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
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.
This is a great product, it was delivered in a timely fashion. Received a nice hat as well. Thanks Archoil !
I don't think it's the archoil I'm pretty sure I have a bad injector but thank you .
First time using this but seems to make cold starting quicker.
I have been using, every other oil change. Truck runs very smooth-2019 Powerstroke. I also try to buy fuel at high usage stations.
