Per-engine engine-oil and coolant capacities for the Mercedes-Benz B-Class (W247, 3rd gen) (2019 – present), read from the manufacturer's owner's manual and cited per value. Oil figures are the service-refill quantity with a new filter; where the generation offers more than one engine the figures differ — match the row to your engine. Fill quantities differ by procedure: a drain-and-fill is usually less than a dry (overhaul) fill — confirm the method in the manual before topping up.

From the manufacturer's workshop / owner documentation for this generation. Gen-wide figures — some values can vary by trim or model year. Fill quantities differ by procedure: a transmission or axle “service” drain-and-fill is often far less than the dry capacity — always confirm the exact fill method in the manual before filling.

Frequently asked
- What is the engine oil capacity of the Mercedes-Benz B-Class (W247, 3rd gen) (2019 – present)?
- Engine oil capacity with a new filter is 6.9 US qt · 6.5 L. This is the service-refill quantity, not the dry/overhaul fill; add most of it, then top up to the dipstick mark and use the viscosity grade listed above. Verified from the manufacturer's documentation and cited.
- What is the coolant capacity of the Mercedes-Benz B-Class (W247, 3rd gen)?
- The total cooling-system capacity (including the heater core and expansion tank) is 10.6 US qt · 10 L. A routine drain-and-fill replaces less than the full system, so bleed the air and re-check the level warm. Use the coolant type specified for this vehicle — mixing incompatible coolants reduces corrosion protection. Verified from the manufacturer's documentation.
- What is the wheel-nut (lug) torque for the Mercedes-Benz B-Class (W247, 3rd gen)?
- Wheel-nut (lug) torque is 130 Nm. Tighten in a diagonal (star) pattern in two or three even stages, on clean, dry threads, and re-check after roughly 80 km (50 miles) of driving — the most common cause of warped brake discs is uneven or over-torqued wheel nuts. Verified from the manufacturer's documentation.
