It is cost-effective to add or trade to a small car as a commuter, or are you locked into the Ranger?
Otherwise:
- Lose the lift and lower if you can
- Go with the smallest tire/wheel combo
- Calculate spoiler placement carefully
- Consider frontal and side aero treatments
Step #1: Reduce top speed and learn driving techniques to maximize fuel economy.
Figure shift points for your automatic to either lift-to-shift or allow the vehicle to do so "automatically". Best FE to you.
