The Liqui Moly Pro-Line Direct Injection Cleaner is used to remove harmful deposits from the fuel system in direct injection petrol engines. It relies on polyetheramine (PEA) technology to deliver a strong cleaning effect, ensuring piston surfaces, combustion chambers and injectors remain free from carbon build-up.Discover the key features of this cleaner:Polyetheramine (PEA) Technology: The formulation uses highly active polyetheramine molecules that dissolve stubborn carbon deposits within the fuel system, improving combustion efficiency and leading to smoother engine operation and consistent power delivery.Combustion Chamber Cleaning: The cleaner targets deposits around pistons and valves, breaking them down and preventing their build-up, which reduces knocking tendencies and helps maintain stable ignition timing for reliable performance.Low-Speed Pre-Ignition (LSPI) Protection: By reducing deposits that contribute to LSPI, the cleaner lowers the chance of engine damage at low speeds, supporting engine durability and long-term reliability.Fuel Tank Application: The liquid is designed to be added directly into the fuel tank where it disperses evenly, ensuring thorough treatment of up to 50 litres of fuel for convenient use without specialised tools.Using this cleaner helps you restore fuel system cleanliness, improve combustion stability and reduce risks linked with carbon build-up. It provides a smart choice for maintaining the reliability and efficiency of your petrol engine. Having it in your garage setup gives you a straightforward way to keep your vehicle running smoothly and protect key components over time.120ml Bottle - Treats up to 50 litres of fuelTechnical Data Sheet
