• Engine Oil and Filter Change: Replaced with Bentley-specification fully synthetic oil .
• Hybrid Health Check: Comprehensive diagnostic scan of the hybrid system, including the battery management system and cooling systems .
• Multi-Point Inspection: Comprehensive check of brake pads and discs, steering and suspension components, tire condition and pressure, and all fluid levels (coolant, brake fluid, etc.) .
• Battery Condition Check: Inspection and testing of the 12-volt battery .

Major Service (20,000 miles / 24 months):

• All items from the Interim / Oil Service.
• Air Filter Replacement .
• Spark Plug Replacement .
• Wheels-Off Brake Inspection: In-depth inspection of brakes, including hub greasing .

Engine Oil Change Guidance

Oil Specifications

The V6 plug-in hybrid engine requires high-quality fully synthetic oil that meets Bentley's stringent factory standards . The oil change interval is 16,000 km (10,000 miles) or 12 months . The use of the correct oil is critical for maintaining vehicle performance and long-term reliability .

Oil Consumption Awareness

All internal combustion engines consume a small amount of oil for lubrication and cooling. The 2023 Flying Spur Hybrid is subject to normal oil consumption rates, which can vary based on driving conditions and engine characteristics . If the low oil level warning lamp illuminates on the instrument panel, it indicates replenishment is needed before the next scheduled service .

Hybrid System Maintenance

High-Voltage Battery and Cooling

The high-voltage battery system is a critical component of the hybrid powertrain. Routine maintenance includes checks of the battery management system and cooling systems as part of the annual service . The high-voltage battery is covered by a separate 8-year/80,000-mile warranty, providing long-term peace of mind .

Inverter Coolant

The hybrid powertrain includes an inverter system that requires its own cooling circuit. This coolant should be inspected regularly as part of the scheduled service .

Brake Fluid Service

Fluid Type and Service Interval

The 2023 Flying Spur Hybrid uses DOT-4 brake fluid . The brake fluid moisture content is tested at every service . A conservative approach is to flush and replace brake fluid every 2 years (32,000 km / 24 months), as it is hygroscopic and absorbs moisture over time, degrading braking performance .

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 provides essential information on the vehicle's features and maintenance procedures . A full Bentley service history from a recognised specialist carries significant weight in the market .

Specialist Care

Given the vehicle's complexity—especially the hybrid powertrain and advanced all-wheel-drive system—service should be performed by certified Bentley technicians or independent specialists with the right equipment and genuine parts . Independent specialists who follow the manufacturer’s schedule and use genuine parts can perform servicing that preserves the warranty .

Driving Habits and Storage

The Flying Spur Hybrid benefits from regular use. For vehicles not used regularly, a trickle charger is recommended to maintain the advanced electrical and hybrid systems . Following the manufacturer's recommended service schedule is the best way to prevent significant issues and expensive repairs .
