Complex diesel fuel additive. It has cleaning, dispersing and protecting properties. It prevents deposits in the fuel system, removes soot from valves and the combustion chamber, normalizes fuel consumption and exhaust values, protects all the fuel system from corrosion. It cleans catalysts and restores efficient operation of the lambda-probe (oxygen sensor). It protects the fuel pump, injector needles, area of cylinders/pistons and outlet valves. It increases the cetane number, ensures engine efficiency and reliability.
