Hot Shot's Secret® Diesel ExtremeTM Clean & Boost is a fully formulated and concentrated fuel system cleaner and engine cleaner. Designed to remove deposits and improve the performance of all types of diesel engines, from semi-trucks to RV's, this diesel injector cleaner removes all internal diesel injector deposits (IDID's) and external diesel injector deposits (EDID's) as well as waxy and polymeric deposits that can clog the fuel filter. Our powerful diesel additive and fuel cleaner cleans out injector tips, cylinders, fuel lines and tanks, all while dispersing moisture to deliver a more efficient system. Once the fuel system is clean, Diesel ExtremeTM contains several premium additives to enhance performance. A cetane boost can improve cetane ratings by 7 points for better combustibility, fuel economy and horsepower. With improved combustibility, you can reduce the number of diesel particulate filter (DPF) regeneration cycles required. Use 8 oz per 20 gallons of diesel fuel.
