Engine Oil Service

Oil Change Interval

The 4.0L twin-turbo V8 in the DBX V8 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 .

Parts and Lubricants Warning

Aston Martin recommends using the specified lubricants and parts when performing service tasks. If oils or lubricants that do not meet the required specifications are used, vehicle components may experience excessive wear, sludge and deposits, or increased pollution. If damage is caused by using products other than those recommended by the manufacturer, Aston Martin may refuse warranty coverage for such repairs .

Brake Fluid Service

Replacement Interval

Brake fluid replacement is scheduled at the 32,000 km / 24-month service interval . 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.

Cooling System Service

Coolant Replacement

Coolant replacement is scheduled at the 6-year / 96,000 km service interval . Always use the specified coolant type for the 4.0L V8 engine. The cooling system should be inspected at each regular service interval.

Owner Check Procedure

• The coolant level should be at the top of the reservoir tank
• Do not remove the filler cap until the system has cooled; scalding can be caused by escaping steam or coolant
• Use a cloth or glove to protect hands and face when checking coolant

Spark Plug Service

Replacement Guidance

The DBX V8's 4.0L engine requires spark plugs that meet the manufacturer's specifications. You should always use the spark plugs recommended in the owner's manual for your vehicle. The engine has been optimized to function with specific spark plug characteristics, and using plugs different from the manufacturer's recommendation can affect engine performance.

General Guidance for Spark Plug Replacement:

• Ideally, check spark plugs after driving 30,000 miles (50,000 km) to assess their condition
• Replacement is typically due between 35,000 and 60,000 miles (60,000 to 100,000 km), depending on driving style and fuel quality

Transmission Service

The DBX V8 is equipped with a 9-speed automatic transmission . For automatic transmissions, service intervals vary by manufacturer—some vehicles may never require transmission fluid changes unless there is a leak or other issue . Following Aston Martin's specific guidelines for transmission maintenance is important, as a transmission rebuild can cost up to $6,000 or more . Always consult your Aston Martin dealer for the specific transmission service interval for your DBX V8.

Extended Maintenance Guidance

The following table summarizes core maintenance intervals for the DBX V8 based on fixed-price servicing information :

Note: Always verify exact intervals for your specific vehicle in the official owner's manual .

Extended Warranty and Service Plans

At the end of the 3-year factory warranty period, Aston Martin offers extended warranty coverage. An optional extended Premium service contract can extend from two years all the way out to 10 years with unlimited mileage. The plans are available on road-going models less than 10 years old, subject to a multi-point Aston Martin inspection. All services are performed by factory-trained technicians using genuine Aston Martin parts.
