“Good day, I learned about HHO generators and the possibility of driving cheaper from a friend who has been using it for about a year and praised it very much. I was a little skeptical at first, because he has an older car without any air weight sensors and lambda probes, which I even have two in mine, but in the end I decided and tried it. I also thank you for your willing consultation regarding additional electronic devices for the already mentioned lambda probes. I am satisfied so far, everything works as it should and I save about 15-20 percent of diesel and that’s very good for my very long driving time, and I reckon that the cost of the generator, if it goes like this, will be paid back in a few months. Best regards, Stan, and I’ll certainly recommend it in the future.”
