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

We have been using this product for 2 years. Our Diesel Technician indicates the diesel particle filter on the engine is as clean as possible. We will continue to purchase/use this product.

I have a 2024 Duramax with 13,000 miles on it. I started using archoil products at 6,000 miles haven’t noticed any difference yet. Preventative maintenance to keep it burning clean.

I've used it in a few tanks of fuel, one right after the next. Mixed per instructions. 2 different trucks. 2015 Ram 2500 and a 2016 Ram 3500 DRW dump. I have not noticed much of any difference in fuel economy. The 2015 still gets 22mpg and my 2016 one ton dump still gets 9mpg. The 15's turbo seems a little more responsive so it must be cleaning things internally. The 16 has used less DEF. I will keep running it to see if there is more improvement.
P
Cannot really give you a true review. only ran one tank full of fuel to my truck.
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.
