This is an option for a stocking filter at my shop. This number is the cross for a Motorcraft Fl500s. Solid construction and thick media. Hastings will not recommend a mileage for use but says it's warranted for any factory oci that the particular filter is recommended for. My only concern is the media spacing at the glued seem. Looks like the same problem motorcraft has. Maybe the thicker media will make up for it.
