If there is a knock on truck and gas it is starting tbn, it looks more like a conventional oil as far as starting tbn, but that filter is one of the best filters made, likely you can run it for two oci's with that truck and gas. I like truck and gas, great moly, just doesn't appear to be a long interval oil when the tbn starts at 7. Unless you are all freeway miles, I wouldn't be going past 7500 miles. If it were me, maybe I would set the oci at 5k miles and leave the filter on for 2 oci's.
