Mercedes-Benz M274 2.0T 4 cylinder Engine Oil Change
Reviewed/Verified by:
The specification matters more than the viscosity on these engines. Mercedes calls for oil meeting MB 229.5 or higher, and within that you can run 0W-30, 0W-40, 5W-30 or 5W-40 depending on climate. The M274 and M270 turbo four is fitted to a long list of 2013 and later models including the C, E, GLK, GLC and SLK, plus several Infinitis, so check the capacity for your own engine rather than going by the badge.
At a Glance
- Fits: Mercedes M274 and M270 2.0 liter turbo four cylinder engines, also used in some Infiniti models.
- Oil: a Mercedes approved oil meeting MB 229.5, in the viscosity your manual allows.
- Filter: cartridge type at the front of the engine, removed with a 27mm socket; replace the O rings with the filter.
- Fill, run the engine, then check the level on the dipstick or in the instrument cluster.
- Reset the service indicator afterward so the next reminder is correct.

Place the vehicle in Park. Secure the vehicle with jack stands.
Place wheel chocks behind the rear wheels to prevent the vehicle from rolling.
Remove eight 8mm screws from the splash shield.
Carefully lower the splash shield to access the engine oil pan.
Some models have the oil pan further toward the back and the drain plug on the passenger side. Removing the rear splash shield will be needed if that is the case. This will expose the engine oil pan and also the drain bolt. Don’t remove the bolt from the last pan, the transmission pan.
Slide the oil container under the oil pan. Remove the oil drain bolt. Allow engine oil to drain fully, which can take up to 10 minutes. 
Pull the hood release under the dashboard to open the hood.
Pull up the engine cover. There are no screws to remove.
Remove the air intake pipe.
Twist the small plastic screw to get it loose but not remove it.
Locate the engine oil filter at the front of the engine.
Remove the oil filter using a 27mm socket. 
Replace the filter and the O-rings. 
Twist the filter slightly to remove it. Be careful not to break the filter housing.
Reinstall the oil filter and torque it in two stages. The first stage is 25Nm, and the second stage is 30Nm.
Reinstall the drain plug and torque it to 30 N.m (22 lb. ft). Remember to replace the washer with the drain plug.
Remove the engine oil cap and add 6.5 quarts of engine oil.
Remove the oil dipstick and check the engine oil level. Add engine oil as needed.
Check the engine oil level using the dipstick. Add engine oil to bring the level to the middle of the Max and Min marks.
Notes on using a fluid extractor
- You may prefer to use an oil extraction pump instead of jacking up the car to drain the oil.
- If you decide to go this route, you will not need ramps, a drain pan, or 8mm or 13mm sockets.
- You will need an oil extraction pump such as a Mityvac Fluid Evacuator or OEM Tools Fluid Extractor.
- You will use the oil dipstick to drain the oil instead of the drain plug.
- A small amount of old oil (5%-10%) may remain in the oil pain when using a fluid extractor.

Use an oil carrying the correct MB approval
This matters more on a Mercedes than on most cars, and the viscosity grade on the front of the bottle is not the part that counts. Mercedes approves oils against its own specification sheets, and the approval number is what you match. For this engine that is typically MB approval 229.5, with 229.51 and 229.52 being the lower ash specifications required where a particulate filter is fitted.
The approval number is printed on the back of the bottle and listed on the manufacturer’s website, and the requirement for your specific car is in the owner’s manual and usually on the oil filler cap. A 0W-40 or 5W-30 that does not carry the right MB number is not a substitute, however reputable the brand, because the approval covers the additive package and ash content rather than just how the oil flows.
Getting this wrong on a turbocharged direct injection engine is a slow and expensive mistake rather than an immediate one. The wrong additive package accelerates timing chain wear and, on particulate filter equipped cars, clogs the filter with ash that cannot be burned off.
Two things worth doing while you are under there
Always fit a new sealing washer on the drain plug rather than reusing the old one, and replace the O rings supplied with the filter rather than reusing those either. A reused crush washer is the most common cause of a drain plug that weeps afterwards, and people usually respond by overtightening it, which strips the thread in the aluminum sump and turns a service into a sump replacement. The torque figure quoted above exists for that reason, so use a torque wrench.
While the undertray is off, look at the engine for leaks now that you have the access. Oil weeping from the filter housing gasket, the valve cover or the turbo oil feed lines is easy to spot with the car raised and lit, and far easier to deal with early.
Reset the service reminder and check the level properly
As the article notes, ASSYST PLUS tracks the service interval, and it needs resetting after the work rather than being left to count down from the old service. Resetting it without doing the work also leaves a false service record against the car, which a dealer or buyer will see later.
Check the oil level the way the car expects. Many of these models have no conventional dipstick and use an electronic reading instead, which requires the engine at operating temperature and the car parked level, with the reading taken through the instrument cluster menu. Taking it cold or on a slope gives a misleading figure, and overfilling a turbocharged engine is harmful in its own right because the crankshaft whips the excess into foam, which does not carry pressure. A full system scanner that supports Mercedes can perform the service reset and read the oil level and temperature directly, which is quicker than working through the cluster menus.
Frequently Asked Questions
What’s the difference between M270 and M274?
The M270 is transversely mounted, while the M274 is a longitudinally mounted engine. Regardless of how the engine is mounted on your vehicle, instructions on changing the engine oil remain the same.
Can I use an oil extractor to change the engine oil?
Yes. Many owners use an oil extractor pump such as the Mityvac Fluid Evacuator. An oil extractor makes the job easier, but keep in mind a small amount of old oil will remain in the oil pan.
When Should car engine oil be changed?
Approximately every 10,000 miles, depending on the oil you use. Also, some say you can change oil around 5,000 to 7,500 miles.
