Product Details

Royal Purple Duralec Super SAE 15W-40 is a premium synthetic diesel motor oil engineered to deliver superior protection and performance in heavy-duty diesel engines. This advanced formula combines Royal Purple's proprietary Synerlec additive technology with high-quality synthetic base oils to provide exceptional wear protection, extended oil life, and improved fuel efficiency.

Key Features:

  • Enhanced wear protection reduces engine component wear by up to 50% compared to leading synthetic diesel oils
  • Superior soot control keeps engines cleaner and maintains optimal oil flow
  • Improved oxidation stability extends oil drain intervals and reduces operating costs
  • Excellent low-temperature performance ensures reliable cold starts and rapid oil circulation
  • Compatible with all diesel fuels including ultra-low sulfur diesel (ULSD) and biodiesel blends
  • Meets or exceeds API CK-4, CJ-4, CI-4 PLUS, CI-4, and CH-4 specifications
  • Recommended for on-highway and off-highway diesel applications

Ideal for use in turbocharged and naturally aspirated diesel engines found in commercial trucks, agricultural equipment, construction machinery, and marine applications. Royal Purple Duralec Super provides outstanding protection under severe operating conditions including high loads, extreme temperatures, and extended service intervals.
