25/25 is optimistic. I manage a fleet of 50 1500 Chevys and F series Ford’s. I picked 3 highway trucks - 3.5 eco boost, 5.0 coyote, and 6.7 powerstroke. Over 30,000 miles each, average was 16.93, 17.72, and 16.26 respectively. Eco boosts can achieve higher MPGs, but when pushed even slightly, MPGs drop significantly.
