A rapid deep clean for the entire fuel system
AR6400-D's highly-concentrated detergent package contains proprietary chemistry that quickly removes deposits from the injectors and fuel system components.
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
Formulated to reduce DPF deposits
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 specifically formulated to reduce soot and heavy carbon deposits in 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.
AR6400-D reduces build-up from the turbo to:
- Reduce turbo lag
- Restore boost
- Reduce excess heat and wear
- Prevent premature failure

I used a bottle on my 2022 Ram and noticed a difference. Fuel mileage increased, less frequent regins and engine is more quiet. Will most definitely be using every 5k miles!

I have 5 - 7.3 trucks and have been using Archoil fuel treatment, injector cleaner and friction reducer products for 4 years now. Our engine performance has improved & have experienced almost zero breakdowns. Great products that deliver!

For months my truck would be throwing a NOX code even after I changed out both NOX sensors on my L5P. After running this fuel system cleaner in my truck, the check engine light has not thrown a code since. It’s probably been two months and no code.. I think it definitely cleaned my DPF and my truck’s running right now!

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.
J
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
J
I am using it in all of my construction equipment, my dump truck, excavator, skid loader, etc. I did a 10,000 mile test on my motorhome which is a super C freightliner Cascadia with an ISX 500 horse Cummins in the past it has done regions about every 6 to 800 miles and it would take about 30 minutes. Driving forward to complete the region Since running the arch oil cleaner threw it twice my last trip I just made 3800 miles before it did a region and the region last blasted 21 miles that should tell you everything you need to know

We've been running archoil products in our fleet for a while now. The results are amazing. The trucks start better, idle better, and run cooler. We haven't noticed any fuel economy gains, but that's not why we buy it. Our trucks just all around run smoother with these products.

I’ve used this product in the past on all my personal SEMA Featured Vehicle builds and it keeps all the necessary components lubricated as well a tad better mileage increase. Archoil Additives is the only true additive on the market that can add better lubricity, higher cetane, and mileage. Great product that I personally stand behind….wish I had them as another Sponsor on my builds. Wishing y’all the best in 2024 & all your future endeavors. 💯👊👍

Very helpful for my Silverado 6.6 L 2500 HD 😎👍🏼

This combination of additives has made all the difference in my 7.3 powerstrokes performance!

I believe your product worked as advertised, my mileage improved while pulling my 40 ft Toy hauler by 1.5 MPG and with out the trailer 2.7 MPG on a 1000 mile trip to Montana and back home to Washington.
C
I have a stock 2009 6.7 Cummins with 85k miles. for the past year my mpg has been decreasing little by little The best mpg was 12.5. I used one treatment of the AR 6400-D diesel fuel system cleaner. It took about two hundred miles before I noticed any change. Happy to inform you all that my mpg increased to 19.6. Very satisfied with this product!!

I have a 2016 Titan XD Cummins. I have put 5,000 miles on it sense I got it. Seamed like it REGEN a lot. I have used Secrets Extreme in it from first fill up until I saw these on sale. I don’t know if it is any better then the Secrets but it does not appear to be any worse and when it’s on sale it is a fair amount cheaper.

After two tanks of fuel with the Archoil cleaner, my diesel had noticeably better response, and over a 3mpg increase pulling a 42 ft 5th wheel. I am very pleased and would recommend Archoil to any diesel owner.
B
I have been using archoil since i had my 2007 f250 6.0. I now own a 2017 Nissan XD with the 5.0 Cummins. I immediately went to the internet and purchased archoil additives for my fuel and oil. The products are far super to any others.

I have a 2006 F-350. Just had the heads replaced. Thought I would try this. I'm looking for better fuel mileage. Went thru 1 tank of fuel and got no change. On the 2nd tank and see a little improvement. My truck is a crewcab long bed. I have done the EGR and Cat. delete. It has a K & N cold air intake. Any suggestions would be great.
D
Average fuel economy increased by 2 miles per gallon after adding to the system. Great stuff!
G
Great product motor is running a lot smoother, better throttle response and making more boost.
Will use again.
R
Seems to be helping, haven't ran a complete tank , 36 gal. and 1bottle of additive thru truck yet, so still testing for results.
G
I want to say it’s a coincidence, but almost immediately after putting this product in my tank my engine light came on. Found that it was the diesel exhaust fluid heater that had failed. Again, I wanna call this a coincidence. Other than that I have not noticed any difference in performance
M
Outstanding product it work's better then they advertise on their video. My Dodge Ram 2500 4X4 Cummings Turbo Diesel has 140,000 plus miles and I've use 2 bottles of the Archoil Cleaner her fuel mileage went up 2mpg and she Runs Smoother and Faster Acceleration. Great Job Archoil
A
Love it !!!!! I can tell a big different in my 2005 F250 6.0 Throttle Response A+,,no more rough idling A +,, power increase A+++. Will order again
