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.

The perfect fuel additive

2022 Ram 2500, 6.4L Hemi. Started using AR6200 and within 2 fill-ups am seeing a solid 2.5 mpg difference. Very satisfied.

Tried some for my gas engine

The diesel additive works so well I wanted to try the gas version. I wish they sold it in the same size as the diesel additive.

Great Product

Mileage increased from 15.7mpg to 18.6 mpg and the engine ran smoother.

Motorhome protection

I previously purchased and used the diesel kit for my ford 6 Liter. I also used the oil change additive. Thankfully this made huge improvements in my truck’s performance “mostly turbo”. Now i add archoil to every tank.
My motor home v10 runs great but I’m using the gas treatment mostly for the onan generator, since it sits for prolonged periods.
