    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.

    AR6400-D is suitable for use in all diesel vehicles.

    A rapid deep clean for the entire fuel system

    AR6400-D's highly-concentrated detergent package contains proprietary chemistry that quickly removes carbon deposits from the injectors and, unlike other diesel additives, the DPF and turbo.

    By targeting these critical components, AR6400-D will:

    • Restore engine performance
    • Boost fuel efficiency
    • Reduce wear and tear
    • Prevent costly repairs
    Bring your diesel injectors back to life

    Most diesel fuel lacks the detergents and cetane needed to prevent carbon buildup, leading to poor combustion, reduced power, and potential injector failure.

    AR6400-D contains a strong dose of highly concentrated detergents which quickly remove internal diesel injector deposits (IDIDs) and heavy carbon build-up from injector tips, in order to:

    • Improve combustion
    • Correct spray patterns
    • Reduce carbon deposits
    • Enhance fuel economy
    The only treatment to clean the DPF

    Over time, carbon builds up in the Diesel Particulate Filter (DPF) which results in more frequent regenerations, poor engine performance and potential failure. DPF replacement costs typically range from $2,000 up to $10,000.

    AR6400-D is the only diesel fuel system cleaner specifically formulated to remove soot and heavy carbon deposits from the DPF. Use AR6400-D to:

    • Reduce regeneration frequency
    • Restore MPG & performance
    • Prevent engine damage
    Restore turbo performance

    Carbon build-up in diesel turbos significantly impairs performance by restricting airflow and increasing exhaust backpressure and leads to turbo lag, reduced fuel efficiency and potential engine failure. In VGTs, carbon deposits cause the vanes to stick, resulting in inconsistent power delivery.

    Unlike other treatments, AR6400-D removes build-up from the turbo to:

    • Reduce turbo lag
    • Restore boost
    • Reduce excess heat and wear
    • Prevent premature failure

    Regeneration almost gone!

    I started with Archoil 6 months ago after constant regeneration was happening. Since then I haven’t gotten 1 notification. These products are lifesavers!

    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.
