Although I have been known as a skeptic of free energy and high mileage claims, I currently have a hydrogen boost device installed on my car - the following link is a summary of my testing done on this device:

The device is not working now - it appeared to dissolve its self in a longer test.   I gave the inventor multiple chances to get it working.   I was in the process of negotiating giving them another chance to get it working and posted data to date.   This got the company owner very angry at me - he says my improper maintenance caused it to not work or be destroyed and has threatened a lawsuit if I don't take down the page.    I don't think I want to help any more hydrogen boost people do tests.   Skeptics say some of my high mileage seen on some short tests were a result of poor protocol on my part.
