We have been monitoring Maintenance Practices over a period of several years, particulary on engines operating in the Drilling Industry and have observed a trend of what we believe to be over maintaining. In our view this practice needs to be reviewed taking into consideration a number important factors impacting operating cost, Equipment reliability and the Environment.
Traditionally organizations owning and operating Equipment implement Maintenance schedules as per standard OEM recommendation, which are nasally time based without fully understanding the benefits and limitations. Managers often see Maintenance as a cost center rather than a profit center.
Many of engine manufacturers around the world acknowledge that extending oil change intervals is an acceptable practice, providing the recommended oil is used, operating conditions are taken into consideration and a reliable Fluid Analyses program is in affect.
