About this product
- Proven In Testing. Independent testing showed up to 71 percent less engine wear in the Cummins ISM severe service run and up to 78 percent lower oil consumption against the CK-4 specification in the CAT 1N test.
- Fits Your Diesel. Runs in Cummins, Powerstroke, and Duramax trucks, fleet vehicles, and equipment, and is compatible with the 3.0L EcoDiesel.
- Lower Drag Formula. The lighter 10W-30 grade cuts internal friction for improved fuel economy, and a 435F flash point holds the oil stable under sustained engine heat.
- Four Gallon Fill. Sixteen quarts covers a full change on 6.7L Cummins, 6.7L Powerstroke, or 6.6L Duramax with oil to spare. Confirm exact capacity in your owner manual.
- Service Intervals. Change every 10,000 to 15,000 miles on normal duty, or 7,500 to 10,000 under heavy towing and severe use. Meets the GHG 17 emissions standard for modern diesels.
