Test your favorite HHO machine if effective or NOT. Park the car, start engine to normal temperature, run to 1500 rpm and hold it there by using tools or wedges. Turn ON your HHO machine. Check the RPM goes up to 1600 or more, it is GOOD. If RPM goes down or the same, your HHO machine is ineffective, useless, and waste of time, effort and money. Any seller will pass this test, BUY their HHO machine. (Forget the driving around wasting more gas, or read On Board Computer Instant MPG).
