St. Lucie County Sheriff Mascara announces results of Hydro 4000 test
On June 12, St. Lucie County Sheriff's Office vehicle maintenance mechanics installed a device on a squad car in hopes that it would improve gas mileage.

The device was deactivated Aug. 6 after it was clear that there were no improvements in gas mileage, according to Sheriff Ken J. Mascara.

“The squad car averaged 14.3 miles per gallon before the test and 13.4 for the test period,” Sheriff Mascara said. “Our mechanics believe that this difference was insignificant and could have resulted from normal fluctuations in gas mileage depending on the calls handled by the deputy who drove the test car.”

Sheriff Mascara said: “We feel the device is not conducive to law enforcement use. It is most suitable with steady, constant driving, and not the rapid acceleration and deceleration that characterizes law enforcement patrol driving. The manner in which a deputy drives, with idling time and periods of emergency response did not lead to positive results.”

Sheriff Mascara said: “The agency purchased the test device with the proceeds of drug seizures and not taxpayer dollars. The Sheriff's Office has downsized its non-law-enforcement cars to improve gas efficiency and save taxpayer dollars. When a local news organization reported positive results with the Hydro 4000, we thought it was worthwhile to take a closer look at the device. We will continue to look for ways to save money in the use of our vehicles.”
