AR6400-D Diesel Fuel System Cleaner

One 12 oz bottle of AR6400-D treats 40 gallons of diesel fuel.

Add directly to the fuel tank before filling up.

Use every 5,000 miles OR use once for a deep clean and then follow up with AR6500 every fill-up for continuous cleaning.

AR6500 Diesel Treatment

Standard: 1 oz (30ml) of AR6500 per 10 gallons of diesel.

Power Boost: 2 oz (60ml) per 10 gallons of diesel.

Add to the fuel tank before every fill-up. Wait until the next fill-up if using AR6400-D.

AR6400-D and AR6500 are suitable for use in all diesel vehicles, including newer systems such as High Pressure Common Rail.

Today’s diesel fuel isn’t what it used to be. Due to government regulation for Ultra-Low Sulfur Diesel (ULSD), modern diesel fuel has been stripped of essential components including detergents and lubricity. Cetane levels are also often too low, as many US states mandate a minimum rating that doesn't meet most diesel engines' needs.

Without these crucial elements, deposits such as carbon, metal carboxylates, and zinc accumulate within your fuel system, turbo, and DPF. If left unchecked, this leads to a range of performance issues you have likely felt, such as turbo lag, increased DPF regens, lower MPG, poor throttle response, and overall power loss.

Unlike other diesel fuel additives, we don’t just treat the symptoms of poor fuel quality – we eliminate the root cause. Our products have been engineered with a powerful, proprietary formula that cleans your entire fuel system, including hard-to-reach components like the turbo and DPF.

AR6400-D Diesel Fuel System Cleaner targets the symptoms caused by poor diesel quality: the build-up of harmful deposits such as carbon, zinc, and metal carboxylates. Its powerful detergent package deep cleans your injectors, turbo, and DPF to eliminate the blockages that steal your engine’s power and efficiency.

AR6500 Diesel Treatment then targets the root cause of the problem by improving the quality of your diesel fuel. It boosts cetane levels, enhances lubricity, and provides ongoing maintenance with every tank, ensuring that your engine operates at peak performance, even when using poor quality modern diesel fuel.

Together, these products form the Diesel Fuel System Kit, a fully comprehensive approach to restoring diesel performance and maximizing power. While other diesel additives may boost cetane a little or provide a small amount of cleaning, Archoil addresses the entire issue, ensuring you’re treating not just the symptoms, but the root cause as well.  

The quality of our additives is backed by thousands of 5-star reviews and our no-questions-asked 100% Money Back Guarantee. Archoil is the ONLY solution you need to restore performance and protect your engine.

Before Injector Restoration After Injector Restoration

Restore & Maintain Injector Performance

  • Improve combustion
  • Correct spray patterns
  • Reduce carbon deposits
  • Enhance fuel economy

Most diesel fuel lacks the detergents and cetane needed to prevent carbon build-up, 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.

Before Turbo Restoration After Turbo Restoration

Remove Carbon & Reduce Turbo Lag

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

Unlike other treatments, the chemistry in AR6400-D removes build-up from the turbo.

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

Before DPF Restoration After DPF Restoration

Clean the DPF & Reduce Regens

  • Restore MPG & performance
  • Protect against engine damage
  • Prevent costly DPF replacement

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 survive the combustion process, removing soot and heavy carbon deposits from the DPF.

Boost Cetane & Increase MPG
  • Improve combustion efficiency
  • Increase power and response
  • Extend component life

Most diesel engines require fuel with a cetane number (CN) of 48-50 to operate efficiently but fuel in the US typically has a CN of 40-45. A low CN results in poor combustion, causing soot deposits and carbon build-up in key fuel system components.

AR6500's cetane boost of up to 8 points is greater than other products on the market and enables optimized engine performance.

Improve Lubricity & Engine Life
  • Protect engine components
  • Reduce maintenance costs
  • Improve engine reliability

Lack of lubrication in diesel fuel is a major issue for both older and newer vehicles, leading to excessive wear, costly repairs and potential failure of components including injectors and pumps.

AR6500 has been independently tested to reduce wear by 43%, reducing friction and wear on the fuel system.

Keep Injectors, Turbo & DPF Clean
  • Restores injector spray patterns
  • Protects turbo performance
  • Reduces DPF regeneration frequency

AR6500 contains a maintenance dose of AR6400-D's detergent package for continuous cleaning of the entire fuel system.

As AR6500 is added to the tank at every fill-up, your engine will always have the detergents it needs to break down existing build-ups while preventing the formation of harmful new deposits.

Gotta give it a shot 8d you see your new diesel loosing power and fuel mileage

Been getting bad fuel lately lost MPG AND POWER tried the AR6400D and wow what an improvement on a fresh tank of fuel my mpg went back to 30mpg hwy / 28mpg in the city back to like new with only a 2yr old truck. I use the AR6500 FUEL TREATMENT AT every fill up. Awesome product

Works good

My eco diesel was starting to go through 4 regens every tank of fuel so I decided to give it a try and now it's back to one regen per tank of diesel (about 1 per 600 miles)
