Doc's Diesel 5W-40 Full Synthetic Heavy Duty Oil, CK-4 Cold Start, 3 Gal

• 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.
• 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.
