My 2005 Honda Civic was rated 31/37 for gas mileage. I have a long commute for work and I find I typically get 34-35 mpg, a little less after an oil change (it likes older oil). Rarely do I ever get 37 mpg.

Then I started putting orgonite in my car.

The first time I got 40 mpg (!!!) which has NEVER happened.

Since then, getting 37 mpg has become the norm, not the exception. The time I got 40 mpg I had my wife's orgonite in there, a larger piece with hand-picked crystals that included amethyst and malechite, all of which she judged as having the best energy of what I had onhand. It had about 20% brass shavings, 70% aluminum and about 10% copper set in a clear resin. This was in addition to 4 TBs interspersed in the car.

I've "threatened" my wife I would put it back in the car so I can get back to 40 mpg. In any case, consistently getting the top-end mpg is definitely a noticeable improvement. I suggest everyone give it a try and see what improvement you can get.
