Hot Shot's Secret® Diesel ExtremeTM Clean & Boost is a high-powered solution for diesel engines. This concentrated cleaner targets all diesel engine types, from semi-trucks to RVs, effectively removing internal and external diesel injector deposits (IDID's and EDID's). It clears waxy and polymeric buildups that commonly clog fuel filters. This diesel injector cleaner works on injector tips, cylinders, fuel lines, and tanks, while also dispersing moisture for a more efficient system. Post-cleaning, Diesel ExtremeTM boasts premium additives enhancing performance. A cetane boost can elevate ratings by 7 points, enhancing combustibility, fuel economy, and horsepower. Improved combustibility may reduce diesel particulate filter (DPF) regeneration cycles. Use 8 oz per 20 gallons of diesel for optimal results.
