Engine Oil Service

Oil Change Interval

The 4.0L twin-turbo V8 in the DBX requires a synthetic oil and filter change at the 16,000 km or 12-month service interval .

Owner Oil Level Check

Aston Martin recommends checking the engine oil level regularly between services. Running the engine with oil below the lower mark or above the upper mark can cause serious engine damage. Only use high-quality fully synthetic oil meeting manufacturer specifications.

Brake Fluid Service

Replacement Interval

Brake fluid replacement is scheduled at the 32,000 km / 24-month service interval according to general guidance for the DBX. This safety-critical service should not be deferred. Brake fluid absorbs moisture over time, which reduces its boiling point and can lead to brake fade under hard use.

Air Filter Service

Ancillary Drive Belt Service

The ancillary drive belt is scheduled for replacement at the 48,000 km / 36-month service interval. This is a critical maintenance item that should not be deferred, as belt failure can lead to loss of alternator, power steering, or air conditioning function.

Service Interval Reset

Aston Martin Technical Service Bulletin SB-30-1669 addresses the service interval reset process for the 2022 DBX . Dealers are required to reset the service interval timer during the customer handover process for vehicles that have spent time in stock or storage. For DBX, the reset must be performed using the instrument cluster process, with a labour time of 0.05 hours .
