2022 Mercedes GLC 300 Oil Filter with Washer: A Complete Guide
Replacing the oil filter and washer on your 2022 Mercedes GLC 300 is a critical maintenance task that requires genuine or high-quality alternative parts, specifically a cartridge-style oil filter and a new crush washer, to ensure optimal engine performance and longevity. Using the correct oil filter with washer and following proper installation procedures will protect your engine from contaminants and prevent oil leaks, making this a straightforward DIY job for most owners.
Understanding Your GLC 300's Oil Filter System
The 2022 Mercedes GLC 300 uses a cartridge-type oil filter rather than a traditional spin-on canister filter. This system consists of a replaceable filter insert that fits into a permanent housing mounted on the engine. When you purchase an oil filter kit for your GLC 300, it should include both the filter cartridge and the necessary sealing rings, typically consisting of multiple gaskets that prevent leaks between the filter housing and engine block.
This design is common in modern Mercedes-Benz engines and requires a different replacement approach than older filter types. The cartridge system is environmentally friendly since it generates less waste than conventional canister filters. However, it does require careful attention to gasket placement and proper tightening torque to prevent oil leaks. Most filter kits for the 2022 GLC 300 include all necessary components: the filter cartridge itself, housing seal, and sometimes a new drain plug crush washer, though the crush washer may need to be purchased separately depending on the kit.
Mercedes recommends changing your oil filter with every oil change, which typically occurs every 7,500 to 10,000 miles under normal driving conditions. However, if you frequently drive in severe conditions such as extreme temperatures, dusty environments, or primarily short trips where the engine doesn't reach optimal operating temperature, you should consider more frequent filter changes. The oil filter plays a crucial role in protecting your engine by capturing contaminants and particles that can cause premature wear to engine components. A clogged or dirty filter can lead to reduced oil flow, increased engine wear, and potentially serious engine damage over time. 1,5
Choosing the Right Oil Filter for Your 2022 GLC 300
Selecting the proper oil filter for your 2022 GLC 300 is essential for maintaining engine health and performance. The genuine Mercedes-Benz oil filter (part number 276-180-00-09) is specifically designed for your vehicle and guarantees perfect fitment and filtration efficiency. However, several aftermarket manufacturers produce high-quality filters that meet or exceed OEM specifications at a lower cost.
Preferred aftermarket brands include Mann, Mahle, Bosch, and Hengst, all of which have excellent reputations for filtration quality and reliability. These manufacturers produce filters with the correct specifications for the 2022 GLC 300's 2.0L turbocharged engine. When selecting an aftermarket filter, ensure it carries the correct OEM approval numbers and matches the specifications of the genuine Mercedes part.
The 2022 GLC 300 requires a filter with specific dimensions and flow characteristics. Typical filter measurements include a height of approximately 86-115mm, an inner diameter of 31-32mm, and an outer diameter of 64-72mm. These specifications ensure proper fitment within the filter housing and optimal oil flow through the filtration media. High-quality filters use synthetic media materials that provide superior contaminant capture while maintaining consistent oil flow, even in extreme operating conditions. 12,13,14,15
Price points for GLC 300 oil filters vary, with genuine Mercedes filters typically costing between 25-30, while quality aftermarket options range from 8-20. While it may be tempting to choose the least expensive option, remember that the oil filter is a critical component for engine protection. Investing in a high-quality filter can prevent costly engine repairs down the road. Many aftermarket filters offer excellent value, providing filtration efficiency comparable to genuine Mercedes filters at a lower price point.
The Importance of the Crush Washer
The crush washer, though small and inexpensive, plays a vital role in your GLC 300's oil system. This specially designed washer creates a perfect seal between the oil drain plug and the oil pan, preventing leaks that could lead to low oil levels and potential engine damage. Made from soft metal such as aluminum or copper, the crush washer is designed to deform slightly when tightened, filling any microscopic imperfections between the drain plug and oil pan surfaces.
It is crucial to replace the crush washer every time you change your oil. Reusing an old crush washer is a common mistake that often leads to leaks. Once compressed during installation, the washer loses its ability to create a proper seal when reused. A leaking drain plug can result in oil loss, which may go unnoticed until engine damage occurs. For the 2022 GLC 300, the drain plug typically requires a 13mm socket, and the crush washer should match the diameter of your vehicle's specific drain plug.
Most quality oil filter kits include a new crush washer, but if yours doesn't, they can be purchased separately from Mercedes dealerships or automotive parts stores. When installing the new washer, ensure it sits flush on the drain plug before reinserting it into the oil pan. Proper tightening is essential—over-tightening can damage the threads in the aluminum oil pan, while under-tightening may not create a sufficient seal. Mercedes typically recommends tightening the drain plug to 25 Nm (18 lb-ft), but always consult your owner's manual for the exact specification for your model year. 1,2
Step-by-Step Replacement Guide
Replacing the oil filter and washer on your 2022 GLC 300 is a straightforward process that most DIY enthusiasts can complete in about an hour. Before beginning, gather all necessary tools and materials: a high-quality oil filter kit, a new crush washer, the correct amount and type of synthetic oil (6.3 quarts of 0W-20 synthetic meeting MB 229.71 specification), an oil drain pan, a 27mm socket wrench for the filter housing, a 13mm socket or wrench for the drain plug, a flathead screwdriver for removing protective covers, and gloves.
Start by warming up the engine briefly to thin the oil for better drainage, but ensure it's not too hot to avoid burns. Park on a level surface and engage the parking brake. Begin by removing the plastic skid plate underneath the engine, which is typically secured by four 8mm screws at the front and another four at the rear. Position your drain pan beneath the oil drain plug, then use your 13mm wrench to loosen the plug. Once loose, carefully remove it by hand, being prepared for the initial rush of oil. Allow the oil to drain completely, which may take 10-15 minutes.
While the oil drains, move to the oil filter housing located on the top of the engine. You may need to remove a plastic engine cover, which typically clips off or requires a flathead screwdriver to release retaining clips. Use your 27mm socket to loosen the bolt on top of the filter housing. Once loose, carefully remove the housing assembly—some residual oil may spill out, so have your drain pan or rags ready. Remove the old filter cartridge and carefully clean the housing interior. Replace all seals with the new ones provided in your filter kit, lubricating them with a small amount of fresh oil to ensure proper sealing.
Install the new filter cartridge into the housing, reassemble the unit, and tighten the housing bolt to specification (typically 25 Nm or 18 lb-ft). Reinstall the engine cover if removed. Return underneath the vehicle to reinstall the drain plug with its new crush washer, tightening to the specified torque. Replace the skid plate and lower the vehicle. Add new synthetic oil through the filler cap under the hood, using a funnel to avoid spills. Start with approximately 5.5 quarts, then check the level with the dipstick, adding more gradually until reaching the proper level.
Start the engine and let it run for a minute, then check for leaks around both the drain plug and filter housing. Turn off the engine, wait a minute for oil to settle, then recheck the level and add more if necessary. Properly dispose of the used oil and filter at a certified recycling center—most auto parts stores accept these materials at no charge. 1,4,6,7
Common Mistakes to Avoid
When changing the oil filter on your 2022 GLC 300, several common errors can lead to problems down the road. Failing to replace all seals is perhaps the most frequent mistake. Your filter kit should include new gaskets for the filter housing, and skipping replacement of any of these seals can result in oil leaks. Similarly, forgetting to install a new crush washer on the drain plug often leads to slow leaks that may go unnoticed until oil levels become dangerously low.
Over-tightening components is another common issue. The oil filter housing bolt and drain plug both thread into aluminum components that can be damaged by excessive force. Stripped threads in the oil pan or filter housing can lead to costly repairs. Always use a torque wrench when possible, and follow the manufacturer's specifications precisely. If you don't have a torque wrench, tighten until snug and then add only a slight additional turn—avoid using excessive force.
Some DIYers make the mistake of installing the filter cartridge incorrectly. Ensure the old gasket is completely removed from the housing before installing the new filter, as double-gasketing can cause significant leaks. Also, make sure the filter is properly seated in the housing before reassembly. Another error is using the wrong type of oil—your 2022 GLC 300 requires full synthetic oil meeting MB 229.71 specifications, typically 0W-20 weight. Using conventional oil or the wrong viscosity can affect engine performance and longevity.
Finally, failing to properly reset the maintenance indicator after completing the service is an oversight many owners make. Your GLC 300 has an intelligent maintenance system that tracks service intervals. After changing the oil and filter, navigate through your vehicle's COMAND system to reset the service indicator, ensuring accurate tracking until your next scheduled maintenance. 1,5
Troubleshooting and Maintenance Tips
After replacing your GLC 300's oil filter and washer, monitor your vehicle for any signs of problems. If you notice oil spots under your vehicle after the change, likely sources are the drain plug or filter housing. Verify that both are properly sealed and that you installed new gaskets and washers. If leaks persist, you may need to replace the components again, ensuring all surfaces are clean and free of debris before installation.
An oil pressure warning light after an oil change indicates a serious issue that requires immediate attention. This could signal a clogged oil filter, though it's more likely that oil levels are too low, there's an obstruction in the oil system, or the oil pressure sensor was damaged during service. First, check your oil level and top up if necessary. If the light persists, have your vehicle inspected by a professional to prevent potential engine damage.
For optimal performance, check your oil level regularly—at least once a month or before long trips. The 2022 GLC 300 features an electronic oil level sensor accessible through your infotainment system, but it's still wise to periodically verify levels using the traditional dipstick. Note that oil consumption may increase slightly after switching to a new filter, as the fresh filter media initially absorbs some oil.
Keep records of your oil changes, including date, mileage, oil type and quantity, and filter brand. This documentation is valuable for warranty purposes and future maintenance. If you plan to perform extended oil change intervals beyond Mercedes' recommended 10,000 miles, consider using oil analysis services to monitor engine health and determine the optimal change interval for your specific driving conditions. 1,5

If you encounter unexpected difficulties during the process, such as a stuck drain plug or filter housing bolt, it's best to consult a professional rather than risk damaging components. Similarly, if you complete the oil change but notice unusual engine noises, warning lights, or performance issues afterward, have a qualified technician inspect your vehicle.
Mercedes-Benz dealerships and specialized independent shops offer Service A and Service B packages that include oil and filter changes along with comprehensive vehicle inspections. These services may be worthwhile if you prefer having trained technicians handle your maintenance or if your vehicle is still under warranty. Professional service ensures that all maintenance records are properly documented, which helps maintain your vehicle's resale value.
Even if you typically perform your own maintenance, consider having a professional oil change periodically to ensure that your vehicle receives the thorough inspection that accompanies dealer service. Technicians can identify potential issues before they become major problems, potentially saving you money in the long run. This is particularly important as your vehicle ages and accumulates mileage. 1
