2018 Mercedes-Benz Metris — Oil Capacity & Filter

The 2018 Mercedes-Benz Metris 2.0L turbo (M274) takes approximately 7.4 quarts (7.0 liters) of engine oil when replacing the filter.

Quick answer

• Oil capacity (with filter): ~7.4 qt (7.0 L)
• Recommended viscosity: SAE 0W-40 or 5W-40 (climate-dependent)
• Required oil specification: Mercedes-Benz MB 229.5 (or MB 229.51/229.71 where applicable); always choose oil that explicitly lists an MB 229.x approval
• Oil filter: OEM Mercedes element A 270 180 00 09 (verify supersession by VIN). Popular aftermarket equivalents include Mann-Filter HU 718/5 x and Mahle OX 388D. Fram, Wix, and Mobil 1 offer compatible elements—confirm the exact part number in their catalogs using your VIN.

Capacity by engine option

Oil change interval

• Normal service: Up to 15,000 miles (24,000 km) or 1 year, as indicated by the on-board ASSYST service reminder, when using oil that meets MB 229.5/229.51/229.71.
• Severe service (short trips, heavy idling, dusty conditions, frequent towing or high-load use): 5,000–7,500 miles (8,000–12,000 km) or 6 months. Shorter intervals help minimize deposits in this turbocharged, direct-injected engine.

Tip: Always follow the vehicle’s service indicator; it accounts for operating conditions. If time and mileage conflict, service at the earlier of the two.

Drain plug torque

• Drain plug torque: 30 Nm (22 lb-ft)
• Crush washer: Replace the aluminum sealing washer every service to prevent seepage.

How to change the oil

1. Warm the engine to operating temp, then switch off. Raise and support the vehicle safely; remove the lower undertray (Torx fasteners) for access.
2. Place a drain pan, remove the drain plug, and allow oil to drain fully. Install a new crush washer and torque the plug to 30 Nm (22 lb-ft).
3. At the cartridge oil filter housing, remove the cap (use the correct socket) and extract the old element. Replace the large O-ring on the cap, lightly lubricate with fresh oil, and install the new filter element fully seated.
4. Refit and tighten the filter cap to the housing’s specified torque (consult service data for your housing; do not overtighten).
5. Fill the engine with ~6.5–7.0 qt (6.2–6.6 L), then start the engine for 30 seconds to fill the filter. Shut down, wait 5 minutes, and top off to the final level (do not exceed the full mark). Total fill is about 7.4 qt (7.0 L).
6. Reinstall the undertray. Reset the ASSYST service reminder through the instrument cluster per the owner’s manual.
7. Check for leaks after a short test drive and recheck the oil level.

Common issues / tips for this generation (W447 Metris)

• Use an MB-approved oil: Turbocharged direct injection (GDI) engines like the M274 benefit from high-detergent, shear-stable European formulas. Oils with MB 229.5 (high SAPS) are widely used in North America for this engine; 229.51/229.71 low-SAPS approvals may be specified in some documentation. Always verify the label lists an actual MB approval number.
• Don’t overfill: Overfilling can aerate oil and trigger level warnings. Sneak up on the final fill and confirm with the dipstick/level check.
• Filter housing O-ring: Lightly oil the new O-ring and be sure it’s in the correct groove. A pinched or dry O-ring is a common cause of leaks after service.
• Oil cooler/filter housing seepage: With age, the housing seals can sweat oil. If you notice oily residue near the housing, inspect and replace seals as needed.
• PCV and intake cleanliness: GDI engines can accumulate intake valve deposits. Quality fuel, periodic spirited highway driving, and timely oil changes help. Some owners opt for intake cleaning around 60–80k miles if symptoms develop.
• Underbody panel fasteners: Keep Torx clips organized to avoid rattles on reassembly.

Parts notes

• OEM oil filter: Mercedes-Benz A 270 180 00 09 (supersessions may apply; confirm by VIN). Reliable aftermarket: Mann HU 718/5 x; Mahle OX 388D. Fram, Wix, and Mobil 1 also catalog elements for the M274—confirm exact part numbers with your VIN before purchase.
• Drain plug/washer: Use the correct-size aluminum crush washer; many kits include the washer with the filter element.
