The fuel conditioner ionizer, interposed in a fuel line leading to an engine or a furnace, includes a housing, an inlet sealed to the fuel supply line and an outlet sealed to the fuel line leading to the engine or furnace. A plurality of metal wire strands from the plurality of different metals is disposed in the housing. Angular and directional fuel flow is generated by a fluid mixing device mounted in the housing. The mixer is a stationary turbine with a plurality of radially extending blades, circumferentially disposed in the housing. Improvements include an annular ring holding the blades, a central hub in the ring and additional or secondary flow directing blades. A cone or frustoconical segment may be attached or be part of the forward end of the hub to direct the fuel radially outward.
