  • Lubricates and protects the fuel system
  • Reduces maintenance and extends component life
  • Increases fuel economy
  • Boosts cetane up to 8 points

Standard: 1 oz (30ml) of AR6500 Diesel Treatment 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.

On average, AR6500 users experience an MPG increase of up to 10%, representing a saving of up to $114 in fuel costs per 40.6 oz bottle.*

In testing, AR6500 increased MPG by 11.1% in a 2011 Ford F-350.

*Based on average U.S. fuel prices, March 2022

The common cetane rating of diesel at the pump is between 40-45 and the cetane your vehicle typically needs is between 47-50. Improving the cetane rating of fuel will increase MPG, power and response while reducing emissions.

IMPROVE DIESEL QUALITY

Maximize Power, Performance and MPG

AR6500 cleans, lubricates and protects your fuel system including injectors, pumps, lines and tank in all systems including the latest high pressure common-rail systems.

AR6500 also incorporates Archoil's proven combustion modifier technology and a strong cetane boost to increase power and response at every fill-up.

CLEAN INJECTOR DEPOSITS

• Remove carbon deposits to ensure correct injector spray pattern

• Restore lost horsepower and fuel economy

• Prevent further carbon build-up

REMOVE CARBON FROM THE TURBO

• Remove carbon from fuel system components including the turbo, DPF and EGR

• Prevent turbo lag, restoring boost and reducing DPF regenerations

Use of AR6500 improves the poor quality of diesel at the pump, cleans and maintains fuel system components and revives engine performance. In testing, AR6500 increased MPG by 11.1%

Improve Fuel Lubricity

In independent ASTM wear scar testing, base diesel fuel produced a scar width of 614.5 microns. The same fuel treated with AR6500 produced a scar width of 347.5 microns - increasing lubricity 45%. Improving lubricity extends component life and prevents premature failure.

It Works !

Improved the fuel economy in my 2005 GMC Sierra 3500 Duramax. I towed my Excursion on a flatbed from Michigan to Georgia. My first tank of fuel averaged 11.1 mpg with no Archoil, straight diesel fuel. . The second and third tanks were treated with Archoil 6500 Diesel (powerboost dose) and fuel averaged 13.8 mpg. The stuff works and it will be the only fuel treatment I will use. It pays for itself!

Improved milage

I have only used this in my TDI so far. I always use treatments, and was using one that was highly rated. This still improved milage by 12%. Can't wait to see what it does I'm my Power stroke.
