Unlike other everyday treatments, AR6500 cleans the entire fuel system and post-combustion system (turbo, DPF), providing unparalleled protection for your engine. Additionally, AR6500 offers a stronger cetane boost and superior lubricity improvement compared to other products on the market, ensuring enhanced performance and maximized fuel economy.
In the US, most diesel engines require a cetane number (CN) between 40 and 55, but most diesel fuel has a CN of around 40 to 45. Low CN results in poor combustion, causing soot deposits and carbon build-up in key fuel system components.
AR6500 Diesel Treatment offers multiple benefits by boosting cetane by up to 8 points. This results in:
- Improved combustion efficiency
- Enhanced fuel economy
- Reduced regens
- Increased power and performance
- Extended component life
Most other products on the market provide a more modest cetane boost, insufficient to meet manufacturer recommendations.
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 Diesel Treatment has been independently tested (ASTM D6079) to increase lubricity by 43% and reduce wear scar width from 615 microns to 348 microns, well below the Engine Manufacturer's Association's recommended maximum of 460 microns. This results in:
- Protected engine components
- Reduced maintenance costs
- Improved engine reliability
- Extended component lifespan
AR6500 contains highly concentrated detergents which remove internal diesel injector deposits (IDIDs) and carbon build-up from injector tips.
AR6500 cleans injectors to:
- Improve fuel atomization
- Produce a more complete combustion
- Correct spray patterns
- Reduce carbon deposits
- Enhance fuel economy
Over time, carbon builds up in the Diesel Particulate Filter (DPF) and leads to reduced engine performance, reduced fuel economy, and potential engine damage. Frequent regeneration cycles and warning lights indicate ongoing issues, often resulting in costly repairs.
Cleaning a DPF manually is not possible on many vehicles and replacement typically ranges from $2,000 up to $10,000. Unlike other additives, AR6500 utilizes proprietary chemistry to remove carbon build-up from the DPF. This results in:
- Reduced regeneration frequency
- Restored MPG & performance
- Prevention of engine damage due to a clogged DPF
A dirty turbo restricts airflow, reducing engine efficiency and power. This leads to increased fuel consumption and turbo lag. Carbon deposits can also cause overheating and potential failure, resulting in costly repairs.
Certain elements of Archoil's proprietary chemistry blend survive the combustion process and utilize heat from the exhaust to remove carbon build-up from post-combustion system components including the turbo. This results in:
- Reduced turbo lag and restored boost
- Minimized wear and damage
- Restored optimal temperature
- Improved airflow efficiency
AR6500 FAQs
AR6500 improves lubricity in fuel, cleans and maintains the fuel system and adds cetane for a boost that can be felt at every fill-up. AR6400-D is a highly concentrated one-tank fuel system cleaner to be used every 5,000 miles for rapid cleaning of heavy carbon build-up.
AR6500 is suitable for all diesel vehicles, including newer systems such as High Pressure Common Rail.
AR6500 will remain stable indefinitely if kept away from sources of heat and sunlight.
No, AR6300 Winter Diesel Treatment is the product you need for cold weather. AR6300 contains all the benefits of AR6500 plus anti-gel protection up to -44ºF.
