PERFORMANCE ADVANTAGES

  • Greater Wear Protection Duralec Super’s advanced additive technologies form a tough, tenacious film on all metal surfaces providing superior engine wear protection.
  • Greatly Extends Oil Drain Intervals Duralec Super Motor Oil is extremely oxidation stable and stands up to the heat that causes oils to thicken, form lacquer and varnish deposits, lose its lubricity and shorten the life of both the oil and the engine.
  • Superior Corrosion Protection Duraiec Super’s advanced additive technologies protect during normal and Severe operation and act as preservative oil during shut-down, which protects initial startup.
  • Reduces Exhaust Emissions Duralec Super Motor OiJ provides a superior seal between the piston ring and cylinder wall, which reduces blow-by, improves combustion efficiency and reduces harmful emissions.
  • Keeps Engines Clean Duralec Super Motor Oil’s natural solvency cleans deposits left by old oils and keeps engines clean.
