Mercedes-Benz B-Class Maintenance Plans

Petrol Mercedes-Benz B-Class models span several engine families and calibrations, so service requirements can differ by generation. Most schedules include regular engine oil and filter changes, commonly around 10,000-15,000 km or 12 months depending on usage and the service plan shown for your engine. On petrol engines, keep an eye on ignition-related maintenance (such as spark plugs where fitted) and air intake filtration, as these can affect driveability and emissions if neglected. Common petrol engine families across the range include 270, 282 and 266, so always check the selected engine for the exact operations.

Diesel B-Class servicing is often shaped by how the car is used, particularly repeated short trips versus longer runs. Oil and filter changes are a core requirement, with typical schedules in the 10,000-15,000 km and 12-month range shown for this family, but your exact engine selection may specify a different cadence. Diesel-specific items to watch include fuel filtration and emissions-system condition on engines equipped with EGR and DPF, as these can be sensitive to driving style and maintenance history. Diesel engine families seen in the B-Class include 654, 651, 640, 608 and 607, so confirm details against your chosen variant.

48V (MHEV) B-Class models combine a petrol engine with additional electrical hardware, so correct fluids and service procedures matter. The routine servicing still centres on engine oil and filter changes, commonly around 10,000-15,000 km or 12 months in the schedules shown for this family, with the exact interval set by the selected engine and year. Because hybrid-assist systems add extra components, it is especially important to follow the specified checks and not skip inspection items that may be listed alongside the basic service operations. MHEV examples in this range include the 260 engine family, so use the selector to pull the correct plan for your exact model.

CNG-capable B-Class models are typically bi-fuel (CNG and petrol), so maintenance needs can reflect both systems. Keep to the scheduled oil and filter changes shown for your chosen engine and year, and pay attention to any fuel-system checks listed in the plan, as consistent servicing supports smooth changeover and reliable running. If the car spends long periods running on one fuel, it is still worth following the full schedule because components tied to the other fuel system can age with time as well as mileage. CNG examples include NGT variants in the 266 and 270 engine families, so confirm the exact operations for your specific B-Class.

LPG B-Class models are commonly petrol-based with an LPG system added, so servicing typically combines normal petrol-engine maintenance with additional fuel-system checks where specified. Follow the oil and filter intervals shown for your selected engine and generation, commonly around 10,000-15,000 km or 12 months on this family page, and do not ignore inspection items listed in the schedule. Because LPG operation can change combustion conditions, it is particularly important to keep on top of service items that support correct running and emissions control. LPG examples appear across engine families such as 266 and 270, so always confirm the exact plan for your model.
