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 with the oil when the applicable maintenance service calls for an oil and filter service.

A fresh filter gives new oil a clean filtering surface. The correct timing depends on the Mercedes-Benz maintenance schedule, service history, and inspection rather than a universal interval.

  • 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 applicable, and a post-run leak check.

The filter is selected for the engine actually fitted to the SUV. After installation, the engine is run so the filter seal can be checked for leaks.

  • Filter matched to the engine specification
  • Renewed sealing washer or gasket when used by the engine
  • Inspection of the filter seal after operation
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 being filtered.

The engine can still receive oil, but it may no longer receive filtered oil. Debris held by the filter can also contribute to a noisier engine or an oil-pressure warning, which should prompt inspection.

  • Bypass valve may open when the filter loads
  • Oil can circulate without normal filtration
  • Warning signs may include noise or an oil-pressure alert
Does a 2020 Mercedes-Benz GLS-Class need a specific oil filter?Yes, the filter is matched to this engine, and filters are not interchangeable across engines.

The 2020 Mercedes-Benz GLS-Class uses either a 3.0-liter six-cylinder engine or a 4.0-liter eight-cylinder engine. The fitted engine determines which filter is appropriate, so the vehicle should be identified by its actual engine configuration.

  • 3.0-liter engine option
  • 4.0-liter engine option
  • Six- or eight-cylinder configuration
Can the oil be changed on a 2020 Mercedes-Benz GLS-Class without changing the filter?Oil can be changed separately, but replacing the filter with the oil keeps the new oil working through a fresh filtering element.

A loaded filter may open its bypass valve and allow unfiltered oil to circulate. Whether a separate oil change is appropriate depends on the maintenance schedule, service history, and inspection.

  • Filter holds debris carried by the oil
  • Loaded filters can trigger bypass operation
  • Service timing follows the applicable maintenance plan
