LIQUI MOLY – LIQUI MOLY Fuel System Additives - 0.035-0.5 L, including Speed Tec Gasoline, Motorbike Engine Flush, Motorbike 4T Bike-Additive, Truck Series Complete Fuel and Diesel System Cleaners, and Pro-Line Injector & Glow Plug Grease. Small bottles, measurable results. This is the treatment side of the range, sized from 35g tubes up to 500mL cans so a single tank or a single service gets exactly the right dose. Injectors, intake valves and combustion chambers collect deposits from normal running, and deposits change spray pattern, which changes mixture, which quietly costs throttle response and fuel economy long before a warning light appears. Speed Tec Gasoline is a performance-oriented pour-in aimed at sharper response and cleaner combustion, while the Complete Fuel System Cleaner and Complete Diesel System Cleaner in the Truck Series work through the injectors and pump to clear that build-up. On bikes, Motorbike 4T Bike-Additive suits machines that sit between rides and sip fuel slowly, and Motorbike Engine Flush is circulated before an oil change to carry sludge out with the old oil instead of leaving it behind.
