Its central tube,mineral clay formation consists of a lot of mineral elements refined from the nature that can absorb energy from its surrounding at normal temperature and release energy in the form of infrared rays. It generates a specific light wavelength having the frequency similar to that of fuel. When fuel passes through,far infrared rays cause resonance with fuel molecules. It activates and ionizes fuel molecules in the fuel lines thus causing the fuel molecules to vibrate rapidly against each at 64,000 vibrations per seconds. As the result,cluster of fuel molecules break into more tiny molecules that enable more intake of oxygen and combustion becomes more efficient and more complete at lower ignition temperature,therefore,increase mileage and horsepower of engine and reduce air pollution drastically. It also helps to clean –up carbon built – up in the engine and hence,prolong the life span of the engine with less maintenance.
Dispersed Fuel Molecules that carries negative ions can mix with oxygen molecules easily. This ensures a more complete combustion,more power and reduce toxic emission drastically.

This is a laughable explanation. You don't need a degree in physics to tell that this is complete BS; In addition, I have trouble believing that some external party can invent fuel saving mechanisms which your car manufacturer apparently hasn't discovered, yet they spend billions on R&D. If this was for real, it would be appearing in some models already.
