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.

Good overall fuel additive

Good all around fuel additive for general use. Engine runs smoother and quieter immediately upon use and I like to use as a maintenance additive.

Muy bueno!

Excelente producto, lo uso en mi Lobo ecoboost desde hace dos años, he observado através de este tiempo que hay menos carbón en el escape y no "cascabelea". Lo seguiré usando.

Archoil guys: It really needs to be available again in a P1 kit.

archoil Fuel Treatment for 7.3 is The Best

Used archoil fuel treatment and I am amazed at the performance and fuel mileage on all my 7.3 engines. Bought more for my family that all have 7.3 Powerstrokes from 1995 through 2003.

Good stuff!

I've been using the AR6200 with nearly every tankful of gas for about 15 months now in an '04 Suburban with a 5.3 Vortec. We bought the car about 6 years ago with 100,000 on it and it ran very well at that time. Then it slowly seemed to lose power, acceleration, etc. The car now has over 200,000 miles on it, and with this recent fuel treatment it runs better than it did when we bought it! The acceleration when merging onto a highway, etc, still surprises me. I used to the think the engine was underpowered for this heavy car - and with poor performance it was. Not the case anymore, that engine just needs to be allowed to run well! I also installed the 9100 friction modifier with an oil change 15 months ago, but it was only with one oil change as I used up this product in some other machines. I don't know whether it's the fuel conditioner or the friction modifier or a combination of both, but this engine just runs great - at 200,000 miles!
