Principle of fuel saving: When fuel is flowing to the fuel saver, it magnetises fuel molecule and makes the molecule temporarily into cathode. Fuel burning will be more efficient in engine while reducing carbon. The unit can improve your fuel mileage an average of 10%-20%. The unit gives you high test performance and lets low carbon monoxide. The gauss value has 12000 gauss. Increase mileage(Fuel saving of up to 25%) Pays for itself within a couple of months from your fuel's bill Your engine will last much longer. Reduces carbon monoxide emission Uni-directional magnet. It does not interfere with any other electrical device Works on petrol or diesel engines Environmental friendly! Maintenance Free and One time purchase Install in less than 5 minutes with no tools needed!!! Does not affect vehicle warranty! Can easily be transferred to another vehicle Suitable for both gasoline and diesel engine How it works? Fuels are mainly made up of hydrocarbons.With the use of the Super Fuel Saver, fuels change their magnetization orientation as they cross a magnetic field in the opposite direction of the external magnetic field.At the same time,hydrocarbon molecules change their configuration which reduces the intermolecular attraction forces. The fuel saver finely divides and distributes the particles evenly thus making the combustion more efficient. The fact that Carbon and Oxygen have opposite magnetic polarity by using the Super Fuel Saver both Carbon and Oxygen are easily fused together producing a better and efficient combustion. As a result of the fusion of fuel and air, the engine works more efficiently generating greater power, reducing the consumption of fuel, and also the hydrocarbons(HC), carbon monoxide (CO) and nitrogen oxide which emanate from the exhaust.
