Also from Australia:
"The independent testing, by Vipac Engineers and Scientists Ltd, was conducted in accordance with the Australian Standard relating to devices claimed to reduce fuel consumption and exhaust emissions. The tests involved fitting a Ford Falcon and Toyota Hiace, both using unleaded petrol, with a Fitch Fuel Catalyst.
Analysis of the results focused on the difference in fuel consumption and exhaust emissions between the vehicles before the device was fitted and then after the device was fitted.
Mr Haley said the test showed no change in fuel consumption in either of the two test vehicles when fitted with the fuel saving device."

"Investigators targeted six products sold in Australia
that claimed to reduce fuel consumption in motor
vehicles. The companies were required to provide
independent scientific evidence to prove that their
products did what they claimed. None of the
companies were able to satisfactorily substantiate
their claims. Four of these products were removed
from the marketplace: Magnoflow, Prozone, MPGCAPS
and FuelMAX/Super FuelMAX. The other two
devices - Fuelmate and the Fitch Fuel Catalyst -
deleted unsubstantiated claims from their website
and promotional material, including promises that
these products could ‘save consumers up to 25%
better fuel economy’ and ‘from 5-12% fuel
savings’."
