The Liqui Moly Pro-Line JetClean Fuel System Cleaner is a highly concentrated, ready-to-use professional-grade cleaning fluid designed to deeply restore and protect modern fuel systems. Formulated to remove stubborn deposits from injection systems, intake valves, spark plugs, and combustion chambers, it helps engines run smoother, cleaner, and more efficiently.

By preventing new deposits from forming, this advanced cleaner optimises throttle response, reduces rough idling, improves cold starts, and helps recover lost performance. It also protects the entire fuel system from wear, corrosion, and harmful buildup — ensuring long-term reliability. Cleaner engines burn fuel more efficiently, resulting in lower emissions and reduced fuel consumption.
