2014 F150 ecoboost using castrol edge 5w30 for a oil change interval of 7,648 miles. Numbers are reported in the image attached. Truck is 93 octane tow tuned with a 180degree t-stat. This oil change interval had over 1.5k miles of towing multiple trailers up to 7k lbs. Lots of cargo weight in the bed of the truck also as I do construction for a living.
