Looking for advice here. My employer took delivery of a new 2020 F250 with a 6.2l in January. This truck will see 15-20k miles in a year with half or more put on in June and July towing an 18 foot enclosed trailer with equipment and spare parts to support our buying stations. I did the first oci at 2500 miles with MC Syn Blend 5w30 and FL820S. We serviced again at 7500 miles and anticipate a 5000 mile oci. I am wanting to go to Schaeffer full synthetic between 15 and 20k miles whenever that OCI happens. So here’s the question: Wix or Wix XP filter? We religiously run Wix on everything from pickups to forklifts to OTR trucks even our production air compressors. For the record, we don’t get rid of anything. The old shop truck has 335k miles on it and the warehouse truck is at 320k. I have to pick quality parts to keep this alive for many years to come. TIA
