Anecdotal MPG claims ignore the fact that different people have different driving habits and live in different areas with different speed limits, elevations, terrain, etc.

Right now on Fuelly using real world data the 2.5 is doing about 1.5-2 MPG better than the 3.6, which is significant. However, there are currently only 9 vehicles reporting so I wouldn't read too far into that yet.

Point being, it's too early to make definitive claims about the 2.5. Unless somebody has owned both, like Hawkeye1, trying to make comparisons is pointless. Their claim lines up with what I have experienced with my F-150s, with the turbos being significantly more efficient in city driving, provided they are driven conservatively.
