Castrol EDGE 5W-20 Full Synthetic Motor Oil, 5 Quart — Advanced Wear Protection & Thermal Stability

Castrol EDGE 5W-20 is a full-synthetic engine oil formulated to deliver strong wear protection, thermal stability, and consistent viscosity for modern gasoline engines.

Engineered for drivers who expect dependable performance under varied conditions, Castrol EDGE 5W-20 blends advanced base oils and proprietary additives to maintain oil film strength, reduce deposits, and support efficient operation. This 5-quart container is sized for routine service and offers the performance specifications required by many contemporary vehicles.

How does Castrol EDGE 5W-20 protect my engine under stress?

EDGE uses a high-strength synthetic formulation that resists oil film breakdown when the engine is pushed hard or runs hot. That helps reduce metal-to-metal contact and slows component wear, especially in high-stress situations like towing or aggressive driving.

• Formulated for stronger film strength to resist shear and maintain viscosity
• Helps reduce wear on critical components such as camshafts and bearings
• Proprietary additives manage friction and surface protection under load

Will this oil help with fuel economy and high-temperature performance?

Yes—the low-viscosity 5W-20 grade is designed to flow quickly at start-up and maintain stability at operating temperatures, supporting smoother operation and potential fuel-efficiency benefits. The synthetic base stocks and thermal control additives reduce breakdown at high temperature, helping to keep oil properties consistent over time.

• Low-viscosity formula improves cold start flow and reduces pumping losses
• Thermal stability minimizes deposit formation and oil degradation at high temps
• Tested to maintain performance over extended intervals where vehicle specs allow

How long can I go between oil changes with Castrol EDGE 5W-20?

Castrol highlights extended performance capabilities, with formulated durability that supports longer drain intervals when permitted by your vehicle manufacturer. Always follow your carmaker’s recommended service schedule; extended intervals depend on driving conditions and factory recommendations.

• Designed for extended protection and stability between services when approved
• Consult your vehicle owner’s manual for manufacturer-specified oil change intervals
• Performance claims assume normal operating conditions and proper vehicle maintenance

Is this oil compatible with my vehicle's specifications?

Castrol EDGE 5W-20 meets a range of industry and manufacturer requirements, making it suitable for many modern gasoline engines. Check the approvals and your vehicle’s recommended oil standards to confirm fitment.

• Exceeds API SQ/SP/SN PLUS/SN and meets ILSAC GF-7
• Meets Chrysler MS 6395 and Ford WSS-M2C945-B1 / WSS-M2C960-A1 requirements
