2022 Mercedes-Benz Metris Oil Capacity, Weight, & Filter Specs

The 2022 Mercedes-Benz Metris takes exactly 6.1 quarts (5.8 liters) of full synthetic oil when replacing the oil and the oil filter. As an ASE-certified master technician, I know that keeping up with the proper maintenance on Mercedes-Benz commercial and passenger vans is critical for the longevity of the turbocharged powertrain. Below, you will find all the exact specifications, filter part numbers, and torque values you need to complete a proper oil service on your Metris.

Quick answer

Here is the essential information you need before heading to the parts counter for your 2022 Mercedes-Benz Metris:

• Total Oil Capacity: 6.1 quarts (5.8 liters) including the filter.
• Recommended Oil Weight: 5W-40 or 0W-40 full synthetic.
• Required Oil Specification: Mercedes-Benz MB 229.5 (or MB 229.51). Using an oil with this specific MB approval on the back of the bottle is mandatory.
• OEM Oil Filter: Mercedes-Benz A 274 180 01 09
• Aftermarket Oil Filters: Mann HU 711/6 z (Mann is the OEM supplier), Wix WL10057, or Fram CH11473.

Capacity by engine option

For the 2022 model year in the North American market, the Metris was only offered with one engine option, the reliable M274 2.0-liter turbocharged inline-4.

Oil change interval

Because the Metris is frequently used for commercial hauling, livery services, and heavy payload transport, adhering to the correct service schedule is crucial.

• Normal Duty: 15,000 miles or 12 months, whichever comes first. (This is the standard Mercedes-Benz Assyst Plus schedule).
• Severe Duty: 7,500 to 10,000 miles or 6 months. If you idle frequently, operate primarily in stop-and-go city traffic, or routinely carry heavy cargo payloads, you should cut the standard interval in half to protect the turbocharger and timing chain components.

Drain plug torque

• Drain Plug Torque: 30 Nm (22 lb-ft).
• Crush Washer Note: You must replace the copper/aluminum crush washer on the drain plug every time it is removed. Reusing the old washer is a guaranteed way to develop a slow oil leak.

How to change the oil

1. Warm up the engine: Run the van for a few minutes to get the oil warm (but not scalding hot) so it drains faster and suspends particulates.
2. Access the drain plug: Safely raise and support the front of the vehicle. Remove the plastic lower engine shield to access the oil pan.
3. Drain the oil: Place a catch pan underneath, remove the 13mm drain plug, and allow the oil to drain completely.
4. Replace the oil filter: While the oil drains, open the hood and locate the top-mount oil filter housing. Use a 27mm socket to unscrew the plastic cap. Remove the old cartridge filter, replace the three rubber O-rings on the cap (lubricate them with fresh oil), and press the new cartridge into the cap. Torque the cap to 25 Nm (18 lb-ft).
5. Reinstall drain plug: Install a new crush washer on the drain plug, thread it in by hand, and torque it to 30 Nm (22 lb-ft). Reinstall the underbody shield.
6. Refill and check: Fill the engine with 6.1 quarts of MB 229.5 approved oil. Start the engine, let it run for 30 seconds, shut it off, and check for leaks. Use the dipstick to verify the final oil level is at the "MAX" mark.

Common issues / tips

• Oil specification matters: Do not just grab any 5W-40 off the shelf. The M274 engine is highly sensitive to oil quality. If the oil does not explicitly say "MB-Approval 229.5" (or 229.51), do not use it.
• Top-mount filter mess: When removing the oil filter cap, unscrew it partially and let it sit for a minute. This allows the oil trapped in the housing to drain down into the oil pan rather than spilling all over the front of the engine block.
• PCV system and oil consumption: The M274 can consume a small amount of oil between long 15k-mile services, especially under heavy commercial use. Keep a spare quart in the van and check the dipstick monthly.
