Engine Oil Change Guidance

Oil Specifications

The 6.75L twin-turbo V8 requires high-quality fully synthetic oil meeting Bentley's stringent factory standards. The engine has a basic oil fill capacity of approximately 9.4 liters. Specialist services typically include replacing the engine oil and filter .

Oil Change Interval

The factory recommendation is to change the engine oil and filter every 12 months or 16,000 km (10,000 miles) . Even if the mileage is low, an annual oil change is recommended because engine oil degrades over time .

Transmission Service

Service Considerations

The 2017 Mulsanne EWB is equipped with an 8-speed ZF automatic transmission . The question of how often to change transmission fluid depends on several factors.

Important Guidance: Some modern transmissions are designed to never need a fluid change unless there is a leak or another problem, while others have a regular maintenance interval. It is crucial to follow the specific guidelines outlined in the Bentley owner's manual for the 2017 Mulsanne EWB .

Warning Signs

If shifting becomes rough, delayed, or is accompanied by unusual noises or lurching, have the transmission inspected immediately by a Bentley service center.

Brake System

Brake Fluid

Brake fluid is hygroscopic and absorbs moisture over time, which can degrade braking performance. A conservative approach is to flush and replace the brake fluid every 2 years, regardless of mileage . The brake fluid is checked for condition at each service.

Brake Components

At each service, brake pads, discs, and calipers are inspected for wear, leaks, and security . The Mulsanne EWB features carbon-ceramic disc rotors for maximum stopping power . With the vehicle's substantial weight (approximately 2,700 kg), brake components may wear more quickly than on lighter vehicles . Regular inspection is essential to avoid costly secondary damage.

Additional Service Items

Engine Air Filter

The engine air filter protects the 6.75L V8 and its twin-turbo system from dust and debris. It is inspected at every service and, under normal conditions, replaced as needed, typically every 15,000–30,000 miles depending on driving conditions . Driving in severe or dusty conditions may require more frequent changes.

Fuel Filter

Changing the fuel filter is part of the repair and maintenance schedule for the Mulsanne. Many manufacturers recommend changing the fuel filter every 5 years or 50,000 miles, though this may vary based on driving habits and local fuel quality . The owner's manual provides the most specific information for your vehicle.

Service Documentation

Maintaining a comprehensive service history is critical for preserving the vehicle's resale value. The official owner's manual for the 2017 Mulsanne is the definitive source for maintenance requirements and should be kept in the vehicle for reference.

Cost Awareness

Owning a Bentley Mulsanne comes with significant maintenance costs. Routine services can be substantial, and even minor repairs can become quite expensive. It is essential for owners to budget adequately for these expenses.
