BMW M8 F91/F92/F93 Maintenance Guide
BMW M8 (inc. Competition) Maintenance Guide
The BMW M8 and M8 Competition, with their high-performance twin-turbo V8 engines, sophisticated technology, and premium materials, are designed to deliver both thrilling driving experiences and everyday comfort. For owners or potential buyers of these models in the UK, maintaining the M8 to keep it performing at its best is essential. Given the relative newness of these cars, many will still be covered by the BMW warranty, but it is still important to understand the regular maintenance requirements to ensure longevity and peak performance.
This maintenance guide outlines the recommended servicing intervals, key maintenance tasks, and other important considerations for owners of the BMW M8 (including the M8 Competition), based on the official BMW service schedule.
BMW M8 Service Intervals
BMW recommends a structured maintenance schedule to ensure the M8 stays in optimal condition. The intervals below are based on both mileage and time, whichever comes first. Always refer to your specific car’s service book or consult with your BMW dealer for more accurate, model-specific information.
Oil Service: Every 10,000 Miles (16,000 km) or 12 Months
The oil service is one of the most important aspects of regular maintenance. Fresh oil ensures the engine runs smoothly, particularly in a high-performance vehicle like the M8. BMW recommends an oil change every 10,000 miles (16,000 km) or every 12 months, whichever comes first. If the car is used for high-performance driving, or frequently on track, more frequent oil changes may be required.

Inspection Service: Every 20,000 Miles (32,000 km) or 24 Months
The inspection service checks a wide range of components for wear and tear, including brakes, suspension, exhaust, and drive systems. It also covers fluid levels, filters, and diagnostics for any potential issues with the engine and transmission. This service is usually scheduled every 20,000 miles (32,000 km) or every two years. This is an important service to ensure that the M8 remains in top condition, especially given the strain performance driving can put on the vehicle’s systems.
Brake Fluid: Every 2 Years
Brake fluid is critical to maintaining braking performance. Over time, brake fluid can absorb moisture, which reduces its effectiveness and may lead to brake system failure. BMW recommends replacing the brake fluid every two years, regardless of mileage. For owners of an M8, especially those who may drive the car aggressively or track it, ensuring the brake fluid is replaced at the correct intervals is essential for both safety and performance.
Spark Plugs: Every 60,000 Miles (96,000 km)
Spark plugs play a key role in engine efficiency, and their condition directly affects fuel efficiency and engine performance. BMW recommends replacing the spark plugs every 60,000 miles (96,000 km). However, if you notice engine misfires, rough idling, or poor fuel economy before this interval, it's worth getting them checked sooner.

Air Filters: Every 30,000 Miles (48,000 km)
The M8’s engine benefits from a clean air supply, and the air filters should be replaced every 30,000 miles (48,000 km). If the vehicle is frequently driven in dusty or polluted environments, more frequent air filter replacements may be necessary. Clogged or dirty air filters can negatively affect engine performance and fuel efficiency.

Coolant: Every 4 Years
Coolant helps to regulate the engine’s temperature and prevent overheating. BMW recommends changing the coolant every 4 years to ensure that it remains effective in maintaining engine temperature and protecting against corrosion. If you notice that the engine temperature is fluctuating or overheating, it’s important to check the coolant levels and system for leaks.
Extended Warranty Options
As the M8 is a high-performance vehicle, ensuring comprehensive coverage is important. Most M8s will still be covered by the standard BMW warranty, which typically lasts for 3 years or 60,000 miles (96,000 km), whichever comes first. However, if you’re purchasing a used M8 or approaching the end of the standard warranty, you may want to consider purchasing an extended warranty through BMW.
An extended warranty can help mitigate the costs of repairs and parts replacements, particularly as the vehicle ages and more extensive repairs may become necessary. The BMW extended warranty covers many major components, including the engine, drivetrain, and electrical systems, giving owners peace of mind.
Additional Maintenance Considerations for High-Performance Driving
The M8 is a high-performance machine, and as such, it is often driven harder than the average car. For owners who drive their M8 aggressively, participate in track days, or drive frequently in high-performance conditions, extra care and maintenance may be required.
Suspension and Handling
Due to the high weight and performance orientation of the M8, the suspension system is a critical component that requires regular attention. If the car is driven hard, the suspension may experience more wear than usual. It’s important to have the suspension system checked regularly, especially the shocks, springs, and bushings.
Brakes
The M8, especially the Competition variant, comes equipped with high-performance braking systems that are crucial for effective stopping power. Owners should check the brake pads and discs at regular intervals, especially if the car has been driven hard or used on track. The braking components may need to be replaced more frequently under these conditions.
Tyre Maintenance
High-performance tyres will wear more quickly under aggressive driving. It is recommended to inspect the tyres frequently for uneven wear, particularly on the inner edges. Regular alignment checks and tyre rotations can help maintain tyre health and ensure optimal handling performance.
Conclusion
Maintaining a BMW M8 or M8 Competition is essential for ensuring that the car continues to perform at the highest level. While these vehicles are relatively new and many will still be under the BMW warranty, regular servicing and maintenance are important to keep the vehicle running smoothly and reliably. By following the BMW service schedule and paying attention to the vehicle’s performance, you can ensure that your M8 remains in top condition, whether you’re using it for daily driving or high-performance activities. Regular maintenance will also help protect the resale value of your car, ensuring it remains an excellent investment for years to come.
