AR6400 is incredible! My 2022 Duramax acceleration increased dramatically when I added. I’ll be using every 5000 miles as directed.

AR6400-D Diesel Fuel System Cleaner

I usually only use the truck for towing my trailers so the fuel economy is impacted on a regular basis. After using the cleaner I didn't notice any appreciable increase in fuel economy but I did notice better throttle response and performance. When not towing I did notice a slight increase in fuel economy but much better throttle response and performance.
