We received a letter from Jim Laughland, who is the supervisor at American Aggregates’ underground limestone mine in Indianapolis, Indiana. Jim wrote to us to share the results of a seven month test of the product in American Aggregates’ mining equipment.
According to Jim, “We began treating each load of fuel on a regular basis. Probably like most people in the mining industry, having witnessed products with similar claims that just didn’t perform, I was skeptical. After using it for five months, I stopped and told no one.
Approximately two months later several of my underground equipment operators came to my office with air filters from their respective machines. They showed me how much carbon had been trapped and that the filters only had less than 80 hours of use. They wanted to know what kind of inferior fuel I had been buying. I informed them the fuel was the same, but DS-600i had been eliminated. Obviously they asked that DS-600i use be restarted.”
Before concluding his letter Jim added, “My operators have no complaints now about smoking problems, and MSHA give me regular compliments about our air quality underground. There not only is an obvious visible improvement in air quality, but it is also substantiated by the the air quality measurements taken daily.”
