Hot Shot's Secret Diesel Extreme Clean & Boost is a fully formulated and concentrated fuel system cleaner and cetane booster. 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 demulsifying moisture to deliver a more efficient system. Once the fuel system is clean, Diesel Extreme 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. Add during fuel up and run every 6,000 miles for best results. For use in all diesel engines. Use one treatment of Diesel Extreme every 6000 miles.
