here's what i did, i took a soup can, and am running electricity from an old fog light harness through some salt water, or baking soda water. this turns it into hydrogen and oxygen. i then let the intake suck in this mixture of gases. it din't cost me a cent and i get about 20 to 30 more miles per tank. depending on the engine your mileage difference could be better than mine, since i have a big engine in my car to begin with.

before you ask if it creates wear and tear on the engine let me just say that it doesn't. In fact, it helps clean up the carbon buildup!!
