About This

  • Fleet Value: A semi synthetic CK-4 oil that delivers dependable wear and heat resistance at a lower cost per change than full synthetic, built for high-mileage fleets and routine service.
  • Fits Your Diesel: Runs in Cummins, Powerstroke, and Duramax trucks, fleet vehicles, and equipment on normal and severe duty.
  • Heat And Shear Stability: Holds viscosity under load with strong oxidation and thermal control, and a 441F flash point keeps the oil stable through sustained high-temperature operation.
  • Shop And Fleet Drum: Fifty-five gallons for high-volume service bays and fleets, roughly four to five 6.7L truck changes per drum. Pair with a pump for clean dispensing.
  • Service Intervals: Change every 10,000 to 15,000 miles on normal duty, or 7,500 to 10,000 under heavy loads. Low-ash chemistry meets the GHG 17 emissions standard for modern diesels.
