AR6400-D Diesel Fuel System Cleaner rapidly cleans injectors, turbos and DPFs to remove heavy carbon build-up which negatively affects the performance and life of your fuel system. This highly concentrated one-tank treatment restores power, performance and fuel economy.

  • Rapidly clean injector tips and IDIDs
  • Remove carbon and restores turbo function
  • Eliminate DPF build-up and reduce regens
  • Restore power and performance
  • Improve combustion to reduce carbon, soot and particulate exhaust emissions

Injectors suffer performance loss due to nozzle deposits and internal diesel injector deposits (IDIDs). This affects injector spray patterns and leads to inefficient combustion of fuel, resulting in a loss of performance and excessive carbon build-up in the fuel system.

AR6400-D removes heavy deposits from injectors to ensure a correct spray pattern and restore performance.

Carbon build-up on the turbo will restrict movement of the turbine and result in your engine not operating in the way it was designed to. This can cause your engine to over boost or under boost, negatively affecting power and raising the possibility of overheating and engine damage.

AR6400-D clears the turbine and variable vanes of soot and carbon to ensure the turbo operates efficiently.

Deposits in the diesel particulate filter (DPF) restrict exhaust flow, creating an excess of backpressure and causing your engine to coke on excess exhaust. Carbon build-up in the DPF also causes more frequent regens.

Use of AR6400-D removes heavy deposits from the DPF and extends the time between regens.

One 12 oz bottle of AR6400-D treats 40 gallons of diesel fuel.

Add AR6400-D to the fuel tank at the required dosage and then add fuel. Treat 40 gallons for a complete clean. Use every 5,000 miles or as required.

RESTORE YOUR DIESEL FUEL SYSTEM

Clean Diesel Injectors

Injector nozzle deposits (coking) and internal diesel injector deposits (IDIDs) reduce the quality of the spray pattern by reducing the effective flow rate of the nozzle and the atomization of fuel into the combustion chamber.

Reduced atomization from the injection system creates an incomplete or late combustion, creating more deposits and unburnt fuel to leave through the exhaust instead of being converted into maximum power and torque.

AR6400-D rapidly removes IDIDs and carbon build-up from injector tips to:

• Restore performance and correct spray pattern

• Ensure a more complete combustion and reduce further carbon build-up

• Lower emissions

In testing, AR6400-D restored fuel economy 7%.

Prevent Turbo Failure

As deposits form on the exhaust side of your turbo it will start to restrict movement of the turbine and on variable-geometry turbos (VGT) it will restrict and eventually seize the movement of the variable vanes.

These deposits will completely change how your engine was designed to operate, causing your engine to over boost or under boost which reduces power and increases the possibility of overheating and engine damage.

AR6400-D clears the turbo of soot and carbon, reducing turbo lag and boosting throttle response. This reduces excess heat and wear, helping to avoid premature failure of the turbo.

Improve DPF Performance

Carbon deposits in the DPF create a backpressure, causing performance to suffer as exhaust flow is restricted.

This stops the engine working as intended and results in reduced fuel efficiency, a lack of power and in more serious cases, engine failure. DPFs with excessive build-up will also need to regen more frequently.

AR6400-D clears heavy carbon deposits from the DPF which will:

• Reduce regen frequency

• Restore performance

• Avoid engine damage by preventing a clogged DPF

In testing, AR6400-D increased miles between regens 46%.

Use AR6500 Diesel Treatment at every fill-up between AR6400-D applications to sustain a more complete combustion and reduce future carbon and soot build-up.

Definitely a nice improvement to my 2004 Duramax LLY

Ran a tank through a few months ago and it definitely improved boost response and overall smoothness.
I was getting occasional EGR codes and boost codes and haven't had any of those since either.
I'm usually skeptical of products like this but figured I'd give it a whirl and I am extremely pleased.
Just ran a second tank through and will likely do so every few months to keep my injectors and variable pitch turbo vanes clean and working properly.
I've owned this truck since new and it now has about 220,000 miles on it. I'm not a nut about checking fuel economy but it's definitely improved a bit as well.

Works good my diesel seems to start easier and runs smoother put some in my wife's equinox with the smaller diesel engine and less Regensburg and starts better when cold out

Old diesel

Old diesel as I’ve said numerous of times great product everything you put out I have tried and I’ve bought it numerous of times and will continue to do so I am quite happy with everything from the additive to the fuel to give me boost, to keep the fuel from gelling up, to get rid of section, and last but not least The additive I put in every 5000 miles I couldn’t be more happier and as I said before I look forward to your products when they come across my phone thanks again with respect Bob Brown
