AR6400-D is not a standard fuel system and engine cleaner. AR6400-D has been specifically formulated to meet the needs of modern diesel vehicles by removing particulate matter (soot) buildup from post combustion systems. Use AR6400-D to help remedy blocked DPFs, dirty EGR systems and stuck wastegates and variable turbochargers, all of which cause drivability issues. AR6400-D's detergents remove deposits in the fuel system, on injectors and in the combustion chamber helping restore power and fuel efficiency. AR6400-D also boosts cetane. Use AR6400-D every 5,000 miles or as required. For best results between treatments use AR6200 Fuel Modification Complex at every fill-up. Long term use of AR6200 should eliminate the need for AR6400-D. AR6400-D Fuel System Cleaner is NOT the appropriate product to remedy PowerStroke (HEUI) injector issues. Instead, please use Archoil AR9100 to eliminate PowerStroke 6.0 & 7.3 (HEUI) injector problems.
