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.
  • Built For Heat And Load. The 15W-40 grade holds a strong oil film for towing and high-load work, and a 414F flash point stays stable under sustained engine heat.
  • Three Gallon Fill. Twelve quarts covers a full 6.7L Cummins or 6.6L Duramax change. The 6.7L Powerstroke needs about 13 quarts, so choose four gallons. Confirm in your 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.
