BMW M135i / M235i / M140i / M240i Oil Service – Pinnacle Tuning (In-House Only)
At Pinnacle Tuning, we provide specialist oil servicing for BMW M135i, M235i, M140i and M240i models. These vehicles use the N55 and B58 engines, and regular oil servicing is essential to maintain engine performance and long-term reliability — particularly on tuned or hard-driven vehicles.
BMW service intervals are often quite long, however for engine longevity we recommend more frequent oil changes, especially on tuned vehicles. For tuned cars or vehicles driven hard, we typically recommend an engine oil service every 5,000–6,000 miles.
Regular oil servicing helps protect the turbocharger, reduce engine wear, maintain proper oil pressure and cooling, and keep tuned vehicles running safely and reliably.
Our Oil Service includes:
- Engine oil (correct BMW specification oil)
- Oil filter replacement
- New sump plug / washer where applicable
- Vehicle health check and visual inspection
- Diagnostic scan and fault code check
- Service light reset
Pinnacle Tuning is also a BMW approved garage, which means we can update your official BMW online service records (iDrive service history) after your service, keeping your digital service history fully up to date — important for vehicle value and resale.
This service is available in-house only at Pinnacle Tuning and is ideal for customers having tuning, maintenance, or other work carried out with us.
Whether your vehicle is standard or tuned, regular oil servicing is one of the most important things you can do to maintain the N55 and B58 engines and ensure long-term reliability.
