Frequently Asked Questions

6 common questions answered

Is the oil filter replaced every time a 2018 Mercedes-Benz G-Class has its oil changed?Replacing the oil filter with the oil is the appropriate service approach for a 2018 Mercedes-Benz G-Class.

A loaded filter can open its bypass valve, allowing oil to circulate without filtration. The manufacturer's maintenance schedule and the vehicle's service history help determine when the oil service is due, while the filter should be changed alongside that service.

  • Fresh oil and a clean filter work together.
  • The filter captures debris carried by the oil.
  • Mercedes-Benz of Sudbury can inspect the vehicle when you book.
What is included in an oil filter replacement on a 2018 Mercedes-Benz G-Class?The service includes a correctly matched filter, a new drain plug gasket or washer where applicable, and a post-service leak check.

The filter is matched to the engine actually fitted to the G-Class. After the engine runs, the filter seal is checked for leaks so the service includes both replacement and confirmation of the sealing areas.

  • Filter matched to the engine's specification
  • Drain plug gasket or washer where the engine uses one
  • Leak check at the filter seal after running the engine
What happens if the oil filter on a 2018 Mercedes-Benz G-Class is not replaced?If the filter loads with debris and is not replaced, its bypass valve can allow unfiltered oil to circulate.

The engine still receives oil, but that oil is no longer receiving the filter's debris-capturing function. An oil-pressure warning or an engine that sounds noisier than usual deserves attention, and service history helps determine the next maintenance step.

  • A loaded filter may trigger bypass operation.
  • Oil can circulate without being filtered.
  • Mercedes-Benz of Sudbury can check the filter and sealing area.
Does a 2018 Mercedes-Benz G-Class need a specific oil filter?Yes, the filter must be matched to the G-Class engine, and filters are not interchangeable across engines.

The 2018 Mercedes-Benz G-Class range includes engines from 4.0 to 6.0 liters and eight to twelve cylinders. Matching the filter to the engine actually installed is therefore part of the service; no part number is needed to book the work.

  • Engine displacement range: 4.0 to 6.0 liters
  • Engine cylinder range: eight to twelve
  • The replacement filter is selected for the fitted engine
Can the oil be changed on a 2018 Mercedes-Benz G-Class without changing the filter?The oil filter should be replaced alongside the oil so debris is not carried into another oil-change cycle.

The filter holds material removed from circulating oil, and a loaded filter can open its bypass valve. The manufacturer's maintenance schedule and the vehicle's service history determine when service is due, but replacing the filter with the oil keeps the filtration function current.

  • The filter captures debris from the oil.
  • A bypass valve can send oil around a loaded filter.
  • Booking the combined service replaces both together.
