“Prior to using Gen 49D, we were using an average of 900 gallons a day of diesel fuel per drilling rig.  With the addition of Gen 49D we now are averaging 810 gallons per day per drilling rig.  As an added bonus, due to the lubricating properties of Gen 49D, we now get extended fuel pump life and through the detergents present in the additive, our injectors are far cleaner.”
