2016 Bentley Mulsanne Complete Service & Maintenance Schedule

The 2016 Bentley Mulsanne represents the ultimate expression of British luxury saloon engineering, powered by a hand-built 6.75L twin-turbo V8. As a flagship motorcar of immense complexity, a disciplined and well-documented maintenance schedule is the cornerstone of preserving its performance, reliability, and substantial investment value. The factory-recommended schedule is once a year or every 10,000 miles (approximately 16,000 km), whichever comes first.

Key Takeaways

• Primary Service Interval: Scheduled maintenance is required every 12 months or 16,000 km (approximately 10,000 miles), whichever comes first.
• Engine & Performance: Powered by a 6.75L twin-turbo V8 producing 505 hp and 752 lb-ft of torque, with rear-wheel drive. The engine has a basic oil fill capacity of 9.4 liters.
• Factory Warranty: New 2016 models were protected by a comprehensive 3-year/unlimited mileage factory warranty, which also included maintenance coverage for the same period.
• Service Indicator: The vehicle is equipped with a standard service interval warning system on the instrument cluster.
• Service History: Maintaining a comprehensive service history is critical for preserving the vehicle's resale value. The official owner's manual is the definitive source for maintenance requirements.

Factory Recommended Service Schedule

Primary Service Interval

Bentley's official service guidelines are simple and consistent: the 2016 Mulsanne requires a service once a year, or every 10,000 miles (approximately 16,000 km), whichever comes first. The first year of Bentley service is complimentary for the original owner.

Annual / 16,000 km Service Contents

At each scheduled visit, a comprehensive inspection and service is performed. This typically includes:

• Engine Oil & Filter: Replaced with Bentley-specification fully synthetic oil.
• Cabin Pollen Filter: Replaced.
• Windshield Wipers: Replaced as needed.
• Key Fob Battery: Replaced.
• Brake System: Comprehensive inspection of brake pads and discs, fluid levels, and hoses.
• Fluid Levels: All vehicle systems (coolant, brake fluid, power steering, transmission) checked and topped up.
• Leakage Inspection: Visual inspection for fluid leaks from the engine and transmission.
• Suspension: Comprehensive inspection of all steering and suspension components, including air springs, for wear and damage.
• Air Filter: The engine air filter is inspected at every service and replaced as needed, typically every 15,000–30,000 miles depending on driving conditions.
• Lighting & Wipers: Operational check of all external lights, horn, and wipers.

Following the vehicle check, owners are informed of any components that are not up to specification, at which time they can approve any necessary repairs.

Service Structure Progression

Bentley service schedules follow a recurring pattern of service types that increase in scope as the vehicle accumulates mileage. While the primary factory-scheduled service remains the annual 10,000-mile inspection, the schedule may progress in complexity at higher intervals, typically following an Interim, Full, and Major service structure on an annual or 12,000-mile cycle.

Engine Oil and Filter Change

Oil Specifications

The 6.75L twin-turbo V8 in the Mulsanne requires high-quality fully synthetic oil meeting Bentley's stringent factory standards. The engine has a basic oil capacity of 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).

Brake System

The 2016 Mulsanne's braking system requires regular inspection and maintenance to ensure safety and performance.

Brake Fluid

Brake fluid is hygroscopic and absorbs moisture over time, which can degrade braking performance. A conservative and recommended approach is to flush and replace the brake fluid every 2 years (24 months), regardless of mileage. The brake fluid is checked for strength and level at each service.

Brake Components

At each service, brake pads, discs, and calipers are inspected for wear, leaks, and security.

Air Filter

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. Driving in severe or dusty conditions may require more frequent changes.

Cabin Air Filter

The cabin air filter, which removes pollen and pollutants from the interior's HVAC airflow, is located behind the glove box or under the dash and is typically replaced during a major service.

Transmission and Fluids

Transmission Service

The 2016 Mulsanne is equipped with a sophisticated automatic transmission. Specialist service centres typically check the transmission for fluid leaks as part of a standard service.

The question of whether a transmission fluid change is required depends on the specific application and the guidelines in the owner's manual. Some modern transmissions are designed to never need a fluid change unless there is a leak or other problem. It is crucial to follow the specific guidelines outlined in the Bentley Owner's Manual for the definitive service interval.

Long-Term Ownership Considerations

Service Documentation

Maintaining a comprehensive service history is critical for preserving the vehicle's resale value. The official operating instructions manual for the 2016 Mulsanne is an essential resource for understanding the vehicle's features, controls, and maintenance procedures. Service records should document all work performed, including the use of Bentley-specification parts and fluids.

Specialist Care

Given the vehicle's complexity, service should be performed by certified Bentley technicians or independent specialists with the right equipment and access to genuine parts. Independent service centres that follow the manufacturer's schedule and use OEM parts can perform servicing that maintains the vehicle's warranty and value.
