Yes. Viscosity is only one part of the oil spec. Match the oil approval listed in your owner's manual or on the bottle before checkout.
How often should I change the oil on a 2021 Aston Martin DBX?
Castrol's service data indicates a 10,000 mi / 12 mo change interval for the 2021 Aston Martin DBX. Always follow your owner's manual and oil-life monitor. Severe service may require a shorter interval.
Do I need a new drain plug gasket?
Replace it when your vehicle uses a serviceable gasket or crush washer. Confirm the gasket size and drain plug torque from the service manual or parts counter.
