Royal Purple Duralec Ultra High Performance Motor Oil With Synerlec
Royal Purple Duralec Ultra motor oil is specifically formulated to maximize performance and meet the demands of today’s heavy-duty engines. Duralec Ultra is fortified with a high level of zinc/phosphorus anti-wear additive and Royal Purple’s proprietary Synerlec® additive technology.
Synerlec creates a tenacious ionic bond with metal surfaces, which protects engines by providing instant wear protection upon startup. This state of the art technology also responds to increased pressure with increased film strength and improves the condition of metal-to-metal contact under severe conditions for greater protection.
Duralec Ultra provides a lower coefficient of friction to save fuel and its synthetic solvency keeps internal engine parts cleaner than detergents alone. With superior oxidation stability that greatly extends drain intervals and minimizes harmful oil degradation, Duralec Ultra outperforms leading synthetics and conventional lubricants for both gasoline and diesel engines.
Duralec Ultra motor oil is recommended for use in both two-cycle and four-cycle diesel applications including automotive, commercial fleet and stationary industrial diesel engines.
• Greater Wear Protection
Duralec Ultra ’s advanced additive technologies form a tough, tenacious film on all metal surfaces virtually eliminating engine wear.
• Greatly Extends Oil Drain Intervals
Duralec Ultra 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
Duralec Ultra ’s advanced additive technologies protects during normal and severe operation and acts as a preservative oil during shut-down, which provides protection upon initial startup.
• Saves Fuel
Duralec Ultra Motor Oil’s low coefficient of friction routinely produces meaningful improvements in fuel economy.
• Reduces Exhaust Emissions
Duralec Ultra provides a superior seal between the piston ring and cylinder wall, which reduces blow-by, improves combustion efficiency and measurably reduces harmful emissions.
• Increases Horsepower
Duralec Ultra increases horsepower and torque over conventional oils.
• Keeps Engines Clean
Duralec Ultra Motor Oil’s natural solvency cleans deposits left by old oils and keeps engines clean.
• Mates Engine Parts
Duralec Ultra ’s advanced additive technologies allow engine parts to perfectly mate. Mated parts allow engines to run smoother with increased efficiency for maximum performance.
• API Warranty Compliant
Duralec Ultra ’s SAE grade motor oils are API licensed. They are compatible with other mineral and synthetic motor oils. Switching is easy. Drain old oil. Change the filter. Add Duralec Ultra Motor Oil. Follow manufacturer’s recommended drain intervals during warranty.
• Will Not Harm Seals
Duralec Ultra Motor Oil has the same excellent seal compatibility as mineral engine oils.
• Environmentally Responsible
Duralec Ultra Motor Oil components are TSCA listed and meet EPA, RCRA and OSHA requirements. Duralec Ultra extends oil drain intervals, eliminates premature oil changes, decreases the amount of oil purchased and disposed of and conserves energy
