4d - AR6400-D Diesel Additive Description


AR6400-D is an advanced fuel additive blended from the latest high-strength polyetheramines and BIPSA/PIBSI detergents that quickly and safely remove gum, varnish and carbon deposits from the fuel system and engine. Advanced combustion modification chemistry then maximizes combustion performance to help remove post combustion hydrocarbon build-up whilst rapidly reducing harmful exhaust emissions.

AR6400-D quickly restores lost engine performance and fuel economy in addition to unique properties that help protect surfaces from further deposit build-up. Molecule by molecule deposits are safely removed from intake valves and piston tops thus improving combustion efficiency and reducing the propensity for pre-ignition.

AR6400-D is suitable for all 4-cycle gasoline engines, including ethanol blended fuels and biofuels. AR6400 is not suitable for 2-cycle engines.

The first family of dispersant/detergents were amines with a polyisobutylene (PIB) tail. The PIB tail gave good solubility and the amine group provided surface activity that lifted deposits from the metal surface. However the PIB tail, as a polymer, gave the undesirable effect of stickiness so the PIB amine had to be combined with a fluidizer to ensure that it flowed through the combustion region of the engine and did not build up any residues. The fluidizer was typically a polyolefin epoxide.

The next generation of chemistries combined the fluidizer with the polymeric amine. These are called polyetheramines or PEA. Polyetheramines do not require the addition of a fluidizer and the oxygen content provides enhanced surface activity.

PIB amines are still widely used in gasoline and perform well. However, PEA’s offer improved combustion chamber cleaning efficiency but is considerably more expensive.

There is an abundance of supply of PIB amines unlike with PEA; hence the treatment cost is significantly higher. Therefore, PEA’s are not widely found in low cost cleaners or are found in reduced quantities. AR6400 contains the highest safe amount of PEA and accompanying chemistry to safely move deposits.


Add the correct amount of AR6400 to the fuel tank first and then fill up with fuel immediately afterwards.
Treatment ratio is 1:100 > 1:200. A single 16oz bottle will treat 30 gallons of fuel depending upon carbon buildup.
Use every 5000 miles or use once and follow up regularly with Archoil AR6200 Fuel Modification Complex
