for the BITOG record books at 80K when I finally take off. Maybe try for 100K miles ?
I wonder if Fram engineering team be interested in getting their hands on it for lab analysis….. or I pay for filter analysis ?
