1) Increased mileage per gallon of fuel consumed (typically ~15% with refined fuels) |
2) Increased power, variously expressed as lower idle speed, earlier transition from lower to higher gears, faster acceleration, greater pulling power, etc. |
3) Reduced emissions of carbon particulates (soot), unburnt hydrocarbons and carbon monoxide |
4) Reversal of previously accumulated carbon deposits within engine and tail pipe, allowing for further improvements in engine performance over time |
5) Reduced separation of water from fuel with less growth of hydrocarbon-metabolizing, contaminating bacteria |
6) Less deterioration of fuel during long-term storage |
