AR6400-D Diesel Fuel System Cleaner

After running this through the first tank of fuel, I noticed a big difference in a smoother idle. It works great. I will definitely buy it again.

Great Product

I've been using Archoil products in my truck and farm tractor for over A year now this is a great product,I can tell a difference in mileage and regen in my Duramax,My tractor seemed to do really well this winter in the cold weather this year I recommend this product if feel it's worth the money for the fuel mileage and performance increase.
