Standard: 1 oz (30ml) of AR6500 per 10 gallons of diesel.

Power Boost: 2 oz (60ml) per 10 gallons of diesel. For best results use Power Boost dose in first tank of fuel.

AR6500 is suitable for use in all diesel vehicles, including newer systems such as High Pressure Common Rail.

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

Best choice for my rig

As a delivery route driver averaging 150-180 miles a day, 60% highway/40% in town, DEF use and regens were adding to my operating costs. With Archoil, I see less regens, use less DEF, gained about 1.5 mpg overall fuel average. This is an investment in my truck(2022 Ram2500) and not a cost.

product delivers on promises

since using this product ,I can feel the additional responsiveness on the throttle. and I can even hear the crisp clean whir of the Turbo again. tells me the additive is doing its job and delivering on the promises made, the truck has a great responsiveness to it, under acceleration.

AR6500

Have run less than one tank through my 2020 F250 and have seen approximately 2 mpg increase so far.

Just started using so not a lot of info to share..

I just started using the product as I work through the last bits of HotShots product. With all the info from other I feel good about the outcome when I do use it more.. Currently we are not moving a lot and have a car we use more often but that will change soon as we head back on the road. I will update then then..

ONE thing I think would be very helpful for many would be the ability to buy the product in Gallon containers we can use to refill the measure bottle they now sell.. Was able to do that with HS EDT and it was so nice to not have to worry about product for a WHILE..

something to think about Archoil..

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.
