How does this oil protect my engine at high temperatures?

EDGE Extended Performance delivers reinforced film strength and resistance to viscosity breakdown under heat. That means the oil resists thinning and continues to lubricate moving parts when engine temperatures climb, reducing metal-to-metal contact.

• Designed for high thermal stability to limit viscosity loss in demanding conditions
• 50x better high-temperature performance in controlled tests versus standard limits
• Proprietary additives maintain protective oil film on critical engine components

Can it really support longer drain intervals?

This formulation is engineered to retain its protective properties over extended mileage when used in appropriate applications and intervals recommended by Castrol and vehicle manufacturers. Extended drains up to 25,000 miles are achievable under suitable conditions and following manufacturer guidance.

• Formulated for extended drain capability: up to 25,000 miles or one year, whichever comes first
• Maintains viscosity and additive effectiveness over prolonged service
• Use only when vehicle manufacturer allows extended drain intervals

Which vehicles and specifications does this 5W-30 oil support?

Castrol EDGE 5W-30 meets a wide range of industry and OEM specifications, making it compatible with many modern gasoline engines and some light-duty turbocharged engines. Always check your owner's manual to confirm 5W-30 is the correct viscosity for your vehicle.
