You Save:

Archoil AR6400-D Diesel Fuel System Cleaner utilizes the latest and most powerful fluid technology to deliver a cleaning service to the key fuel system components - injectors, DPFs, turbos and EGRs.

Experience restored performance, improved fuel economy and smoother idling as a result of cleaning the fuel system with AR6400-D.

AR6400-D does not cure Power Stroke HEUI injector problems (stiction). Please use AR9100 Friction Modifier instead.

Cleans Injectors

AR6400-D rapidly removes internal diesel injector deposits (IDID) and carbon build-up from injector tips in all diesel applications
AR6400-D ensures correct injector spray patterns, resulting in a more complete combustion and lower emissions for optimized performance
Cleaning carried out by using AR6400-D results in more power and efficiency and less frequent regens

Removes Turbo Deposits

AR6400-D removes carbon build-up from the turbo. Carbon build-up negatively affects turbo performance and life
Carbon and soot deposits restrict movement of the turbine and variable vanes inside the turbo, resulting in turbo lag and less boost
AR6400-D prevents the accumulation of carbon to reduce excess heat and wear and avoid premature failure of the turbo

Reduces DPF Deposits

AR6400-D improves combustion which reduces carbon, soot and particulate exhaust emissions
AR6400-D cleans soot and carbon deposits from the DPF
Reduction in carbon and soot build-up will reduce regenerations, prevent performance loss and potential engine damage from clogged DPFs

AR6400-D Data Sheet

AR6400 Frequently Asked Questions

How much diesel does one 12 oz AR6400-D bottle treat?

AR6400-D is formulated to treat up to 40 gallons of diesel with maximum results. AR6400-D is less effective when added to more than 40 gallons.

What's the difference between AR6400-D and AR6500?

A small amount of AR6500 Diesel Treatment is added to every tank of fuel to boost performance, ensure diesel quality and protect the fuel system from wear, deposit formation and corrosion. AR6400-D is designed to be added in large doses to remove existing deposits from your fuel system and engine. We recommend using AR6500 at every fill-up and using AR6400-D every 3,000 – 5,000 miles.

I am currently using AR6500 and my vehicle is running fine. Will there be any benefit to using AR6400-D?

Removing deposits which have built up over time from diesel engines will restore power and fuel economy which has been degraded by deposit formation. Using a fuel system and engine cleaner regularly will maintain optimum fuel economy and power. AR6500 Diesel Treatment is a maintenance product and will help keep your fuel system clean in between treatments. In order to remove heavy deposits the higher concentration of detergent offered by AR6400-D Diesel Fuel System Cleaner is necessary.

Can I use AR6400-D at the same time as AR6500?

Yes, you can use AR6400-D at the same time as AR6500

Can AR6400-D be used in my vehicle?

AR6400-D is suitable for all diesel vehicles, including newer systems such as High Pressure Common Rail.

Great stuff

I have a 2000 F350, 7.3 4x4 dually. Last year I dropped the fuel tank, cleaned it and the screens out. I also put in a new fuel filter after cleaning the bowl out. Amazing there wasn't much to clean out but I went and used the AR6400 and the AR9100 additives. The results were immediate for both less smoke, more power, and easier starts. This is the second time I've used the AR6400 cleaner, mainly as a preventative. Since the first time I used AR9100, I've also been using AR6500 fuel additive. The overall result is about a 1.8 mpg increase. With both the cost of repairing a diesel engine and the cost of diesel. These products are definitely worth it.

Archoil test

Lightly used ‘04 F250 109k I thought the truck ran great before Archoil but I wanted to give it a try. I used about a third of the engine additive and a third of the fuel additive. I noticed the truck had more power in normal city driving and seemed peppier out on the highway. I also noticed it would climb a steep hill in my neighborhood without downshifting. That rarely happened before great product!

Worked well

I saw an advertisement for this and thought I’d give it a try. Almost immediately I saw an improvement in performance. I will be using this as recommended by the manufacturer from now on.

Tried it and liked it.

I have to say it most definitely cleaned out the turbo on my 07 6.0. I could see the difference in the PSI right away. Knowing this, I would have to claim it also cleaned everything in the fuel system, including the injectors. Haven't been running it long enough to check mileage, but does seem to be more responsive.
The starting is better as well. The F-250 just turned 128,000 mi. I would recommend trying it, seems a low cost easy fix.

Great product
