About Royal Purple High Performance Engine Oils

Royal Purple Duralec Super motor oil is a high performance engine oil made for emission-controlled diesel engines utilizing emissions equipment such as: DPF’s, Catalytic Converters, EGR, and SCR injection. Royal Purple Duralec Super is an API CK-4 engine oil. Royal Purple Duralec Super motor oil is specifically formulated to maximize component life, extend drain intervals and improve fuel performance. These premium lubricant formulations provide excellent high temperature resistance and low temperature pumpability, outstanding soot dispersancy, improved rust and corrosion protection, and prevention of varnish and sludge formation.

Performance Advantages:

  • Greater Wear Protection: Prevents wear of piston rings, valve train, and other components beyond CK-4 requirements
  • Greatly Extends Oil Drain Intervals: Enhanced oxidation resistance reduces oil aging, acidity build-up, and viscosity increase
  • Superior Corrosion Protection: No rust observed in standard industry testing
  • Reduces Exhaust Emissions: Highly stable and protective formula improves cylinder seal and protects emissions equipment
  • Outstanding Deposit Control: Keeps engines cleaner, ensuring maximum performance
  • Low Ash Formulation: Satisfies requirements of engines requiring the use of API CK-4 and CJ-4 reduced SAPS specifications
