The less time an engine spends in service, the more productive it is on the job. That's why Cummins QST30 engines come with a high-capacity oil pan and pump. The increased capacity, along with advanced Fleetguard oil filters, let you operate the QST30 for up to 500 hours or 12 months between oil and oil filter changes.
Also standard is our PreLub system, which prevents starts without oil pressure and dry starts, resulting in an increased life-to-rebuild on every QST30.
