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 and corrosion. 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. Archoil AR6300 Winter Diesel Treatment does offer anti-gel protection.

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.

Very happy

Received my AR6200 treatment, packaging is was good, fast shipping. I started with a power dose of AR6200 in my Suburban. It seemed to work well after adding it runs a little smoother. I then put some in my lawn tractor. The tractor always surges at idle and while cutting. After using the AR6200 and about an hour run time , the surging has stopped !!! It now idles smooth and sounds better while cutting. All in all I’m happy with this product and would buy again and recommend to friends.

Not snake oil

My dirtbikes, mowers and pressure washer actually start up like they should. 10 years struggling with starts and dont have issues anymore. Also use in my truck 25 ml each fillup. Better idle hands down. Not noticing much else there but also not paying attention since I seen it work so well on the small stuff. The second I found out this stuff was originally invented by Bell Labs (AT&T) for backup generators not starting, I had confidence in it. Surprised we can buy it honestly.





Essential for winter

Archoil is great as a gas additive in winter to keep the effects of ethanol at bay. It's also essential for small engines if they're not used regularly. The fuel stays fresh. I add it to my 2 cycle mix for my 28 year old snowblower and it starts on the first pull!
