Now that some heavy duty diesel vehicles are using advanced lubrication systems, they need fewer oil changes. Cummins engines are now able to drain and change oil every 35,000 to 50,000 miles depending on if they are X15 or X12 models. Detroit DD13 and Volvo engines can go to 60,000 miles before changing oil is recommended, International’s A26 can go up to 70,000 before a change, but check specifications. Be sure to check with your engine manufacturer as well as the oil provider for specifics because your gas mileage will be affecting by your engine’s performance.
- The oil drain interval (ODI) recommendations for Cummins trucks are: 5.5 to 6.5 MPG range, X15 efficiency and performance is 35,000 miles; 6-6.9 MPG range is 50,000 miles.
- The ODI for Detroit DD13 is that the oil and filter should be changed every 35,000 miles while for long haul, the average is 60,000 annual miles.
- To extend the oil drain interval for a truck in a fleet, it is recommended that the fleet manager should not go it alone. Involve the oil supplier.
