AR6200 FAQs

A small amount of AR6200 Fuel Treatment 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.

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.

No, AR6200 does not offer any anti-gel protection. Use AR6300 Winter Diesel Treatment for anti-gel protection.

Great for Classic Cars

I have been using Archoil fuel additive in my 1971 TR6 for 3-4 years now. My car runs great, spark plugs are not fouled anymore. I use it at every fill up.

Thumbs Up

I use this in my classic cars and all my engines.
This with the other AR products have helped me save from rebuilding my old engines and transmissions. My farmer friends use it in their tractors and trucks. It makes the engines and transmissions run cooler and quieter. Better gas mileage is also good. Thanks Archoil.

Not snake oil, I am happy to say

I figured I would try this additive to quiet my ticking injectors on my 2019 Titan. They are now silent. Much to my surprise my fuel mileage average, in town, went from 15.5 MPG to 17.3 MPG. Nothing has changed in my driving habits. Verified through 3 tanks of fuel. I am happy to report this.

Amazing results

I have a couple vehicles that are not driven much. I've tried several fuel treatments to restore volatility. AR6200 did an excellent job. My wife's older Honda has a minor hesitation. AR6200 completely removed the hesitation and the car runs very smoothly. Highly recommended.
