Frequently Asked Questions

6 common questions answered

Is the oil filter replaced every time a 2018 Mercedes-Benz S-Class has its oil changed?The oil filter should be replaced alongside the oil service for a 2018 Mercedes-Benz S-Class.

The filter holds debris collected from the oil, and a loaded filter can open its bypass valve so oil circulates unfiltered. Replacing it with the oil keeps the filtration system ready for the new oil. The manufacturer’s schedule and the vehicle’s service history help determine the appropriate maintenance timing.

  • Filter matched to the fitted engine
  • Applicable gasket or washer renewed
  • Seal checked after the engine runs
What is included in an oil filter replacement on a 2018 Mercedes-Benz S-Class?The service includes a correctly matched filter, a new drain plug gasket or washer where required, and a leak check after operation.

The technician installs a filter suited to the engine specification rather than relying on a universal fit. The sealing component is renewed when the engine uses one. Running the engine afterward allows the filter seal to be checked for leaks.

  • Engine-specific filter fitment
  • New applicable sealing washer or gasket
  • Post-service filter-seal inspection
What happens if the oil filter on a 2018 Mercedes-Benz S-Class is not replaced?A loaded filter can open its bypass valve, allowing oil to circulate without filtration.

The engine still receives oil, but that oil may carry debris onward instead of being cleaned by the filter. This can happen quietly, without an immediate dramatic symptom. An oil-pressure warning, a noisier-than-usual engine, or oil that darkens quickly after a change supports arranging an inspection.

  • Bypass valve may open
  • Oil can circulate unfiltered
  • Inspection can assess the service need
Does a 2018 Mercedes-Benz S-Class need a specific oil filter?Yes, the filter must be matched to the engine, and filters are not interchangeable across engines.

The 2018 Mercedes-Benz S-Class range includes engines from 2,996 to 5,980 cc and six to 12 cylinders. Correct fitment depends on the engine actually installed, not just the model name. Mercedes-Benz of Lynnfield can match the filter during the appointment.

  • Engine displacement: 2,996 to 5,980 cc
  • Cylinder range: six to 12
  • Filter selected for the fitted engine
Can the oil be changed on a 2018 Mercedes-Benz S-Class without changing the filter?Oil can be changed separately, but replacing the filter with the oil is the appropriate filter service.

The filter retains debris collected from the previous oil, and extending it across another change reduces the benefit of fresh oil filtration. The vehicle’s manufacturer schedule, inspection findings, and service history help determine maintenance needs. Ask the Service Center to address both items together.

  • Filter captures oil-borne debris
  • Loaded filters can bypass filtration
  • Service history guides maintenance decisions
