[2010civic]

Well my hypermiling has been working well. I finally made it to 41.4 mpg average. I am pleased. I have however hit a plateau where I am. I get 45-46 MPG on the highway and 38-39 city. I came across an article about this technology (HHO) hydrogen injection which says in the article 30-35% increase. The cost of the kits seem very reasonable, and not difficult. Has anybody tried this or familar with it?
