False, the EDC kits are supper effecient and they only run for a short time. Its not like a/c where you have it running for hours at a time. Its on at say 110psi and off at 200psi, I have never experienced any lose in mpg on any of my trucks or customers rides for that matter. When an EDC can be applied I personally think they are the best way to go, but thats my .02$.
