Smooth running

This product has increased my fuel mileage. We had a recent cold snap down to 16 degrees. The fuel was still fluid and no gelling took place. My Ford runs smoother and it accelerates much better when I have this on board. Much better.

Significant increases in power and fuel economy!!!

Recently I just drove to Wyoming from Arizona and back on a hunting trip. I've made this trip several times in the past. The trip varies in elevation from 4500 up to 11,000 ft. On this trip I started using the Diesel All-In-One and I saw significant increases in power and fuel economy, especially in the higher elevations where my truck used to struggle a bit. Great product and works as advertised!!!
Bottom Line
Yes, I would recommend this to a friend.
