While the upfront cost of synthetics is higher, the extended drain intervals and protection against deposit formation often result in a lower net cost of ownership for commercial operators. Best Practices for Oil Change Intervals Extending oil drain intervals is a common goal, but it requires the right foundation.

15W-40 has been the traditional standard for on-highway applications, providing a balance between high-temperature protection and cold-weather fluidity. Cummins has specific approval protocols, such as CES 20071 and CES 20072, which validate that the oil meets the exact requirements for warranty coverage and optimal performance in their engines.
By testing samples, technicians can assess viscosity breakdown, contamination levels, and additive depletion, allowing for data-driven decisions on when to perform maintenance rather than relying on arbitrary mileage counts. High levels of phosphorus or zinc can poison the catalysts, while excessive ash can clog the DPF.

Conventional Blends The debate between conventional mineral oil and synthetic technology centers on performance and longevity. They also exhibit better low-temperature pumpability, reducing wear during startup and delivering cleaner engine performance over the life of the oil.
