Nowadays engines are designed to produce high performance in low fuel consumption with a fuel system that has not lost its function and clean fuel. The basic requirement for problem-free operation of the engine is a healthy fuel system and clean fuel. In order for the fuel system to work healthily and for the engine to produce more power with less fuel, the fuel circulating in the system must be clean. 50% of the fuels used don't meet the ISO 4406 18/16/13 (2500 particles / 1ml / 4µm ©) fuel cleaning standard. Clean fuel is found in the fuels used; dirt (dust, rust, organic pollutants) and water with high productivity. The biggest expense while driving is fuel consumption, making this consumption efficient and protecting the system is an important gain. Fuel derivatives and additives to be used other than fuel type recommended by the vehicle manufacturer lead to failure of healthy filtration and damage the system.
