Archoil's AR6200 Fuel Treatment brings more power and response at every fill-up while protecting your fuel system and improving fuel efficiency.

AR6200 is suitable for use in both diesel and gasoline.

AR6200 is highly concentrated - a 16.9oz bottle treats 500 gallons of fuel.

Upgrade Your Fuel

  • Combustion Modifier: A more complete combustion improves efficiency, power and response
  • Lubricant: Protects fuel pump and injectors from wear and failure, lubricates upper cylinder
  • Dispersant/Detergent: Helps dissolve sludge and other fuel system deposits. Restores degraded fuel
  • Stabilizer: Enables extended fuel storage
  • Corrosion Inhibitor: Protects the fuel system from corrosion
  • Biocide: Eliminates microbial growth (algae, bacteria)
  • Demulsifier: Improves water separator effectiveness

In addition to the universal benefits listed above, AR6200 users will also notice further diesel or gasoline specific improvements.

Diesel Benefits

AR6200 addresses issues associated with poor quality diesel, including the accumulation of performance-robbing soot, to restore and maintain vehicle performance. AR6200 increases cetane and many users will also notice an increase in fuel economy (MPG). The DPF will be kept clean, resulting in less frequent regens. Turbo and emissions systems will also be kept free from excessive soot.

Gasoline Benefits

AR6200 is also beneficial in gasoline vehicles and small equipment. Adding the fuel treatment prevents ethanol degradation/corrosion, combats knocking/pinging and improves gasoline's resistance to pre-ignition. AR6200 is also great for classic vehicles which were designed to run on leaded fuel and prevents issues when storing seasonal equipment.

How it Works

More complete fuel burn

AR6200 will ensure a more complete fuel burn which improves fuel efficiency, power and response. A more complete fuel burn also means less soot/carbon emissions are produced which keeps the engine, turbo, and emissions systems (EGR, DPF, catalytic converter 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 big 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 and a lubricity improver will prevent wear in all fuel systems including the most modern high pressure fuel systems. AR6200 will also combat corrosion and microbial (bacteria, algae) growth in the fuel tank as well as improve the effectiveness of water separators/filters equipped on diesel vehicles.

Fuel stability and system protection

AR6200 will maintain fuel stability, permitting long term fuel storage by preventing fuel from degrading and forming sludge and varnish which does not burn readily and can plug fuel filters and injectors if left untreated. A powerful dispersant will dissolve sludge and varnish allowing it to pass through your fuel system and burn completely.

AR6200 Frequently Asked Questions

What's the difference between AR6200 and AR6400 (D or G)?

A small amount of AR6200 Fuel Modification Complex is added to every tank of fuel to boost performance, ensure fuel quality and protect the fuel system from wear, deposit formation, corrosion and microbial growth. AR6400 (D or G) is designed to be added in large doses to remove existing deposits from your fuel system and engine. For example, a 16.9 oz bottle of AR6200 treats up to 500 gallons of fuel and a 16 oz bottle of AR6400 (D or G) treats up to 25 gallons of fuel.

Does AR6200 help prevent issues with ethanol?

AR6200 will help to prevent some issues with ethanol fuels including issues with deposit formation and fuel stability. AR6200 will also help prevent microbial growth and corrosion which can occur in the presence of ethanol.

Does AR6200 offer cold weather anti-gel protection?

No AR6200 does not offer any anti-gel protection, but you can use AR6200 at the same time as an anti-gel additive if you would like.

Is AR6200 compatible with other additives?

To check if AR6200 is compatible with another fuel additive, locate the SDS sheet and look in section 10 'Stability and Reactivity' for incompatible substances. AR6200 is incompatible with strong oxidizing agents and acids. If the product in question is incompatible with alkaline materials according to the 'Stability and Reactivity' section on the SDS sheet then it will not be compatible with AR6200 which is a strong base. You can also email for review. Most fuel additives reviewed are compatible with AR6200.

What is the shelf life of AR6200?

AR6200 will be stable indefinitely if kept away from sources of heat and sunlight.

Great Product

Used this in my 6.7 from day 1. Small price to pay for piece of mind on the fueling system components and a cleaner running engine.

Small miracle.

I daily drive a 650hp 2005 F250 6.0 and use Archoil in the fuel and oil for about 6 months now. Completely eliminated stiction in about 3k miles, went from 32-35 mpg on the freeway to 48-48.5! Don’t notice a power boost when I double dose but it definetly cuts down on soot in those everyday situations like taking off from a dead stop with a cop behind you lol I do think it is over priced but I’d rather spend the $50 or whatever on the juice instead of 3k on injectors. I would consider Archoil regular maintenance if you daily your 6.0. I wish they had application specific oil additive for everything even though I do put the friction modifier in everything except the tranny. Stay away from the tube grease tho it separates and leaks rite out of your gun.. sucks when you paid like $80 for a tube haha they saw me coming that’s forsure.

I believe

I have always believed that adding a little something to motor oil/gas tank was beneficial to performance and long life. I began using ARCHOIL products about 3 years ago. I needed some engine work (gaskets replaced) last fall and the mechanic reported that the pistons were clean as new (224,000 miles) and continue to do whatever I have been doing - and I will continue using ARCHOIL products!


Ran the double dose through 2 tanks. My truck only has 19000 miles, just want to make sure the pump stays lubed and exhaust stays clean. So far so good. Will review after use the whole bottle.


Wished I had thought about Black Friday-Monday specials to reap the (any) savings.
