I am currently running the Amsoil FF flitter on my truck. I don't hate it and it was 2/3 the price of the motor craft filter. When I get too much money, I'm considering running a stainless full flow filter on my truck and just check it every OLM interval, or every bypass filter change. I feel like full flow filters are mainly a backup just in case something weird gets into the oil, especially with a bypass filter system on the truck and a properly functioning engine.
