AR6400-D Diesel Fuel System Cleaner

Archoil's AR6400-D delivers a powerful and thorough cleaning service to the fuel system to quickly solve issues associated with carbon build-up and clogged injectors and should be used every 5,000 miles.

"Archoil AR6400-D Diesel Fuel System Cleaner is absolutely crucial to the longevity of the engine and the fuel injection system in all Power Strokes." - Bill Hewitt

RESTORE DIESEL INJECTORS

Archoil AR6400-D rapidly removes internal diesel injector deposits and build-up from injector tips. This ensures correct injector spray patterns for a more complete combustion and lower emissions for optimized performance.

REMOVE TURBO DEPOSITS

AR6400-D clears the turbine and variable vanes of soot and carbon, reducing turbo lag and restoring boost. This reduces excess heat and wear, avoiding premature failure of the turbo.

REDUCE DPF DEPOSITS

AR6400-D improves combustion to reduce carbon, soot and particulate exhaust emissions as well as removing heavy deposits from the DPF. This reduces regen frequency and prevents performance loss and potential engine damage

Noticeable improvement!!

Absolutely nothing to hate about Archoil!! Excellent products for todays diesel fuels. It’s a must for CP4’s to have the fuel additives; the 6400-D, and change your fuel filters every other oil change and say a prayer and your CP4 should be good for 100k miles when you should probably replace it to save you from the issues if it does fail. Archoil gives you the best advantages to saving your Diesel engine! Can’t go wrong with Archoil!
