Archoil AR6500 Diesel Treatment

Archoil formulated the AR6500 Diesel Treatment to address issues associated with modern diesel fuels. AR6500 incorporates the most powerful and advanced diesel additive chemistry that is currently available. Only 100% active ingredients are used with no fillers, offering greater value per fill-up.


Archoil engineered the AR6500's detergents and lubricants to clean, lubricate and protect your fuel system, including injectors, pumps, lines and tanks in all fuel systems, including the latest high-pressure common-rail injection fuel systems.


AR6500 also incorporates Archoil's proven combustion modifier technology and a substantial cetane boost to increase power and response and reduce soot and carbon build-up in turbos, DPF and EGR components.



Features & Benefits


• Increases Power and Response

• Improves MPG 6-10%

• Reduces DPF Regen Frequency

• Dissolves Sludge and Stabilizes Fuel

• Improves Lubricity and Extends Component Life

• Maintains and Protects Injectors and Fuel System

• Disperses Water and Protects Against Corrosion

• Boosts Cetane up to 8 points


A More Complete Fuel Burn

AR6500 will ensure the injector spray patterns are correct and provide an improved fuel burn boosts fuel efficiency, power and response. Proper combustion also means less soot/carbon emissions produced, which keeps the engine, turbo, and emissions systems (EGR, DPF etc.) free from soot deposits.


Keeps Diesel Particulate Filter Clean

Due to reduced soot emissions, vehicles equipped with a Diesel Particulate Filter (DPF) will benefit from reduced frequency and length of DPF regeneration, which results in significant fuel efficiency gains. When the DPF captures less soot, much less fuel is needed to burn it off, and there is less exhaust backpressure which reduces engine efficiency.


Protects Fuel System

Detergents will keep your fuel system clean, preventing the formation of power/economy robbing deposits. A lubricity improver will prevent wear in all fuel systems, including the most modern high-pressure diesel fuel systems. AR6500 will also combat corrosion as well as disperse water and keep the fuel filters clean.


Fuel Stability and System Protection

AR6500 will maintain fuel stability by preventing fuel from degrading and forming sludge and varnish, which does not burn readily and can plug the fuel filters and injectors if left untreated. A powerful dispersant will dissolve the sludge and varnish allowing it to pass through your fuel system and burn completely.


Cetane Number

Fuels having lower cetane ratings lead to poor fuel economy, less power and higher emissions. The common cetane rating at the pump is between 40-45, and the cetane your truck typically needs is between 47-50. Raising the cetane rating with AR6500, fuel mileage, horsepower, and throttle response improve while emissions reduce.



Treat Rate

  • One 16.7 oz bottle treats 625 litres (165 gallons) of diesel

  • One 33 oz bottle treats 1,250 litres (330 gallons) of diesel

  • EVERYDAY: 30 ml (1 oz) per 38 litres (10 gallons) of diesel

  • POWER BOOST: 60 ml (2 oz) per 38 litres (10 gallons) of diesel

  • Add AR6500 to the fuel tank at the required dosage and then add fuel. Use at every fill-up.
