The Cummins QSX was designed to minimize maintenance requirements and maximize your uptime. That's why oil drain intervals for the Cummins QSX are set for 625 hours or six months. Filters are vertically mounted for easy access and rapid changing, with no messy spills. Advanced Fleetguard® ES oil and fuel filters allow 500-hour service intervals. Polyvee belts have auto-tensioners, so they never need adjusting. Plus, with the QSX you won't need to adjust the overhead for 3,000 hours.
Dipsticks and oil fills are available from both sides of the engine. And there are three drain ports available, so you never have to worry about having access to maintenance points.
