Frequently Asked Questions

6 common questions answered

Is the oil filter replaced every time a 2023 Mercedes-Benz GLS-Class has its oil changed?The oil filter should be replaced with the oil change when the service calls for oil and filter replacement.

The filter captures debris carried by the oil and can load over time. Once loaded, its bypass valve opens and oil circulates without filtration. The precise timing is determined by the manufacturer’s maintenance schedule and the vehicle’s service history.

  • Filter matched to the installed 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 2023 Mercedes-Benz GLS-Class?The service includes an engine-matched filter, a new drain plug gasket or washer where applicable, and a leak check after the engine runs.

The filter is replaced alongside the oil rather than carried into another change. Mercedes-Benz of Lynnfield checks the filter seal after operation to help identify leaks at the sealing area.

  • Filter matched to the six- or eight-cylinder engine fitted
  • Replacement sealing washer or gasket where used
  • Post-service inspection for filter-seal leaks
What happens if the oil filter on a 2023 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 oil cleared of the debris the filter was holding. That change can happen quietly, without an immediate major fault. An oil-pressure warning or unusually noisy engine should prompt service attention.

  • Debris remains in the oil circulation path
  • The bypass valve may open as the filter loads
  • Oil and filter service can restore normal filtration
Does a 2023 Mercedes-Benz GLS-Class need a specific oil filter?Yes, the filter is matched to the engine, and filters are not interchangeable across engines.

The GLS-Class engine range includes 2,999 to 3,982 cc and six- to eight-cylinder configurations. Mercedes-Benz of Lynnfield selects the filter for the engine actually fitted to the vehicle, without relying on a one-size-fits-all component.

  • Engine displacement range: 2,999 to 3,982 cc
  • Engine configuration range: six to eight cylinders
  • Filter selection follows the installed engine
Can the oil be changed on a 2023 Mercedes-Benz GLS-Class without changing the filter?The oil can be changed separately, but the filter should be replaced when the scheduled service calls for an oil and filter change.

Keeping a loaded filter in service can allow the bypass valve to open and circulate unfiltered oil. The appropriate service depends on the manufacturer’s maintenance schedule, an inspection, and the vehicle’s service history. Combining the work keeps fresh oil with fresh filtration.

  • Filter condition affects oil filtration
  • Service timing follows manufacturer guidance
  • Oil and filter replacement can be booked together
