About This

• 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.
• Cold-Start Performance: The 5W winter grade flows fast at low temperature for quick lubrication at startup, and a 428F flash point holds the oil stable under sustained engine heat.
• One Gallon Fill: Covers a top-off or partial change. A full service is about 12 quarts on 6.7L Cummins, 13 on 6.7L Powerstroke, and 10 on 6.6L Duramax. Confirm 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.
