Cousins truck, SRW F350 Longbed 4x4. He bought it used with 97k and as of today when I changed the oil it had 106k. He just started a new business and he and his wife are expecting a child so Im trying to help him by getting him decently priced quality oil and filter. Last oil change was Rotella 15W40, this oil change I used Supertech 15W40 (states on bottle it meets Ford 171 current spec) and a Napa Gold 7151, which I get at a discount. Since it still has emissions intact, Ill change it every 6k miles, and once we delete it Ill extend the oci with a UOA. Does this sound like a sound plan?
