any of those gas savers work for anyone on here?

I tried a bicycle... you can be as heavy on the padal all you want!! LOL... most of that stuff is just gimicks. My dad a and I bought some stuff from Liberty fuels that is supposed to increase gas mileage and power, etc.... he used it on a trip from Washington to California, lots of different types of driving and could not tell any difference using it or not. That was on a Chevy Astro van.... I would say, keeping your foot out of it a bit helps a lot... I drive faster but smoother than my wife and I actually get better mileage in my cuda than she does.... I can tell when she has been driving it, I have to fill up sooner!!
