Testing high electrical use vs. Mpg
It's commonly known that your cars alternator increase its output and therefore load on the engine as it keeps up on the electrical demand of the car.
Has anyone tested mpg with high electrical load vs low load?
In early winter mornings, I'm driving with the heated seat on, rear defroster, blower on high, highbeams on...
I'm just curious to know what effect this has on my mpg.
As a side note, my car has electric power steering...that motor must be drawing a lot of current at low speeds!
I'm wondering about a cutoff switch to disable it at highway speeds...?
