Use AR6400-D Diesel Fuel System Cleaner and AR6500 Diesel Treatment to protect your engine, restore your diesel fuel system and boost performance. We recommend using AR6400-D every 5,000 miles and AR6500 in every tank of fuel.

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 has changed due to government regulations for Ultra-Low Sulfur Diesel (ULSD), stripping it of essential components including detergents and lubricity. Cetane levels are often too low, as many states mandate a minimum that doesn't meet most engines' needs.

Without these elements, deposits such as carbon, metal carboxylates, and zinc build up in your fuel system, turbo, and DPF. This can lead to issues like turbo lag, more frequent DPF regens, lower MPG, poor throttle response, and power loss.

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

AR6400-D Diesel Fuel System Cleaner targets harmful deposits like carbon, zinc, and metal carboxylates, by deep cleaning the injectors, turbo, and DPF to restore power and efficiency.

AR6500 Diesel Treatment improves fuel quality by boosting cetane, enhancing lubricity, and continuously cleaning the fuel system for peak performance, even with poor-quality diesel.

Together, these products form the Diesel Fuel System Kit, tackling both symptoms and causes of poor fuel quality. With thousands of 5-star reviews and a 100% Money Back Guarantee, Archoil is the only solution you need to protect your engine.

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.

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.

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.
