2025-10-14

If you own a 2022 Mercedes GLC 300, understanding the role of your oil filter with washer—and how to maintain it—could mean the difference between a smooth-running engine and costly repairs down the line. This critical component works tirelessly to protect your engine from contaminants, and ignoring its condition or using the wrong part can lead to accelerated wear, reduced performance, or even catastrophic failure. In this guide, we’ll break down why the 2022 GLC 300’s oil filter with washer matters, how to identify the correct replacement, step-by-step replacement instructions, common pitfalls to avoid, and long-term maintenance tips to keep your SUV running strong.

Why the 2022 Mercedes GLC 300 Oil Filter with Washer Is Non-Negotiable

Modern engines like the GLC 300’s 2.0L turbocharged inline-4 (M264) operate under extreme pressure and heat. Engine oil lubricates moving parts, but it also picks up tiny metal shavings, dirt, soot, and other debris as it circulates. The oil filter’s job is to trap these contaminants before they reach critical components like bearings, camshafts, and pistons. Meanwhile, the rubber or silicone washer (often called an O-ring or gasket) seals the filter to the engine block, preventing oil leaks and ensuring proper pressure retention.

In the GLC 300, Mercedes engineers designed this system with precision. The oil filter isn’t just a “disposable part”—it’s engineered to work in tandem with the engine’s oiling system, maintaining optimal flow rates and filtration efficiency. A subpar filter or worn washer can compromise this balance, leading to:

  • ​Reduced engine life: Contaminants circulating in oil scratch and score bearing surfaces.

  • ​Sludge buildup: Clogged filters force oil to bypass filtration, allowing debris to accumulate.

  • ​Oil leaks: A degraded washer can’t seal properly, causing oil to seep onto hot engine parts (risking fires) or low oil levels (leading to overheating).

  • ​Check Engine Light (CEL) activation: Some GLC 300s have sensors monitoring oil pressure; a failing filter may trigger warnings.

Identifying the Correct 2022 GLC 300 Oil Filter with Washer: OEM vs. Aftermarket

Mercedes-Benz specifies exact part numbers for its components to ensure compatibility and performance. For the 2022 GLC 300, the factory oil filter is typically ​MB Part Number 114 915 00 00, though regional variations (e.g., U.S. vs. European spec) may require double-checking with your VIN. The washer is often included with the filter in OEM kits but may be sold separately as a “filter gasket” (MB Part Number N 108 220 02).

OEM vs. High-Quality Aftermarket Options

While Mercedes recommends OEM parts, reputable aftermarket brands like Mann-Filter, Mahle, Bosch, and Hengst produce filters that meet or exceed factory specs. Here’s how to evaluate them:

  • ​Micron rating: The GLC 300’s engine requires fine filtration—look for filters with a 20-30 micron rating to trap small particles without restricting flow.

  • ​Material quality: Steel or aluminum housings resist corrosion; synthetic media (vs. paper) lasts longer and handles high temperatures better.

  • ​Seal design: Aftermarket washers should match the OEM’s thickness and material (usually nitrile rubber) to prevent leaks.

Avoid no-name brands or “universal fit” filters—they often use thinner metal, lower-quality media, or ill-fitting gaskets that fail prematurely.

Step-by-Step: Replacing the 2022 GLC 300 Oil Filter with Washer

Changing the oil filter and washer on your GLC 300 is a manageable DIY task if you have the right tools and follow safety protocols. Here’s how to do it correctly:

Tools & Materials Needed

  • New OEM or high-quality aftermarket oil filter (MB 114 915 00 00 or equivalent).

  • New washer (MB N 108 220 02 or OEM-spec).

  • Socket wrench set (including a 36mm socket for the drain plug).

  • Oil drain pan (capacity ≥6 quarts).

  • Funnel.

  • Gloves and safety glasses.

  • Jack and jack stands (or ramps) to lift the vehicle.

  • Mercedes-approved 0W-20 synthetic oil (5.5-6 quarts for the GLC 300).

Step 1: Warm Up the Engine

Drive the GLC for 10-15 minutes to warm the oil—this thins it, making it easier to drain completely. Park on a flat surface, engage the parking brake, and let the engine cool for 10 minutes (hot oil burns!).

Step 2: Lift the Vehicle and Remove the Oil Drain Plug

Use a jack to lift the front of the GLC, secure it with jack stands, and chock the rear wheels. Locate the oil pan (under the engine, near the front). Place the drain pan beneath it, then use the 36mm socket to loosen the drain plug. Once loose, finish unscrewing by hand—oil will start flowing immediately. Let it drain for 15-20 minutes until only drips remain.

Step 3: Remove the Old Oil Filter

The GLC 300’s oil filter is mounted vertically on the engine block, near the front (driver’s side). Use an oil filter wrench (strap or cap-style) to grip it—avoid using a wrench that crushes the housing. Twist counterclockwise to loosen; once it’s free, lower it into the drain pan (remaining oil will spill). Inspect the old filter: if the housing is rusted, the gasket is stuck, or the media looks clogged, it’s a sign you needed to replace it sooner.

Step 4: Clean the Filter Mounting Surface and Install the New Washer

Wipe the engine block where the filter mounts with a clean rag—remove all old gasket material. Check for leftover washer fragments (a common cause of leaks); if any remain, use a plastic scraper (not metal) to gently dislodge them. Install the new washer onto the new filter—hand-tighten it first to ensure it seats properly.

Step 5: Install the New Oil Filter

Apply a thin layer of fresh 0W-20 oil to the new filter’s gasket—this helps it seal and makes future removal easier. Screw the filter onto the mounting surface by hand until the gasket contacts the block, then tighten an additional ¾ to 1 full turn. Do not overtighten—this can damage the filter or gasket, leading to leaks.

Step 6: Reinstall the Drain Plug and Refill Oil

Clean the drain plug and its threads, then reinstall it with a new crush washer (Mercedes recommends replacing this annually). Tighten to 25 Nm (18 ft-lbs) with a torque wrench. Lower the vehicle, then remove the oil filler cap (on top of the engine) and add 5.5 quarts of 0W-20 oil. Wait 2 minutes, then check the dipstick—add more oil until it reaches the “MAX” mark (typically 6 quarts total).

Step 7: Start the Engine and Check for Leaks

Start the GLC, let it idle for 2 minutes, then shut it off. Check the drain plug and filter for leaks—wipe them clean, then recheck after 5 minutes. Top off oil if needed (some settling occurs). Finally, reset the oil change indicator via the infotainment system (Settings > Maintenance > Oil Change).

Common Mistakes to Avoid with Your 2022 GLC 300 Oil Filter

Even experienced DIYers make errors with oil filters—here are the most damaging:

  • ​Reusing the old washer: Rubber gaskets degrade over time; always install a new one.

  • ​Over-tightening the filter: This can warp the housing, causing it to leak or crack.

  • ​Ignoring the drain plug crush washer: A worn washer lets oil seep out, leading to low levels.

  • ​Using the wrong oil viscosity: The GLC 300 requires 0W-20—thicker oils strain the filter and reduce fuel efficiency.

  • ​Skipping the drain time: Rushing the drain leaves old oil in the pan, diluting the new oil and reducing its effectiveness.

How Often Should You Replace the 2022 GLC 300 Oil Filter?

Mercedes-Benz recommends changing the oil and filter every 10,000 miles or 12 months under normal driving conditions. However, adjust this based on your usage:

  • ​Severe service: If you frequently tow, drive in stop-and-go traffic, or in extreme heat/cold, replace every 5,000-7,500 miles.

  • ​Off-roading or dusty environments: Contaminants enter the engine faster—check oil levels monthly and replace the filter every 7,500 miles.

Signs you need an early replacement include dark, gritty oil (when checking with the dipstick), whining noises from the engine, or a drop in fuel efficiency.

What Happens If You Delay Oil Filter Replacement?

Neglecting the oil filter accelerates engine wear in several ways:

  • ​Increased friction: Contaminants act like sandpaper on bearings and pistons, leading to premature failure.

  • ​Sludge formation: Over time, trapped debris mixes with oil to form thick sludge, clogging oil passages and reducing lubrication.

  • ​Overheating: A clogged filter forces the oil pump to work harder, generating excess heat that can warp engine parts.

  • ​Expensive repairs: Replacing a damaged engine or turbocharger (common in turbocharged GLCs) costs thousands—far more than regular filter changes.

Where to Buy Genuine 2022 GLC 300 Oil Filters and Washers

To ensure you’re getting a quality part, purchase from:

  • ​Mercedes-Benz dealerships: Guaranteed OEM parts, but prices are higher.

  • ​Authorized online retailers: Sites like FCP Euro or ECS Tuning sell genuine Mercedes parts with warranties.

  • ​Reputable auto parts stores: Stores like NAPA or AutoZone carry Mann-Filter or Mahle filters that meet OEM specs.

Avoid eBay or Amazon marketplace sellers with no reviews—counterfeit filters are common, with thin housings and poor seals that fail quickly.
