Bill Barrett Corporation started using DS-600i in May 2008. They measured an increase drill time (hours per gallon) that equated to a savings of 16.3%.
Bill Barrett also reported that all of the engines running on treated fuel had stopped smoking while under load by the end of the test. Although the usual black puff of unburned diesel was and will continue to be visible during the brief periods of acceleration, all smoke disappeared once each engine was operating under load at peak RPM.
