RESTORE INJECTORS
• AR6400-D rapidly removes internal diesel injector deposits (IDIDs) and carbon build-up from injector tips
• AR6400-D ensures correct injector spray patterns, resulting in a more complete combustion and lower emissions for optimized performance

BOOST TURBO PERFORMANCE
• AR6400-D clears the turbine and variable vanes of soot and carbon, reducing turbo lag and restoring boost
• AR6400-D prevents the accumulation of carbon to reduce excess heat and wear, avoiding premature failure of the turbo

REDUCE DPF REGENS
• AR6400-D improves combustion to reduce carbon, soot and particulate exhaust emissions
• AR6400-D removes soot and heavy carbon deposits from the DPF which reduces regen frequency, restores lost performance and prevents engine damage from a clogged DPF
Improved fuel efficiency - AR6400-D improves fuel efficiency and economy by removing deposits and build-up in the fuel system, allowing for better fuel flow and combustion. This leads to lower fuel costs.
Enhanced engine performance - AR6400-D also restores engine power and performance, reducing engine noise and promoting smoother acceleration and idling.
Preventive maintenance - Regular use of AR6400-D can prevent future problems in the fuel system, such as clogged injectors and heavy carbon deposits in the DPF.
Cost-effective - Instead of waiting for fuel system components to fail, use AR6400-D to prevent premature failure and avoid expensive repairs. Use of AR6400-D extends the life of the engine.


Diesel from the pump typically contains little or no detergents which allows deposits to build and negatively affect the key fuel system components including injectors, turbos and DPFs. This leads to:
- Rough idling
- Poor fuel economy
- Black smoke
- Difficulty starting
- Engine misfires
- Increased emissions
AR6400-D contains a powerful dose of detergents for a one-tank treatment which rapidly cleans heavy deposits and restores power, performance and fuel economy. In testing, AR6400-D achieved a 7% improvement in MPG.
AR6400-D FAQs
AR6400-D is suitable for all diesel vehicles, including newer systems such as High Pressure Common Rail.
AR6400-D is a highly concentrated detergent package which should be used for a rapid, deep clean of the fuel system every 5,000 miles.
We recommend using AR6500 Diesel Treatment at every fill-up between uses of AR6400-D.
AR6500 Diesel Treatment boosts cetane, improves the lubricity of fuel and contains a maintenance dose of detergents to maximize fuel system performance at every fill-up.
