Mercedes Benz Engine Oil , Air Filter, AC FIlter , Oil Filter Combo Package

Mercedes Benz Engine Oil , Air Filter, AC FIlter , Oil Filter Combo Package.

Part A2561840000

• Type / Function: Engine Oil Filter Element (filter insert) for Mercedes-Benz.
• Other names / OEM numbers: A 256 184 00 00 (sometimes shown as 2561840000)
• Dimensions / Physical Attributes:
• Diameter ~ 54 mm
• Height ~ 201-218 mm depending on manufacturer and variant.
• Inner diameters etc differ slightly depending on brand (see cross references)
• Which engines / vehicles it fits:
  The filter is used in Mercedes-Benz 3.0 L inline-6 mild hybrid & non-hybrid engines, roughly encoded as M256 / inline-6 gasoline types. Some example vehicles include:
• Mercedes-Benz AMG GT 43 (3.0L I6)
• GLE53 AMG, GLS450, S500, CLS450 etc with the 3.0L inline-6 mild hybrid engines.
• Remarks:
• It’s genuine Mercedes-Benz (OEM) part.
• There are many aftermarket replacements with correct dimensions, but care must be taken for correct sealing, pressure rating etc.

Part A6540920100

• Type / Function: Fuel filter kit, specifically for OM654 engines (diesel). Not the engine oil filter; this one is fuel / fuel/water, sometimes activated carbon, etc.
• Which engines / vehicles it fits: OM654 diesel family. Some examples:
• Mercedes E-Class (E200d / E220d) with OM654 engine
• Models with designations like W205, W206, W213 etc in diesel trims.
• Specs / Notes:
• It may include activated carbon filter / particle / water separation etc.
• Has tightly controlled filtration properties (fine particle separation etc) because diesels are sensitive to fuel cleanliness.

Summary / Fitment

If you tell me the model-year and engine type (gasoline/diesel, displacement, etc) of your vehicle, I can confirm whether both of these parts are correct or whether only one applies (or neither). Do you want me to check for your specific car?

Here’s a breakdown of Mercedes engine oil grades (e.g. 5W-30, 0W-20, etc.), what the numbers/specs mean, which Mercedes oil specifications (MB 229.x, etc) are involved, and which vehicles / engines use which. If you give me your exact model and year, I can tell you what your car should use.

What Do the Oil Grades Mean (0W-20, 5W-30, etc.)

Oil grades like 0W-20 or 5W-30 are viscosity ratings defined under SAE standard. They tell how the oil behaves under cold start (the “W” = winter) and at operating temperature.

• The first number + “W” (0W or 5W etc) describes low-temperature (cold start) viscosity. Lower = flows more easily when cold.
• The second number (20, 30, etc) describes high temperature viscosity / how thick the oil remains when operating hot. Higher = thicker film at high temp.

Lower “W” and lower second number generally improve cold starts and fuel efficiency; thicker high-temp oil can better protect under high loads, heat, or older/higher mileage engines.

Mercedes’ Oil Specifications (MB 229.x etc)

Mercedes-Benz uses specific oil standards (“MB approval” or “MB spec”) that go beyond just the viscosity grade. Some of these include:

Mercedes specifies which MB spec and viscosity grade your engine needs. Using the wrong spec or viscosity can lead to poor performance, excessive wear, or even damage (and could affect warranty).

5W-30 vs 0W-20 in Mercedes Context

Here’s how 5W-30 vs 0W-20 compare for Mercedes:

• 0W-20: Thinner at both cold and hot operating temperatures (especially cold). Good for fuel efficiency, reduced friction, quicker oil circulation at startup. Often used in engines designed for that oil, especially newer, lighter engines, hybrids, or ones with low-friction targets. Must use oils meeting the newer low-friction MB specs (e.g. 229.71 / 229.72).
• 5W-30: Slightly thicker at cold compared with 0W, and typically more robust at higher temperature. Many existing Mercedes gasoline and diesel engines (especially those with particle filters, or older models) use 5W-30 in oils meeting MB 229.51 / 229.52 etc. It offers good protection across a wider temperature range, more margin under load or high heat.

So, unless your engine is specifically designed for 0W-20 (MB spec), using a 5W-30 with correct MB spec is safer and more broadly applicable. But using 0W-20 where not approved may have downsides: thinner at high temps could lead to less oil film thickness under heavy load, faster consumption, etc.

Which Vehicles / Engines Use Which Oil Grade

Here are examples of what types of Mercedes engines tend to use which oil:

Things to Check / Be Careful With

• Always check owner’s manual or manufacturer spec sheet for your specific engine. It will tell you the required MB spec, and sometimes the acceptable viscosity grades.
• An oil’s MB approval is very important. Don’t just choose grade; check spec (229.71, 229.52, etc).
• Changing to a lower viscosity oil than specified (e.g. trying 0W-20 on an engine requiring 5W-30) may reduce protection under high heat or load.
• In very cold climates, viscosity at cold (“W” rating) matters a lot for startup / oil flow. In hot climates, high temp viscosity matters more.
