Castrol EDGE 5W-30 Full Synthetic Motor Oil, 6-Quart EcoPack — Advanced High-Mileage Protection

Castrol EDGE 5W-30 Advanced Full Synthetic Motor Oil (6 Quarts EcoPack) is a high-performance synthetic oil formulated to protect and rejuvenate engines with over 75,000 miles while helping preserve emission system components.

If your vehicle has logged significant miles and you want an oil that fights leaks, reduces oil consumption, and helps prevent deposit build-up, this Castrol EDGE formulation is engineered for those needs. It uses a proprietary phosphorus replacement technology to lower phosphorus exposure to the catalytic converter while delivering full synthetic protection and long drain intervals. The 6-quart EcoPack provides enough oil for most oil changes and minimizes packaging waste compared with multiple smaller containers.

How does this oil help older engines perform better?

Castrol EDGE 5W-30 is designed to address common high-mileage engine concerns such as seal shrinkage, oil burnoff, and internal deposits. Its chemistry helps maintain oil film strength under stress, which can reduce friction-related power loss and wear.

• Formulated to reduce leaks and slow oil consumption in worn seals and gaskets
• Helps minimize power-robbing deposits that form with age
• Maintains film strength to protect moving parts under pressure

Will this oil protect my vehicle’s emission system?

This Castrol product includes Phosphorus Replacement Technology to limit harmful phosphorus that can damage catalytic converters. While not a cure-all, the reduced phosphorus content helps protect emission control components over time compared with conventional formulations that contain higher phosphorus levels.

• Special additive package engineered to be gentler on catalytic converters
• Supports emission-system longevity in high-mileage cars
• Meets industry specifications related to emission-system performance

How long can I go between oil changes with this oil?

Castrol recommends up to 15,000 miles between oil changes or one year, whichever comes first, under appropriate driving conditions. Actual drain intervals depend on vehicle make, driving style, and operating conditions—always follow your vehicle manufacturer’s maintenance guidance.

• Rated for up to 15,000-mile intervals in suitable conditions*
• Synthetic base and additive system designed for extended protection
• Check owner’s manual and driving habits before extending intervals

Is this oil compatible with my car’s required specifications?

Castrol EDGE 5W-30 meets or exceeds key industry and OEM specifications, making it suitable for a wide range of modern engines. It carries API SP/SN PLUS/SN/SM and ILSAC GF-6 approvals and meets several Ford and Chrysler requirements, but always verify the required viscosity and specification for your exact engine model.

• API SP/SN PLUS/SN/SM and ILSAC GF-6 compliant
• Meets Chrysler MS 6395 and Ford WSS-M2C946-B1 / WSS-M2C961-A3 test requirements
• Suitable for many gasoline engines that call for 5W-30 synthetic oil

Who is this for: drivers of high-mileage gasoline vehicles (typically over 75,000 miles) who want a full synthetic motor oil that targets leak reduction, reduced oil burnoff, and deposit control while being mindful of emission system longevity. Ideal for motorists seeking a long-drain synthetic oil packaged in an eco-friendlier 6-quart container for typical oil changes. Always confirm compatibility with your vehicle handbook before use.

*Or one year, whichever comes first. Follow vehicle manufacturer recommendations for oil change intervals.
