Gas saving device put to the test again

WPTV.Com of West Palm Beach, Florida has subjected the Hydro 4000, an HHO kit, to further testings.

The unit was first tested back in May, when they installed it in 2000 Dodge Durango and tested it on a dynomometer, a kind of treadmill which helps us measure miles to the gallon. Without the unit on, the truck averaged a measly 9.4 miles to the gallon. With the Hydro 4000 running however, it got an incredible 23.2 miles to the gallon.

This time, they took the Hydro 4000 to the mechanical engineering department at Florida Atlantic University in Boca Raton. For this test, they used a 2001 Chevy Tahoe in good driving condition, which was then tested on a dynomometer at Billet Design in Pompano Beach, a company the university has used for many of their other tests.

For the test they drained all of the fuel out, giving it an empty tank. The team then filled the tank back up with one and a half gallons of gas. The vehicle was put on the dynomometer, and the truck ran at 65 miles an hour until it stalled. It ran 17.7 miles, for an average of 11.8 mpg.

Then they installed the Hydro 4000 on the test vehicle and have the owners drive it for five weeks in normal traffic, after which they tested it again. They again drained all the fuel out, put in one and a half gallons of gas and ran the truck at 65 miles an hour until it stalled. This time, with the Hydro 4000 running, the vehicle ran 19.5 miles before stalling, for about 13 mpg, a 10% increase over the initial test.

Per the truck's owners, the device gave the vehicle more pep and they estimated they got about 17 to 18 mpg from the previous 12 or 13.
