The unique combination of proven PEA technology and the latest additive generation achieves maximum cleaning performance in the combustion chamber, in and around the injector tip, and in the entire fuel system. Furthermore, DIJectron stops the formation of new deposits so that complex injector systems always work at the highest efficiency. Regular use of DIJectron significantly reduces the risk of engine damage caused by Low-Speed Pre-Ignition (LSPI), optimizes exhaust gas emissions, and protects the fuel system from corrosion. LIQUI MOLY recommends DIJectron for modern 4-stroke gasoline direct injection (GDI) engines. Contents (300 mL) are sufficient for 50–70 Liters (13-18 gallons) of fuel. For the best results and long-term effect, add DIJectron to the fuel tank every 4.000 km (2400 miles).
