i know becasue the ac pump is attached to the low speed on my E-fan, and i can hear when it comes on.
with that cleared up, lets focus on things like airflow, engine efficiency and fuel types.
No, the hamburger you just had for lunch wont cost you 1mpg, but your heavy foot will.
simple rules:
reduce drag/friction ~ wash your truck, grease things, change fluids, close up gaps that cause drag, check tire preasure, check bearings, brake drag.
reduce weight ~ clean out your truck, remove spare tire, use lightweight tonneau.
reduce consumption ~ give it less gas to start, stop slower, drive like you 95 and a cops riding your ass (awesome way to not get tickets and great MPG ~ WIN/WIN), allow more air into the engine, reduce the work the engine has to do to move air out.
stop putting 35's on your trucks factory gearing and saying
stop racing civics (#1 MPG problem)
and for goodness sake, stop complaining.
