Factory Recommended Service Schedule

Primary Service Interval

Bentley's official service schedule for the 2026 Continental GTC is consistent with other modern Bentley models: every 12 months or 16,000 km (approximately 10,000 miles), whichever comes first . This is the foundational maintenance requirement for the vehicle.

The service interval warning system on the instrument cluster is triggered either by time or mileage, whichever occurs first. Even if the mileage threshold has not been reached, the service reminder will activate after 12 months.

Service Structure Progression

Based on established Bentley service patterns for the Continental GT/GTC range, the schedule follows a recurring progression of service types that increase in scope as the vehicle accumulates mileage . The typical progression is:

This 4-year pattern repeats throughout the vehicle's life .

Annual / 16,000 km Service Contents

At each scheduled visit, the following baseline items are typically performed:

• 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: All vehicle systems checked and topped up
• Suspension: Comprehensive inspection of all components, including the air suspension system
• Diagnostic Scan: Full vehicle systems check

Following the vehicle inspection, owners are informed of any components not meeting specification, at which point they can approve any necessary repairs.

Service Types Breakdown

Based on specialist service guidance for the Continental GT range, the service types include specific items at each milestone :

A Service (Annual / 16,000 km):

• Full vehicle inspection
• Replace wiper blades, key fob batteries
• Engine oil and filter change
• Pollen filter replacement

B Service (Additional at 32,000 km / 24 months):

• All A Service items
• Brake fluid change
• Air filter replacement

Engine Oil Specifications

Approved Oil

The 2026 Continental GTC's V8 hybrid engine requires Exxon Mobil 1 ESP X4 0W-40 engine oil (Bentley part number GA555792B) . This oil is specifically formulated to meet the demands of the new V8 hybrid powertrain and provides superior lubrication for the engine's high-performance components .

Oil Capacity

The basic oil fill capacity for the 4.0L V8 hybrid engine (engine code CVDA/DVTC) is 11 liters .

Oil Change Interval

• Factory recommendation: Every 12 months or 16,000 km
• Conservative owner guidance: Never exceed 12 months for an oil change, even if the mileage is low, as synthetic oil can degrade over time. For vehicles driven primarily in extreme climates or for short urban journeys, some specialists recommend more frequent changes.

Spark Plug Timing

Replacement Interval

Spark plugs are typically replaced during the third-year service (approximately 48,000 km / 36 months) as part of the C Service .

Part Specifications

For the 2026 Continental GTC, the spark plug part number is 0P2905601C, which is specifically designed for the New Continental Convertible, New Continental GT, and New Flying Spur models . Earlier Continental GTC models use a different spark plug (part number 101905600B) and the correct part must be verified for your specific vehicle .

Brake Fluid Service

Fluid Type and Replacement Interval

The 2026 Continental GTC uses DOT-4 brake fluid. The brake master cylinder with integrated fluid reservoir (part number 976616123) is a critical component of the braking system .

• Inspection: Brake fluid level and condition should be inspected at every scheduled service.
• Replacement: Brake fluid is typically replaced as part of the B Service, which occurs at 32,000 km / 24 months .

Brake fluid is hygroscopic and absorbs moisture over time, which can degrade braking performance and potentially damage the braking system. Adherence to the replacement schedule is essential for safety.

Long-Term Ownership Considerations

Service Documentation

Maintaining a comprehensive service history is critical for preserving the vehicle's resale value. A full Bentley service history from a recognized specialist carries genuine weight in the market. Service records should document all work performed, including oil changes, brake fluid services, and major service items.

Specialist Care

Given the vehicle's complexity—especially the V8 hybrid powertrain and all-wheel-drive system—service should be performed by certified Bentley technicians or independent specialists with the right equipment and genuine parts.

Battery and Charging System

As a plug-in hybrid, the 2026 Continental GTC's high-voltage battery and charging system require regular inspection as part of the service schedule. Battery condition and cooling system checks should be included in the annual service.

Driving Habits and Storage

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