Free AR6400-D Diesel Fuel System Cleaner

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%.

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.

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.

To maximize performance, increase MPG and improve fuel quality, Archoil's AR6500 Diesel Treatment should be used at fill-ups between treatments of AR6400-D.

AR6500 boosts cetane for a cleaner fuel burn, raises fuel lubricity above the level recommended by the Engine Manufacturers' Association (test results pictured) and contains a maintenance dose of detergents to keep the fuel system clean and extend component life.

The Diesel Fuel System Kit includes AR6400-D and AR6500 (40 oz - treats 400 gallons).
