Royal Purple 55520 SAE 5W-20 High Performance Synthetic Motor Oil 5-Quart

Royal Purple 55520 is a SAE 5W-20 full synthetic motor oil engineered for high performance and maximum engine protection. Formulated with Royal Purple's proprietary Synerlec additive technology, this oil creates a stronger, more durable film on metal surfaces than conventional or competing synthetic oils, reducing friction and wear even under severe operating conditions.

Royal Purple 5W-20 is fully compatible with conventional and other synthetic motor oils and is safe for use in gasoline and flex-fuel (E85) engines. It exceeds the requirements of API and ILSAC standards, making it suitable as a direct replacement for OEM-specified 5W-20 motor oils.

Key Features:

• Synerlec Technology: Proprietary additive package that dramatically increases film strength for superior wear protection
• Full Synthetic Formula: Provides excellent cold-start protection with fast oil flow in low temperatures
• Friction Reduction: Minimizes metal-to-metal contact to help improve fuel efficiency and power output
• Corrosion Protection: Neutralizes acids and guards against rust and corrosion within the engine
• Extended Drain Intervals: Maintains viscosity and performance characteristics longer than conventional oils
• API & ILSAC Certified: Meets or exceeds current API service and ILSAC GF-6 performance standards
• Compatible with Catalytic Converters: Safe for use with all emission control systems

Royal Purple 55520 5W-20 synthetic motor oil is the ideal choice for drivers seeking premium lubrication technology that delivers measurable improvements in engine protection, efficiency, and longevity. Suitable for modern gasoline engines requiring a 5W-20 viscosity grade.
