Tips for Modified F40 128ti Owners
If you’ve modified your car for additional performance, your maintenance requirements might differ slightly. Here are a few recommendations:
1. Increased Oil Change Frequency
For vehicles with performance modifications such as engine remapping or upgraded turbos, consider changing the engine oil every 5,000–7,500 miles (8,000–12,000 km). Enhanced performance can increase engine stress, making fresh oil critical.
2. Monitor Brake Components
If you’ve upgraded the brakes (e.g., larger discs, performance pads), check wear levels more frequently. Performance braking generates more heat, which can accelerate wear. Check out our range of upgraded brakes here
3. Check Tyre Wear and Alignment
Modifications such as lower suspension or wider wheels can affect tyre wear patterns. Perform regular alignment checks and inspect tyre tread depth to maintain safety and performance.
4. Use Quality Fluids
For modified cars, consider using high-performance fluids for the engine, transmission, and brakes. These fluids offer better heat resistance and lubrication, which are essential for higher-stress applications.
5. Pay Attention to Exhaust Systems
If you’ve fitted an aftermarket exhaust or downpipe, inspect for signs of leaks or wear during every service. This ensures optimal performance and compliance with UK road regulations.
General Maintenance Tips for All Owners
- Wash and Protect Regularly: Clean your car, including the underside, to prevent corrosion from road salt, particularly in winter months.
- Battery Health: Ensure the battery is charged and check its condition during routine inspections.
- Software Updates: BMW often releases software updates for better performance or bug fixes. Have your dealership check for updates during service visits.
Conclusion
Following BMW’s service schedule and adapting it to your specific use case, especially if your car is modified, will help your F40 128ti remain reliable and enjoyable to drive. Regular maintenance, combined with careful monitoring of wear and tear, will ensure you get the most out of your vehicle.
