What bumper? The mod bumper (and a lot of other offroad bumpers) has some aerodynamic issues.

4500 miles on my 2.3 big bend manual transmission. usually around 18-19MPG city, 24-27 highway. 22 combined.

current lifetime MPG is 22.5

Basesquatch 2.7, automatic, soft top, 4 door with a 1" level. I average 17 miles per gallon and run 92 octane.

I am going to try Premium Fuel for a tank full to see if mileage changes. I had gotten a warning that the Bronco was 50 miles from empty, before the last tank was filled.

I really don’t see the mod bumper having much effect on the aerodynamics of the Bronco. Are you thinking that the openings on the sides catch a lot of air? I wonder if filling them with fog lights would improve it at all.

Yeah the pockets are the main thing. Airflow gets pretty messy going into the pocket and through the wheel well. The large gap between the bumper and body work is an opportunity too.

I was looking at some fog lights from Amazon. Don't know if I will try and squeeze three individual lights into that slot or a 7-9 inch bar.
