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

First time I have ever been blown away about the performance of an additive. This stuff is amazing. Cummins runs stronger, quieter and even the exhaust note is changed. I would recommend this stuff to anyone with a diesel.

so far it doing good

When the O2 sensors get dirty, my truck stutters run fuel treatment a few times good to go love the shit

I run Archoil in my Duramax Denali and it had increased fuel mileage and overall the truck just runs so much better. I used to regen every 500 miles or so, now it’s over 1000 miles between regens… I’m a lifer, I’ll use Archoil as long as I have a diesel
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.
