2023 Mercedes-Benz Metris — Oil Capacity & Filter Specs

The 2023 Mercedes-Benz Metris takes about 7.0 liters (7.4 quarts) of engine oil with a new filter.

Quick answer

• Capacity (with filter): 7.0 L (7.4 qt)
• Recommended viscosity: 0W-40 or 5W-40, depending on climate
• Required oil specification: Mercedes-Benz 229.5 (fully synthetic). Oils carrying MB 229.5 approval are required; do not substitute lesser specs.
• Oil filter: OEM Mercedes-Benz A 270 180 01 09 (supersedes A 270 180 00 09). Popular aftermarket cross‑refs: Fram CH11794; WIX 57341 (verify by VIN/application before purchase).

Capacity by engine option

Oil change interval

• Normal service: Up to 15,000 miles or 1 year (whichever comes first), per Mercedes-Benz ASSYST/service schedule when using MB 229.5-approved oil.
• Severe service (frequent idling, stop-and-go, heavy loads, extreme temps, dusty conditions, short trips): 7,500 miles or 6 months. Always follow the instrument cluster service reminder if it calls for earlier service.

Drain plug torque

• Drain plug torque: 30 Nm (22 lb-ft)
• Crush washer: 14 mm aluminum sealing washer; replace at every oil change to prevent seepage. If uncertain on part number for your pan/plug, consult a Mercedes-Benz dealer with your VIN.

How to change the oil

1. Warm the engine to operating temp, then shut off and allow to cool a few minutes.
2. Remove the lower engine cover/undertray for access.
3. Place a drain pan, remove the drain plug, and drain the oil completely. Replace the aluminum crush washer and torque the plug to 30 Nm.
4. Replace the cartridge filter element (top-side housing). Swap both O-rings on the cap, lightly oil them, and seat them in the correct grooves. Install the new element into the housing.
5. Refit the filter cap and torque to the spec molded on the cap (commonly 25 Nm on MB plastic housings—verify on your cap).
6. Fill 6.5 L of MB 229.5-approved 0W-40/5W-40, then start the engine and check for leaks.
7. Shut down, wait a couple of minutes, check level, and top up to about 7.0 L total. Do not overfill—aim for mid-to-upper range on the dipstick/electronic level.
8. Reinstall the undertray, reset the service indicator (ASSYST) via the steering wheel/menu procedure, and properly dispose of used oil and filter.

Common issues / tips for this generation (W447 Metris)

• Use the correct oil spec: The M274 is sensitive to oil quality. Stick to MB 229.5-approved oils; this helps protect the turbocharger and timing chain.
• Filter cap and O-rings: Misplaced O-rings on the cartridge cap cause pressure loss and leaks. Lightly oil the new O-rings and torque the cap to the value printed on the cap (over-torquing can crack it).
• Oil cooler and cam cover seepage: With mileage, small leaks can develop around the oil cooler seals or cam/valve cover. Inspect during oil changes.
• PCV/air-oil separator issues: Rough idle or oil consumption can be related to the breather system; inspect hoses and check valves.
• Charge pipe/clamps: If you notice oil mist around intercooler/charge hoses, check clamps and seals—common on turbo vans.
• Underbody panels: Always reinstall the undertray properly; missing fasteners can lead to rattles and drag.
• Top-off strategy: The system responds slowly to top-offs. Sneak up on the final level after a brief drive and re-check warm.
