Factory Recommended Service Schedule

Primary Service Interval

Bentley's official service schedule for the 2025 Continental GTC is consistent with other modern Bentley models: every 12 months or 16,000 km (approximately 10,000 miles), whichever comes first . Some market specifications list a 15,000 km interval, so owners should verify the exact interval for their region.

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.

Engine Oil Change Guidance

Oil Specifications

The 2025 Continental GTC's V8 hybrid engine requires high-quality fully synthetic oil that meets Bentley's factory standards. The exact specification should be verified from the owner's manual for your specific vehicle. Modern Bentley engines using synthetic oil are engineered to go between 7,500 and 15,000 miles between oil changes.

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, many specialists recommend more frequent changes.

Brake Fluid Service

Fluid Type and Replacement Interval

The 2025 Continental GTC uses DOT-4 brake fluid.

• Inspection: Brake fluid level and condition should be inspected at every scheduled service.
• Replacement: Brake fluid is typically replaced at the 24-month or 32,000 km service.

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

Spark Plug Timing

Replacement Interval

Spark plugs are a significant service item on the Continental GTC's high-performance V8 engine. Replacement is typically included in the 3rd Annual service at 48,000 km or 36 months.

The 4.0L V8 engine requires a full set of spark plugs. Given the high-performance nature of the engine, adherence to the factory-recommended replacement schedule is essential for maintaining optimal ignition performance, fuel efficiency, and engine health.

Transmission Service Guidance

The requirement for a transmission fluid change depends on several factors. 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 . Stop-and-go driving, spirited driving, or other high-stress conditions can shorten transmission fluid life.

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.

Fuel Filter Service

Changing the fuel filter is part of the repair and maintenance schedule for the 2025 Continental GTC. Many car companies 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 will provide the most specific information for your vehicle.

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 2025 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.
