Prozone Fuelsaver, The Fuel Saving Device Testimonials - Australia 1997
May 1997 - Australia - UltraTune, Brisbane, Queensland
The Prozone Fuelsaver fuel saving device was tested on a 1993 Ford
Falcon vehicle with a 6-cylinder 4,100cc engine using unleaded petrol
(ULP). The tests were conducted by engine performance specialists UltraTune
of Brisbane, Queensland using a Sun chassis dynamometer and exhaust
gas analyzer. At idle speed, tailpipe emissions of hydrocarbons (HC)
were reduced by more than 60%, whilst carbon monoxide (CO) emissions
were cut by 33%. At 80 kph, an even more dramatic reduction of 95%
was recorded for hydrocarbons.
