2020 Mercedes-Benz GLS-Class Oil Filter

Mercedes-Benz GLS-Class Oil Filter service at Park Place Motorcars Arlington in Arlington, TX

Frequently asked questions

The 2020 Mercedes-Benz GLS-Class is a premium all-wheel-drive SUV with a 3.0 to 4.0-liter engine, six to eight cylinders, and required premium unleaded fuel. At Park Place Motorcars Arlington in Arlington, TX, an oil filter service helps keep the engine's lubrication system working as intended. The service includes an engine-matched oil filter, a new drain plug gasket or washer where applicable, and a leak check after the engine has run. Because the filter captures debris carried by the oil, replacing it alongside the oil helps prevent the bypass valve from sending unfiltered oil through the engine. Schedule service when the filter has gone beyond the oil-change interval, the oil darkens quickly after a change, or the engine sounds noisier than usual.

What an oil filter replacement on a 2020 Mercedes-Benz GLS-Class involves

An oil filter replacement begins with a filter matched to the engine's specification. The 2020 Mercedes-Benz GLS-Class is offered across its trims with 3.0 to 4.0-liter engines and six to eight cylinders, so the correct filter is selected for the engine actually fitted to the vehicle. The old filter is removed with the oil service, and the sealing point is renewed with a new drain plug gasket or washer where the engine uses one.

After the new filter and oil are installed, the engine is run so the technician can check the filter seal for leaks. That final inspection helps confirm that the service was completed cleanly before the vehicle returns to the road. Booking the service means the filter is replaced alongside the oil rather than carried into another change. To arrange this work, schedule service at a convenient time.

Why the filter matters on a 2020 Mercedes-Benz GLS-Class

The 2020 Mercedes-Benz GLS-Class uses engines ranging from 3.0 to 4.0 liters and six to eight cylinders across its two trims. As oil circulates through an engine, it carries away particles and other debris. The oil filter holds that material so the oil reaching engine components is cleaner. A filter is a working part of the lubrication system, not just an accessory changed for convenience.

Once the filter loads with debris, its bypass valve opens. That keeps oil moving, but it means the engine is receiving unfiltered oil. A loaded filter does not stop the engine getting oil; it stops the engine getting filtered oil, and that is worse in a quiet way. Replacing the filter with the oil prevents one service's collected debris from remaining in service through the next change. An oil-pressure warning, unusual engine noise, or oil that darkens quickly after a change deserves attention.

Frequently Asked Questions

6 common questions answered

Is the oil filter replaced every time a 2020 Mercedes-Benz GLS-Class has its oil changed?The oil filter should be replaced alongside the oil service when the vehicle is booked for oil and filter service.

The filter collects debris from the oil as it circulates. Carrying the same loaded filter into another oil change can leave the bypass valve sending unfiltered oil through the engine.

  • Filter matched to the fitted engine
  • New drain plug gasket or washer where applicable
  • Leak check after the engine runs
What is included in an oil filter replacement on a 2020 Mercedes-Benz GLS-Class?The service includes an engine-matched filter, a new drain plug gasket or washer where used, and a post-service leak check.

The filter is selected for the engine actually fitted to the SUV. After the oil and filter work is completed, the engine is run so the filter seal can be checked.

  • Filter matched to engine requirements
  • Sealing hardware renewed where applicable
  • Filter seal inspected for leaks
What happens if the oil filter on a 2020 Mercedes-Benz GLS-Class is not replaced?A loaded filter can open its bypass valve, allowing oil to circulate without filtration.

The engine still receives oil, but it does not receive filtered oil. This can quietly reduce the filter's ability to hold debris, which is why the filter is replaced with the oil rather than stretched across two changes.

  • Oil may darken quickly after a change
  • The engine may sound noisier than usual
  • An oil-pressure warning may appear
Does a 2020 Mercedes-Benz GLS-Class need a specific oil filter?Yes, the filter is matched to the engine, and filters are not interchangeable across engines.

This SUV uses a 3.0 to 4.0-liter engine with six to eight cylinders across its trims. The correct filter depends on the engine actually fitted, so selection should be made during service rather than assumed from the vehicle name alone.

  • Engine displacement: 3.0 to 4.0 liters
  • Cylinder count: six to eight
  • Filter selected for the fitted engine
Can the oil be changed on a 2020 Mercedes-Benz GLS-Class without changing the filter?The oil can be changed separately, but oil and filter service replaces the filter at the same time.

Replacing only the oil leaves the existing filter holding the debris it has collected. If the filter loads, its bypass valve opens and unfiltered oil circulates, so the filter is best changed alongside the oil.

  • Filter captures debris carried by oil
  • Loaded filters can open the bypass valve
  • Service includes a leak check after running
