Archoil AR6400-D Diesel Fuel System Cleaner utilizes the latest and most powerful fluid technology to deliver a cleaning service to the key fuel system components - injectors, DPFs, turbos and EGRs.

Experience restored performance, improved fuel economy and smoother idling as a result of cleaning the fuel system with AR6400-D.

AR6400-D does not cure Power Stroke HEUI injector problems (stiction). Please use AR9100 Friction Modifier instead.

Cleans Injectors

  • AR6400-D rapidly removes internal diesel injector deposits (IDID) and carbon build-up from injector tips in all diesel applications
  • AR6400-D ensures correct injector spray patterns, resulting in a more complete combustion and lower emissions for optimized performance
  • Cleaning carried out by using AR6400-D results in more power and efficiency and less frequent regens

Removes Turbo Deposits

  • AR6400-D removes carbon build-up from the turbo. Carbon build-up negatively affects turbo performance and life
  • Carbon and soot deposits restrict movement of the turbine and variable vanes inside the turbo, resulting in turbo lag and less boost
  • AR6400-D prevents the accumulation of carbon to reduce excess heat and wear and avoid premature failure of the turbo

Reduces DPF Deposits

  • AR6400-D improves combustion which reduces carbon, soot and particulate exhaust emissions
  • AR6400-D cleans soot and carbon deposits from the DPF
  • Reduction in carbon and soot build-up will reduce regenerations, prevent performance loss and potential engine damage from clogged DPFs

AR6400 Frequently Asked Questions

How much diesel does one 12 oz AR6400-D bottle treat?

AR6400-D is formulated to treat up to 40 gallons of diesel with maximum results. AR6400-D is less effective when added to more than 40 gallons.

What's the difference between AR6400-D and AR6500?

A small amount of AR6500 Diesel Treatment is added to every tank of fuel to boost performance, ensure diesel quality and protect the fuel system from wear, deposit formation and corrosion. AR6400-D is designed to be added in large doses to remove existing deposits from your fuel system and engine. We recommend using AR6500 at every fill-up and using AR6400-D every 3,000 – 5,000 miles.

I am currently using AR6500 and my vehicle is running fine. Will there be any benefit to using AR6400-D?

Removing deposits which have built up over time from diesel engines will restore power and fuel economy which has been degraded by deposit formation. Using a fuel system and engine cleaner regularly will maintain optimum fuel economy and power. AR6500 Diesel Treatment is a maintenance product and will help keep your fuel system clean in between treatments. In order to remove heavy deposits the higher concentration of detergent offered by AR6400-D Diesel Fuel System Cleaner is necessary.

Can I use AR6400-D at the same time as AR6500?

Yes, you can use AR6400-D at the same time as AR6500

Can AR6400-D be used in my vehicle?

AR6400-D is suitable for all diesel vehicles, including newer systems such as High Pressure Common Rail.

wish i used this stuff years ago

I noticed a big difference in the idle and starts of my 02 7.3. I had changed the o-rings and seals on the injectors about 3-4 months prior to using this product. I had zero smoke on start up as i fixed it with injector seals. but it would still idle a little weird every now and then. after a few miles i could smell the Additive in the exhaust and with in 25 miles of it being in there it was quieter and smoother.

Great product

I have been using archoil since i had my 2007 f250 6.0. I now own a 2017 Nissan XD with the 5.0 Cummins. I immediately went to the internet and purchased archoil additives for my fuel and oil. The products are far super to any others.

Ok

I have a 2006 F-350. Just had the heads replaced. Thought I would try this. I'm looking for better fuel mileage. Went thru 1 tank of fuel and got no change. On the 2nd tank and see a little improvement. My truck is a crewcab long bed. I have done the EGR and Cat. delete. It has a K & N cold air intake. Any suggestions would be great.
