Here's the F150 with the 5.0L. Data from 408 trucks with 10 million miles. No data on the 2019, but is it any different than the 2018 or 2017?

And note that usage conditions, or application, greatly affect fuel mileage. However, it also turns out that once you collect the data it follows a normal distribution (i.e. bell curve). Again, most people will be at or near the peak of the curve. Most likely due to similar driving behavior and vehicle application. If not, you're an outlier.
