The only treatment to clean, restore and boost the entire fuel system
AR6500 upgrades the quality of diesel fuel at every fill-up by providing a strong cetane boost, enhanced lubricity and a powerful detergent package.
AR6500 maintains clean injectors, and unlike other diesel additives, keeps your turbo and DPF free from carbon build-up.
Add at every fill-up to:
- Improve combustion efficiency
- Increase fuel economy
- Reduce DPF regeneration
- Protect the fuel system
- Extend component life

Boost cetane to increase power and response
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, helping to:
- Improve combustion efficiency
- Enhance fuel economy
- Increase power and performance
- Extend component life
Improve lubricity to extend fuel system life
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 in order to:
- Protect engine components
- Reduce maintenance costs
- Improve engine reliability
- Extend component lifespan
Clean injectors and restore spray patterns
Over time, carbon deposits form on diesel injectors. Dirty injectors can’t spray fuel into the engine correctly, leading to incomplete combustion and wasted fuel.
AR6500 not only keeps injectors clean but by increasing cetane and improving combustion, helps prevent further build-up of deposits.
- Improve fuel atomization
- Reduce carbon deposits
- Enhance fuel economy
The only treatment to clean the DPF and reduce regens
Carbon build-up in the Diesel Particulate Filter (DPF) reduces engine performance, lowers fuel economy, and leads to increased regeneration frequency.
AR6500 utilizes proprietary chemistry to remove carbon build-up from the DPF, in order to:
- Reduce regeneration frequency
- Restore MPG & performance
- Prevent DPF-related engine damage
- Increase DPF lifespan
Prevent turbo failure and restore boost
A dirty turbo restricts airflow, leading to reduced engine efficiency, increased fuel consumption, and turbo lag. Carbon deposits can also cause overheating and potential failure, resulting in costly repairs.
AR6500’s proprietary chemistry survives combustion and uses exhaust heat to remove carbon build-up from the turbo, helping to:
- Reduce turbo lag
- Restore boost
- Minimize wear and damage
- Restore optimal temperature
- Improve airflow efficiency

Mileage increase 2-3 mpg. Hopefully lubricating CP4.

I’m on my 4th tank of diesel. I haven’t noticed any increase in mileage, however I feel good about using the product. I’m going to try the fuel additive and see if this improves my mileage. I like the fact that it provides lubrication and keeps soot down in injectors.

Haven’t driven my 6.0 much in the past year. Put maybe 600 miles on it. I’m usually out of town working. Recently I started driving it for my daily again. Injectors would haze on every cold start. Decided to use the archoil diesel treatment since I run the oil additive already. Injectors completely stopped hazing on cold starts. Quality oil and fuel additives. Worth the money.

This is an honest, unscripted review of Archoil's AR6500 diesel fule treatment.
Have a 2019 Powerstoke since new. With known problematic CP4 pump issues (reportedly impacts 7% of 6.7 engines), was using Costco Top Tier fuel supplemented with Power Source additive at every fill up. Mileage and regens required a jug of DEF every four months or so. I average 15,000 miles driving with a combination of in-town / highway driving. This includes pulling 13.5Klb travel trailer.
On a whim (in addition to be recommended by my close friend who is also the local Ford Dealership Service Manager) I tried Archoil's AR6500 fuel treatment about four months ago.
Since then, I noticed an increase of fuel economy. I don't have hard numbers but repeated trips into town (we live in the country) reflects in the fuel gauge barely moving. I also drive like an older person (since I am) but know it is more than the 22mpg average I was getting with Power Source.
I also noticed my regens are more infrequent. My DEF tank level gauge hasn't budged since I filled it up since New Years. I also noticed while getting mail, my radio seemed louder when I parked my idling truck. Normally, I would hear my diesel idling (with Power Source) competing with my favorite rock tunes. However not with Archoil AR6500. The engine is actually idling quieter. Pretty amazing stuff!
So there you have it.
