Las Vegas (March 15, 2005) - Cummins Inc. (NYSE:CMI) announced that the CENTINEL™ Advanced Engine Oil Management System is now available as an aftermarket kit for the QSX, QSK19, QSK45 and QSK60 engines rated between 350-3000 (261-2238 kW) horsepower. CENTINEL, formerly only available as a new engine option, can be easily purchased and installed at any Cummins distributor location allowing Cummins powered equipment operators to take advantage of this cost and time saving technology even if the machine did not initially have this capability. Cummins is focused on helping the operator reduce operating costs while maintaining the highest levels of uptime in the industry.

The CENTINEL Advanced Engine Oil Management System enables equipment operators to extend oil change intervals to as much as 4,000 hours. Depending on the platform, the extension equates to removing 15-20 oil changes and thereby reduces maintenance time and expense. CENTINEL integrates with Cummins full authority electronics, allowing the engine to blend lube oil with fuel prior to engine combustion and adjusts the burn rate based on the equipment load factor. The system is available with reserve tanks for continuous oil replenishment.

Further maintenance interval extensions can be achieved with the addition of the ELIMINATOR™ oil filtration system, a full-flow and centrifugal system that incorporates a permanent core. By eliminating the need to replace and dispose of used oil filters, lube system maintenance costs are reduced by as much as 90%.
