FUEL AND OIL

HHO is needed. The amount of HHO will vary depending on the size and engine capacity, • Horsepower is increased between 3% and 12% depending on the engine and the grade of diesel used, • HHO improves and cleans heavily carbonized engines. In some long term tests fuel efficiency improved between 10% and 20% by cleaning the engine. Up to 80% of this efficiency was maintained after removing the device, and • HHO works best when the vehicle is travelling at certain speed or above. There is no benefit when the engine is idling. “The petrol price has shown an average increase of 13% Y-o-Y since 2003,” concluded Price. “Even with recent price reductions, and with fuel contributing more than 45% of total fleet costs, the use of alternative fuels offer a viable solution to reduce costs as well as carbon emissions.”
