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

This stuff works. Period

My 2019 Ford F250 with 100,800 miles had a check engine light come on with code P0170 and P0402. After researching these codes, one of the possible causes could be a carbon-covered EGR temperature sensor. Instead of just replacing or cleaning the sensor, I decided to try AR6400-D to reduce the carbon. The result after the 1st bottle was added, the check engine light coming on then off. After the 2nd bottle the check engine light is off and codes have been cleared. This stuff saved me a trip to dealer and what could have been hundreds of dollars that wouldn't have addressed the real cause of cleaning the carbon through out the engine

Great Product, Bad Shipping Experience

I've used this product for several years and am most satisfied with the results. It cleaned whatever was causing the CEL (most likely the 2nd pass of the EGR cooling HX), which has since cleared and not returned. However, this time my shipment sat in a post office in CT for 3 weeks, and it took me 3 e-mails and 2 phone calls to actually connect with a human who immediately corrected the problem with a new shipment. That's almost more patience than I'm going to give if it happens again.
