Love the commercials.
I figured the gas milage shouldn't be that bad. I am honestly thinking there is a small fuel leak somewhere. Did you see the mention of the "air bubble" that occurs? Everytime you open the gas cap air comes rushing out. One time the license plat was rattling when the car was iding from the pressure of the gas cap. I figure air is coming in and gas is going out.
I have been getting 15 or so mpg.
Maybe I'll check out the Nest for him and see if I can get some ideas.
